A winter’s morning in Melbourne with the Canon TS-E 17mm f/4 tilt shift lens on a Sony a7II

Written by Gary on July 28th, 2019

Last weekend I had time for a short walk in Melbourne’s mid-winter sunshine and I decided to bring along my Sony a7II with Canon TSE 17mm f/4 tilt shift lens.

I shot most of these at f/8 or f/10 hand held and with the shift position optimised for the height of the buildings while trying to keep the camera level. I used the zebra mode to manually focus although given the aperture and wide depth of field this was not going to be critical.

Some of the images I decided to shoot in continuous 3 shot AE bracketing mode in case I decided to create a HDR in Affinity Photo, although most of these were mainly processed to B&W in OnOne Photo RAW 2019.

hmm… I am not sure this has been corrected perfectly but then I am not an architectural photographer professional.

The question is, would these have been better had I used the new 61mp Sony a7R IV instead of this 24mp camera – the only way you would see the difference is if I posted a small crop or the full size images and you zoomed in to pixel peep at the detail, or perhaps if I printed a very large wall print and you moved in close to view it.

If I really wanted lots of megapixels, I could have used this 17mm tilt shift on the new Fujifilm GFX 100S 102megapixel medium format camera but then this lens behaves more like a 14mm lens, and at full shift there will be some vignetting. If you want to see more on Canon tilt shift lenses on this camera system, see this Youtube review.

Hence for most of us, 20-24 megapixels is plenty!

Why didn’t I use my Olympus OM-D E-M1 II?

Unfortunately there are no shift lens options available for Micro Four Thirds that give you 17mm field of view in full frame terms, and of course this Canon lens becomes a 34mm on Micro Four Thirds, although I could use my focal length reducer adapter to get it back to around 24mm field of view.

I had hoped someone would make a Four Thirds to Micro Four Thirds adapter with shift capability so I could use my superb old Four Thirds Olympus 7-14mm f/4 Super Pro lens in this manner but even then I am not sure the image circle will allow for sufficient shift without vignetting, but this lens does allow me to go wider at 14mm full frame equivalent which may then require less shift.

I could have used my Olympus mZD 8mm f/1.8 fisheye and then de-fished it and then adjusted keystone effect and cropped, or perhaps my Olympus micro ZD 7-14mm f/2.8 would have sufficed for this purpose – but either way, I would lose pixels and potentially a little image quality by post-processing in this way.

The Olympus OM-D E-M1 Mark II has in-camera keystone adjustments so much of the guess work can be removed which does allow for better compositions if you do have to resort to keystone post-processing.

 

Why a 61 megapixel camera is probably too much for you – post-processing may not be so much fun

Written by Gary on July 22nd, 2019

The megapixel race is apparently still on .. Sony has upped the ante in the full frame sector with their 61mp Sony a7R Mark IV which can also do a 16 shot sensor shift 240mp image.

Fujifilm has their new 100mp Fujifilm GFX100S medium format camera.

Whilst many professionals and enthusiasts have very valid reasons for needing such high resolution cameras, these come at a cost not only in terms of purchase price and file storage costs but also in terms of post-processing frustrations due to their massive file sizes.

The Sony a7R IV is said to have 124Mb RAW files and apparently if you shoot the 16 shot Hi Res image you will be up for a 2Gb file!

Unfortunately, they have not allowed you to have a full frame RAW file in lossless format at lower resolution so that means you are committed to shooting every one of your full frame shots at 61mp – although you do have an option for a 62Mb compressed lossy RAW file or a 24mp APS-C crop file.

Let’s see what happens to file sizes in post-processing

I recently decided to purchase Affinity Photo to play with as it has been many years since I used Photoshop and I am certainly not going to be paying Adobe in my retirement an annual subscription fee just so I can re-use my old edits.

So far I have been impressed with Affinity Photo, and perhaps will write a more detailed analysis of some very cool things it can do for your photography at some later time, in the meantime you can check out resource links and video links on my wiki page here.

I went for a walk up onto the nearby mount on the weekend, and yes it was cold, but I needed the exercise, and on my way up, I took this quick hand held shot with my Olympus OM-D E-M1 Mark II with the Olympus mZD 60mm macro lens (I decided to travel extra light!).

straight from camera

This was the image straight from camera with Olympus Natural profile, autoWB and just resized for the web using Lightroom v6.

The RAW file of this 20mp 12bit image was a lovely, easy to handle 19Mb – yes, no problem shooting off a hundred or so of these on a shoot, or shooting at 18fps at a sports event or capturing wildlife.

But after watching a video tutorial or twenty on how to play with Affinity Photo, I decided I would create some light rays and a touch of fog from the highlights of this image without adding in ready made ones.

sun rays and fog

After a bit of experimenting I came up with the above, I am not sure it really is an improvement on the original, I am feeling it is much like some music which has too many notes in it, but each to his own, some people like Rachmaninoff instead of Pink Floyd.

The point I have been labouring to get to is that this above file in Affinity Photo’s internal format in 16bit AdobeRGB is no longer 19Mb but a whopping 1GB thanks largely to its use of layers, and that is not even a complex post-processing case!

Now if my simple 19Mb image gets to 1Gb so easily, just imagine how your poor high end computer is going to strain with playing with a 61mp 124Mb file that is already almost 10x the size, let alone starting off with a 2Gb HiRes file!

There are better ways to improve your photography than just by megapixels

For some purposes you may just need the extra megapixels, but in many instances you actually will get better photos by taking a number of shots depending upon your needs such as:

  • managing high contrast scenes with HDR exposure bracketing
  • managing depth of field by using focus stacking
  • managing transient imagery such as fireworks by blending images in a similar way to Olympus Live Composite mode
  • managing high ISO noise by stacking 10-50 images to average out the noise
  • creating a panoramic stitch to give you more detail and more scene coverage
  • shooting a burst of images to ensure you have captured the correct moment

A high resolution camera such as a 61mp full frame may well give you 61mp but if there is camera shake, subject movement, marginal focus error, high ISO or use of an older lens, then those 61mp may well be wasted but you still end up with having to deal with the massive files.

At the top of my walk up the mount I was greeted by real sun rays, no Photoshopping here to add them in (but you can watch this video on how to add in God’s rays to your images using Affinity Photo if that’s your thing).

These scenes are not simply captured in one shot as the dynamic range is far too great – for this I resorted to a 3 shot hand held exposure bracket and then used Affinity Photo’s awesome HDR tools to align the 3 images and perform 32bit tone mapping and some contrast adjustments and cropping to 16:9 aspect ratio and a 249Mb image.

I ended up with the following lovely little shot (the individual single shot exposures looked terrible due to the high contrast, but combined, they now look more like how my eyes witnessed this scene):

Two new full frame mirrorless cameras – Sigma FP and the Sony a7R IV

Written by Gary on July 17th, 2019

The full frame mirrorless market place is becoming increasing difficult to decide upon which system to jump into as each offers something different but none offer everything you need – see my previous post on this.

We have Nikon’s Z system which only has entry level enthusiasts cameras at present without some of the features pros need and with a Eye detect AF that is still very immature compared to Sony as it seems to detect eyelashes instead of the iris, and a strange initial line up of lenses. A potential big advantage of the Nikon mount is that it can use almost any lens ever made including Sony FE and potentially, Canon RF – the question will be – how well will the AF work with these lenses. We now just have to wait and see what Nikon can do with their cameras and what native lenses they decide to bring out and whether they will be affordable.

Canon with their new RF mount has been introducing some ground breaking lenses which will be far more functional and optically better than their dSLR versions (in particular, the Canon RF 85mm f/1.2) but it has only introduced uninspiring entry level cameras and none have in-camera sensor shift image stabilisation which is now an expected feature in cameras.

Add to this the new medium format mirrorless camera with image stabilisation, the Fujifilm GFX100S with its “relatively” affordable 100mp medium format image quality and one can see there is pressure on the full frame camera manufacturers.

The new Sigma FP L mount camera

Last week Sigma, which has joined the L-mount alliance with Panasonic and Leica, announced a camera from left field – their pocketable Sigma FP full frame mirrorless camera which is designed to be the heart of a powerful, modular videography kit and allows Cinema RAW video output. You can read more about this interesting camera on my wikipedia page.

In addition, it is likely Sigma will be bringing out other interesting cameras in this mount such as a Foveon sensor for those Foveon fans.

Now that 3 companies are making cameras and lenses (and Sigma has a substantial arsenal of lens designs ready to go), the L-mount may become quite competitive – especially for videographers.

The new Sony a7R IV

Yesterday, Sony announced their 4th generation of the Sony a7R series, the Sony a7R IV which obviously targets professional photographers who need the highest resolution possible to allow their images to be utilised in a variety of ways by their clients through cropping of different parts for different output purposes.

The main differences over the Sony a7RIII are:

  • 61mp sensor instead of 45mp – this takes the pixel density and pixel size to that approaching Micro Four Thirds, but somehow Sony have maintained a high dynamic range of 15 stops for stills.
  • a new 5.76mdot EVF with 60 or 120fps refresh rate (the latter has lower resolution) – presumably the same as on the Panasonic S1/S1R
  • sensor pixel shift HiRes mode now produces 16 shot 240mp output images
  • improved shutter, grip and weathersealing around battery and card doors which have been an Achilles heel for the previous models
  • slightly greater PDAF coverage of 74% of the frame instead of 68%
  • advanced Real-time Tracking plus Real-time Eye AF for still image recording
  • new ‘Focus Priority’ mode allows camera to acquire AF at wide open aperture at a cost of increased shutter lag
  • Real-time Eye AF and Touch AF Tracking functionality for movie recording
  • anti-flicker mode
  • new Multi Interface Shoe™ with new digital audio interface delivers the high-quality sound recording with Sony’s new microphone and XLR microphone adapter
  • USB-C now has double transfer speed
  • both SD card slots are now UHS-II
  • 2.4GHz and 5GHz WiFi for improved tethering

Issues with the Sony a7R IV:

  • very large file sizes means storage issues and slower and more frustrating post-processing and one would be hard pressed to see the difference between a 45mp image and a 61mp image – you generally need to double resolution to be able to see a substantive difference.
  • what will high ISO performance be like if pixel size is now approaching that of Micro Four Thirds? 60-100mp makes sense on a medium format camera with its larger sensor – but what will be the image quality costs of such high pixel density on a full frame sensor size – we will have to await testing.
  • no option for lower resolution full frame files with lossless compression – but you can use their lossy compression files or use a 26mp APS-C cropped sensor mode
  • video features lag well behind peers and are little changed from the a7RIII with only 8bit output, the Super35mm modes are cropped more than one would like (1.6x in 24p and 1.8x in 30p) while the full width mode uses binned pixels, and no 4K 60p mode, plus rolling shutter is likely to be a major issue.
  • menu system apparently unchanged and this is in need of a change
  • seems you still can’t get your 5th finger to hold the camera which makes adding a grip more of an ergonomic necessity with larger, heavier lenses.
  • LCD is still only a tilting LCD not swivel and no good for vlogging
  • no electronic shutter faster burst modes – presumably due to slow sensor read out time as the sensor is full frame with 61mp and unlike the Sony a9 it is not a stacked sensor.

Sony has certainly upped the ante on Canon and Nikon and especially at the price point of $US3499 it will be challenging them head on and at the same time the 61mp and the 240mp HiRes mode will likely decrease the move of pros to 100mp medium format cameras.

Sony has obviously decided to leave the video capabilities to minimalistic levels given the slow sensor read out to allow for a new version of their Sony a7S series which targets videographers – but they will be having to compete with Panasonic and Sigma now for this market.

This camera will be popular for pros and gear-heads but the far majority of us do not need that resolution for all our photos and having to store all those files and have the fun taken out of your photography with the slow and frustrating post-processing experience will be a cost you have to factor in – most of us would probably be better off with a 20-24mp camera for most uses, but some without budget issues would perhaps like this camera for special uses.

As usual, I have a wiki page for the Sony a7RIV which I will update with links and resources as they arrive.

 

Upgrading to an Olympus OM-D E-M1 II from an E-M5 or E-M10

Written by Gary on July 10th, 2019

While the Olympus OM-D E-M1 Mark II Micro Four Thirds camera is getting a bit old having been announced way back in Sept 2016, the recent firmware upgrade that Olympus has kindly offered has breathed new life into it and makes it a very attractive option for those with an E-M5 Mark II or E-M10 series camera, especially if one can get it at discounted prices.

What are the main differences compared to the E-M5 series?

  • grip is built in making it bigger and with better ergonomics and build than when using an add on grip as was needed with the E-M5
  • new bigger and much longer life battery – sorry the old ones can’t be used.
  • better image quality – 20mp vs 16mp, 1 EV better high ISO noise and improved dynamic range and no low-pass filter for more detail
  • further improved image stabiliser now to 6.5EV with OIS lenses
  • much faster image processor Truepic VIII with double quad core is 3.5x faster than the Truepic VII in the E-M1 which also helps to reduce the start up time (the E-M5 II uses Truepic VII)
  • two SD card slots one of which is UHS-II compatible for even faster saving of images and video allowing faster burst rates and 4K 30p video
  • improved silent shutter – to 1/32,000th sec and 18fps or 60fps burst with much less rolling shutter and a flash sync of 1/50th sec in silent shutter mode
  • much improved AutoISO – can now use exposure compensation with it in Manual exposure mode and you can set the slowest shutter speed to use in A or P exposure modes
  • can now use the 2×2 switch as the Power On/Off switch for one handed use
  • new electronic viewfinder with faster refresh rate
  • Frame Rate Priority added to Live View Boost/On2 display
  • PASM dial now has 3 custom modes you can use BUT you no longer have Scene modes given this is meant for people who shouldn’t need to resort to these
  • automatically saves your settings to computer and restores them during firmware upgrades – and you do this manually too if you have a range of settings
  • improved HiRes mode – processor tries to reduce blur from moving subjects and now produces 50mp jpegs not 40mp
  • improved menu system
  • new AF Scan will allow users to adjust the lens scan operation settings in low-contrast environments to prevent unnecessary hunting
  • much improved video – 4K 24/30p, Cinema 4K at 237Mbps quality , much better continuous AF and image stabilisation during movies, Log profiles for better grading during editing
  • anti-flicker mode to prevent unstable exposures when shooting indoors.
  • improved Focus Stacking – from 3 to 15 shots can be selected in Focus Stacking and guide lines have been added to the shooting area
  • Support for Olympus Workspace new USB RAW Data Edit

BUT, the real benefits are in shooting moving subjects

The E-M5 series of cameras were not designed for tracking moving subjects and indeed had trouble focusing on them if they were moving too fast.

Not so with the E-M1 II, it has a multitude of features which helps the photographer capture wildlife, sports or any other moving subject much more reliably and faster than ever before in an Olympus camera, and currently is only bettered by the much bigger and much more expensive new Olympus OM-D E-M1X.

Let’s look at shutter and EVF improvements that are not on the E-M5 II:

  • EVF has faster refresh giving 60% faster response rate and virtually no blackout when following a moving subject
  • silent shutter mode allows 18fps with C-AF or an incredible 60fps with focus locked on first image (EM5II could only do 11fps) and does this with much reduced rolling shutter artefacts (see my previous blog)
  • mechanical shutter allows C-AF to 10fps and can do 15fps with focus locked on first image (E-M5 II could do 5fps with some C-AF and 11fps with locked focus)
  • much faster card writing speed and the buffer is much larger
  • you can get to 1/32,000th sec in silent mode instead of 1/16,000th sec which might be useful for freezing some subjects
  • camera does not freeze up during writing files after a burst

But the real deal is the massive AF improvements:

The biggest difference is the E-M1 series have PDAF detectors on the sensor not just CDAF detectors and these PDAF detectors work far better for moving subjects than do CDAF detectors – the E-M1 II has 121 cross-type PDAF detectors which cover 80% of each axis of the image to ensure that you have a better chance of locking onto your subject no matter where it is in the frame.

The PDAF detectors also mean far better AF performance when used with lenses from other dSLR systems such as Four Thirds (via Olympus MMF-3 adapter) or Canon EF (via AF-compatible adapters such as the Metabones adapter).

These PDAF detectors are supported by some very useful AF features, some of which are unique to the Olympus E-M1 series:

  • improved AF region options including the new 25 point region which makes birds in flight easier
  • better AF in low light – now works down to -6EV
  • new “AF Cluster Display” can display the AF points being used to track the subject in real time
  • C-AF Center Priority delivers high-precision tracking of moving subjects and sudden subject movement whereby the centre is prioritised in the Group AF target settings but if the centre cannot lock on, the surrounding points will be used
  • AF algorithms for much better subject tracking (same as the E-M1X but no AI tracking of trains, motorbikes, etc)
  • customizable C-AF tracking sensitivity allows users to choose the best setting for their subject to optimize C-AF tracking performance
  • new, unique, in-camera AF limiter to achieve faster focusing by limiting the focus range of ANY compatible lens, thus preventing time-consuming focus hunting and much more versatile than the AF limiter which is found on some lenses. You can turn this on or off easily by assigning it to one of the buttons. This is great for shooting at sports grounds where you can set it to ignore focus ranges such as the crowd on the opposite side of the ground – no other camera system can do this!
  • in-camera Preset MF lets users quickly set a focus distance when using manual focus and allows one to change rapidly from AF back to this preset MF distance – this can be turned on or off easily by assigning it to one of the buttons.
  • new “PRO Capture” can start capturing images as soon as you start to depress shutter and up to you depress shutter fully allowing lag free pre-capture of 14 RAW frames to reduce chance of missing a precise moment – this is great if you are waiting for a bird to take flight, or you are shooting someone coming over the jump but you can’t see them coming until the last second.
  • C-AF+MF1 which allows users to instantly switch to MF by turning the focus ring while in C-AF for fine tuning the focus. This requires an additional firmware update to most of the PRO lenses.
  • Once you have worked out what settings work best for your subject, you can assign these to a custom setting which is rapidly accessible from the PASM dial.

Summary

Upgrading gives you an amazing new level of capabilities, particularly for shooting moving subjects and tracking them, but learning how to use these will take some time and practice.

There are a few minor downsides to upgrading:

  • it is bigger and a little heavier – but to me this is much more ergonomic when using larger lenses such as the Olympus 40-150mm f/2.8 which I love as my main walk-around lens.
  • it is not compatible with your old batteries or their charger so you need to buy a new spare.
  • there are no Scene modes – you will have to learn how to do these yourself!
  • you will have to get used to the new control layout and menu layout

But, these are all very minor compared to the fantastic improvements you are gaining and the E-M1 II will take your photography learning experience to new levels and provide a far more versatile tool.

Of course, you could wait for the Olympus E-M1 Mark III but that could be 2020 and is likely to be much more expensive than the current discounts one can get on the Mark II, and if you don’t need any of these features, don’t waste your money and stick with what you have got.

 

Understanding why silent shutter mode is great on some cameras but is problematic on most full frame cameras

Written by Gary on July 4th, 2019

Silent shutter mode refers to a full electronic shutter being used to take the photo on a digital camera and the mechanical shutter mechanism being disabled.

Why use silent shutter mode?

  • this mode is required for shooting movies on digital cameras
  • it allows silent shooting which may be critical in low noise environments such as a classical music concert, or wedding reception.
  • it allows faster burst rates (eg. 18fps with C-AF and 60fps with S-AF on the Olympus OM-D E-M1 II)
  • it avoids excessive use of the mechanical shutter which has a limited life – most are rated at around 150,000 shots
  • it avoids shutter shock which blurs all images at shutter speeds 1/4 sec to 1/200th sec unless you use electronic first curtain shutter mode (EFCS) which is a partial electronic shutter and available on most new cameras

What are the problems with using a silent shutter mode?

  • your subject can’t hear when you take the shot
  • you may get banding when shooting in artificial light at faster shutter speeds
  • you may get distorted / slanted lines on moving subjects or if you are panning the camera – this is called rolling shutter.
  • you may have to use very slow shutter speeds when using flash otherwise only part of the image will be illuminated by the flash

Most of the problems are related to slow sensor readouts

How does a slow sensor readout cause rolling shutter?

  • a digital camera sensor must read data from each row of photosites on the sensor sequentially up or down the sensor and thus each row “sees” a potentially different scene in time
  • thus if one shoots a bus moving across the scene, the top of the bus will be imaged to one side of the image while the bottom of the bus will be imaged towards the other side of the image creating a slanting line of all the vertical lines of the bus.
  • the faster the sensor read out occurs, the more vertical is the final line in the image and the less “rolling shutter”
  • dpreview has a nice explanation here.

What are the determinants of sensor readout speed?

  • sensor readout time is determined by:
    • photosite size – larger photosites take longer to read hence a 20mp full frame sensor will be slower and with more rolling shutter than a 20mp cropped sensor camera such as Micro Four Thirds, all else being equal.
    • bit rates – a 14 bit read out takes longer than 12 bit as there is more data to collect hence some cameras revert to 12bit mode in silent shooting
    • number of megapixels – the more rows to read out, the longer it will take, this is part of the reason why high resolution full frame cameras (eg. 45mp or more) do not make great video cameras – everything is a compromise
    • engineering – some cameras (eg. Panasonic GH5) are designed to slow down the read out rate at higher ISOs to improve image noise
    • sensor design – stacked sensors generally have faster read out rates (eg. Sony a9), but these are much more complex and expensive to make

Which cameras have moderately fast sensor readouts and minimal rolling shutter?

To put this in perspective analog film movie cameras which have a rotating shutter mechanism have the equivalent of sensor readout of 5msec or 1/200th shutter speed, and this is also a similar amount when shooting with film or digital cameras in mechanical shutter mode.

Digital cameras with similar rolling shutter capabilities in electronic mode include the Arri Alexa Mini video camera, the Canon C300 II video camera, and uniquely in the still camera market, the Sony a9 with its stacked sensor design.

Cropped sensor cameras such as the Fuji XT-3, Panasonic GH-5, Olympus OM-D E-M1X and Olympus OM-D E-M1 mark II all have minimal rolling shutter thanks to a sensor read out of 20msec or faster (note the GH5 has a much slower sensor read out if shot above ISO 800).

Which cameras have slow sensor readouts and thus problematic rolling shutter?

Apart from the Sony a9, ALL full frame and medium format cameras have relatively SLOW sensor readout times of around 30msec or slower, with the Fujifilm GXF 50S medium format camera coming in at a whopping 250msec or incredibly slow 1/4 sec, the Sony a7RIII at 70msec or 1/15thsec, the Nikon Z7 and Nikon D850 at 64msec or 1/15thsec (although it can get to 1/40th sec in cropped mode), Nikon Z6 at 44msec or 1/22nd sec, Sony a7III at around 1/15th-1/30th sec.

Older cameras have slower read outs such as the Olympus OM-D E-M1 mark I which had a read out time of 77msec or 1/13th sec.

I would avoid using silent shutter mode on these cameras for sports!

How can you measure your camera’s sensor read out time?

There are several ways of measuring this and perhaps this creates the variances on the measurements people quote on the internet for each camera.

The easy way is to set the camera in silent shutter mode and ensure the camera is set to allow flash in silent mode (this may be a menu setting), then take shots at different shutter speeds and the fastest shutter speed that has the full image illuminated by the flash is the read out.

Some people measure the degree of distortion of rotating vertical lines, and others use oscilloscopes.

How will this issue be fixed in the future?

In the short term, perhaps stacked sensor technologies will be more utilised as with the Sony a9 but this is complex and expensive.

In the medium term (perhaps 5-10 years), we will see sensors with “global read outs” (ie. sensor read out time difference from top to bottom of sensor will be zero) developed which address the current problems of complexity, image noise and cost. These will be game changers as these will not only eradicate rolling shutter, artificial light banding but allow flash sync at any shutter speed and be far more effective than the very limiting current high speed shutter (HSS or Super FP) modes on current cameras.

Pros and cons of using teleconverters

Written by Gary on June 29th, 2019

Most camera systems have at least two teleconverters (“TC”) – a 1.4x and a 2x power (new camera systems such as Canon R and Nikon Z are yet to develop these).

These little devices are designed to sit between the camera and the lens and contain optical lenses which magnify your image according to which strength you have.

These are also called tele-extenders – not to be confused with a macro extension tubes which have a different function – that of allowing more magnification by allowing you to focus more closely.

Benefits of teleconverters

These are light, small and relatively inexpensive (although high quality ones may set you back $500-$1000 – but this may still be cheaper than buying a more powerful lens and certainly lighter and more compact than carrying two lenses).

A 1.4x teleconverter will give you a bit more “zoom” effect, so your 200mm lens effectively becomes 1.4 x 200 = 280mm in focal length.

A 2.0x teleconverter will give you a lot more “zoom” effect, so your 200mm lens effectively becomes 2 x 200 = 400mm in focal length.

This increased magnification can also be very handy for close up macrophotography work where magnification may be important, for instance the Olympus 300mm f/4 lens when used with the Olympus MC-20 2x TC can give almost 1:1 macro in full frame terms at its close focus of just under 1.5m which is great for shooting insects without scaring them too much!

It can prevent dust entering your sensor in adverse conditions if you have two telephoto lenses which you interchange but leave the teleconverter in place.

Some teleconverters are designed so that they can be “stacked” to multiply the effect but this also multiplies the cons. Most modern ones can’t be stacked as they are designed to be used only with certain lenses and they have a protuberant inner component which prevents stacking being possible.

Cons of teleconverters

As I repeatedly state on my blog posts, EVERYTHING in photography is a compromise, in this case you get extra magnification with minimal weight and size, but there are MANY downsides to this.

  1. your aperture is reduced
    • a 1.4x TC reduced your aperture by 1.4x (ie. 1 f stop) so that your f/2.8 lens becomes f/4
    • a 2x TC reduced your aperture by 2x (ie. 2 f stops) so that your f/2.8 lens becomes f/5.6
    • this mans that you may need to increase your ISO (and lose image quality) and / or, slow down your shutter speed (and increase camera shake or subject movement blur)
  2. your image quality is reduced
    • adding extra optical elements is almost certain to degrade your image quality although the high performance modern TCs keep this to a minimum (perhaps a reduction of 5-15% with prime lenses and 15-25% with zoom lenses), but you still may in effect lose half a stop or so of sharpness, requiring you to stop your aperture down to obtain optimum sharpness at the expense of ISO or shutter speed.
    • TC’s are prone to increasing distortion, coma, astigmatism, spherical aberration and chromatic aberration, especially when mated with complex zoom lenses
    • TCs lower contrast due to adding reflective surfaces.
    • if your aperture is f/8 or smaller, diffraction issues may further reduce sharpness.
  3. your autofocus speed is likely to be reduced, especially in low light
    • the reduction in light transmission means the AF sensors will have a more difficult time, especially in low light levels
    • many dSLR PDAF cross-points either cease to function or lose their cross-point capability at f/5.6 or smaller meaning you may have to resort to only using the centre point.
  4. you may actually lose AF capability
    • some cameras (especially dSLRs) are not able to AF if the wide open aperture is smaller than f/8 and some will only be able to AF using the centre point at f/8 – this issue has largely been eradicated with mirrorless cameras
  5. its another element that may cause failure
    • the extra element may cause failure of weathersealing, failure of electronic communication between camera and lens, and extra wobble which may contribute to the above as well as causing optical misalignment issues.
  6. you may only be able to use it with certain lenses
    • most modern TC’s can only be used with certain telephoto lenses – usually the expensive “pro” lenses
  7. it may alter the biomechanical ergonomics
    • the extra distance from camera to lens may make a heavy lens feel even more heavy due to the physics of levers.

What are the alternatives?

Essentially you only have two alternatives if you need the extra magnification.

Crop your image:

Cropping your image has MANY benefits over TCs – you get to have your normal AF capability, your normal ISO and shutter speed to optimise image quality (no point using a TC to get extra magnification if the image is blurred from longer shutter speed, you couldn’t lock focus or the higher ISO impacted image quality too much).

To gain the same effect as a 1.4x TC, you will lose half of your pixels so that your 20 megapixel image becomes 10 megapixels – still plenty for most purposes. This is my preferred approach.

To gain the same effect as a 2x TC, you need to lose 75% of your pixels so that your 20 megapixel image becomes 5 megapixels – perhaps enough for some purposes – but you would probably better having a 20mp 2x cropped sensor camera in the first place instead of carrying a heavy, expensive full frame lens around and only using 25% of its image capabilities and those 25% of pixels are probably not going to be as sharp as a dedicated Micro Four Thirds lens which is optimised for such cropping.

Buy a more powerful lens:

This may actually be more cost effective than an expensive 2x teleconverter and provide at least as good a result even if the lens is not a “pro” lens.

A good example is when you try to mate a very good zoom lens such as the Olympus 40-150mm f/2.8 with an excellent 2x TC and you get similar results as a more powerful but lower aperture zoom lens such as the Panasonic 100-300mm f/4-5.6II lens and you may get better AF in the process. You may find that you will prefer to have both lenses rather than buy the 2x TC.

Unfortunately, buying a more powerful lens may not be possible – if you are already using the biggest, most expensive lens you can afford – then using a TC or cropping is the only options you have left, but if your big lens is a prime lens with wide aperture then you may still get superb results with a TC specifically designed to be mated with that lens.

I have a wikipedia page dedicated to teleconverters with links to teleconverters from the main camera systems HERE.

UPDATE:

Since writing this post, I discovered a great YouTube discussion by Steve Perry based on his experiences with Nikon dSLRs and super-telephotos.

He concludes that using a 20mp 1.5x cropped sensor dSLR will give better results than a 20mp full frame dSLR with a 1.4x TC when using the same lens wide open. The TC not only degrades sharpness by 5-15%, but you lose contrast, lose any ISO advantage of full frame due to the loss of 1 stop aperture, and you may lose most of your PDAF AF cross-points at f/5.6 making your AF more problematic. If you try to get sharper images by stopping down then you run into image degradation by high ISO and potentially diffraction aberrations.

There is no logical reason to assume that the above does not also extend to using a 20mp Micro Four Thirds camera vs a 20mp full frame camera with a 2x TC and a similar focal length and aperture lens.

 

The saga of lens flange distance and lens adaptability is coming to a head – an AF Sony FE lens to Nikon Z adapter – the ring to rule them all?

Written by Gary on June 21st, 2019

When Micro Four Thirds became the first mirrorless camera system, its very short 20mm sensor to lens mount distance (“lens flange distance”) allowed it to became THE MOST ADAPTABLE camera system out there.

You could get adapters for nearly any lens ever made including those made for Leica M rangefinder cameras which could not be fitted to any dSLR.

Enter Sony NEX system

Then along came Sony with their NEX / E mount cameras with a lens flange distance of 18mm which could match the Micro Four Thirds system for lens adaptability. Sigma produced their Canon EF lens MC-11 adapters with AF capability which was not really realised until the version III Sony a7’s were developed to optimally utilise the AF capabilities with this adapter.

This Canon EF adapter helped Sony in that it made up for its deficient native FE lens mount line up which takes a few years to mature from inception and which is still quite incomplete.

BUT now we have the adapter for Nikon Z system

Last year Canon, Nikon and Panasonic announced their full frame mirrorless systems and whilst Canon, Leica SL and Panasonic went for a 20mm lens flange distance (the same as Micro Four Thirds), Nikon went for an extremely short lens flange distance of 16mm.

While one would expect lens adapters for dSLR lenses to be made for both systems, this week, Techart took a lot of us by surprise in producing an ultra-thin 2mm lens adapter which will allow Sony FE lenses to work on Nikon Z cameras and provide C-AF and Eye AF functionality!

The ramifications of this adapter are considerable, especially for Nikon users who want to get into the Nikon Z system but are frustrated by the lack of native lenses.

Now they can use almost any lens ever made via adapters to the Sony FE mount added onto the new Techart TZE-01 adapter – although using multiple adapters does risk inaccuracies of lens alignment and AF due to slight degrees of mount wobble.

Obviously such an adapter is impossible for the Canon R system – these users will have to rely upon the Canon EF lens adapters which Canon have made available from the start – although there are very few Canon EF lenses optimised for mirrorless cameras.

We can expect a Canon RF lens to Nikon Z camera lens adapter in the near future too which would bring the Canon RF 50mm f/1.2 and 85mm f/1.2 lenses to the Nikon Z world. We could also expect a Leica SL / Panasonic S lens to Nikon Z camera adapter.

One could even imagine Nikon making a higher resolution 60-100 megapixel Nikon Z camera and then by using a Micro Four Thirds lens to Nikon Z adapter, it could be used in 1.5-2x crop mode to utilise the superb optics of the Olympus and PanaLeica MFT lenses.

Perhaps Olympus might even consider making a Nikon Z mount style full frame camera to keep compatibility with their Micro Four Thirds lenses.

Who would have thought a year ago that the LEAST adaptable dSLR full frame camera system – the Nikon F, would be replaced by the MOST adaptable full frame mirrorless system – The Nikon Z.

As improvements in photography technology are mainly concentrating on AF performance, especially specific subject tracking and AI tracking technologies, it will be interesting indeed to see how well these will translate across platforms.

We already have cross-platform system-independent flash systems thanks to Godox and Cactus, now perhaps we are heading to a truly cross-platform lens world – and the Nikon Z camera system would be able to take the most advantage of this.

Fascinating times indeed – but it does make choice of camera system and lenses to buy into that much more complex to make sure you get the system that meets your current and future needs.

 

Portrait photographer kits compared – Fujifilm medium format vs Sony vs Canon RF

Written by Gary on June 21st, 2019

This short little blog post is a quick comparison of camera-lens kits for under $AU10,000 for the professional portrait photographer wanting a 85mm field of view lens and lots of megapixels.

Fujifilm GF 50R with 110mm f/2 lens

For THE BEST image quality under $AU10,000, this is the combo for you!

This 50mp weathersealed medium format rangefinder with a 0.79x crop factor that is not too heavy in itself mated with a very nice albeit heavy portrait lens with lovely bokeh and sharp wide open.

You can pick this kit up at the moment in Australia discounted to $AU9,850 and it will weigh 775g for the camera plus 1010g for the lens giving a total of 1.8kg. The lens gives the equivalent 35mm full frame effect of a 86mm f/1.6 lens which is perfect for portraiture.

The main downsides apart from cost and weight are that the closest focus is 0.9m, flash sync is only 1/125th sec, mechanical shutter only gets to 1/4000th sec, and the camera does not have PDAF or image stabilisation. The AF can be a bit slow and noisy compared to full frame peers and will not track the eye as well as the others in this post.

Sony a7RIII with Sony 85mm f/1.4 GM

This 45mp 35mm full frame camera is the smallest of the group and has the best Eye tracking AF and the best image stabilisation of the full frame cameras. This is the most popular combination for pros using mirrorless kits for the portraiture or fashion work.

You can pick this kit up in Australia at the moment for $AU5,290 and it will weigh 657g for the camera and 820g for the lens making it 1.5kg although for a lens of that weight you will probably need to add a camera grip as this camera is too small (see my earlier blog).

This will give you slightly narrower DOF than the Fuji 110mm and slightly closer focus at 0.85m and of course you get the IBIS, more silent and faster AF.

If you don’t need 45mp, you could save around $AU750 and get the 24mp Sony a7III instead. You could buy 3rd party lenses instead but Eye AF tracking may not be as effective.

For the budget minded, one could resort to the much older 24mp Sony a7II for $AU1450 which has image stabilisation but the Eye AF is no where as good as the version III cameras, and mate that with a Sony 85mm f/1.8 at $AU880, making the kit $AU2330.

Panasonic S full frame cameras

At present Panasonic do not have a wide aperture portrait prime lens, and you would need to resort to the Leica 90mm f/2 or Sigma ART 85mm f/1.4 and there may be compatibility issues that still need addressing as it is early days.

There are no budget level cameras as yet.

Nikon Z7 full frame camera

Nikon are yet to produce a native wide aperture portrait prime lens although a 85mm f/1.8 is due to be announced this year, but professionals will be waiting eagerly for a f/1.4 or f/1.2 pro lens.

Reports suggest that when used with the 105mm f/1.4 dSLR lens, the Eye AF focuses on the eye lashes instead of the iris – but I am sure Nikon will sort this out soon as they are early days in their technology.

There are no budget level cameras as yet.

Canon R with Canon RF 85mm f/1.2 lens

For those after the narrowest DOF, this could eventually be the killer combo when Canon releases a pro full frame mirrorless camera and by all accounts this lens is far better than the old Canon EF 85mm f/1.2 lenses for dSLRs.

This combo will be available for around $AU5,000 (lens is not yet available) and will weigh 580g for camera and 1200g for lens making it 1.6kg, and again it would benefit from a camera grip. Close focus is 0.85m.

The Canon R has reasonable Eye tracking AF but unfortunately no image stabilisation in camera or in the lens, the camera is not weathersealed and is only 30mp and does not feature the functions pros would want – hence they will be hanging out for a higher resolution professional camera, and preferably one with IBIS.

The budget entry level alternative is the Canon RP with EF adapter for $AU1775 and a legacy Canon EF 85mm f/1.8 lens for $AU500 making the budget kit $AU2225 but no weathersealing, no image stabilisation, and only 5fps burst.

Olympus OM-D E-M1II with Olympus 45mm f/1.2 lens

I have added this in here, because many will value lower cost, lower size, lower weight, better weathersealing, better image stabilisation, and faster burst rates and smaller file sizes than any of the above while the DOF is perfect for most portraiture but won’t get you quite as narrow a DOF as it equates to 90mm f/2.4 and this may not suffice for the pros for full length body shots.

This kit can be bought in Australia at present for $AU2,700 and will weigh 574g for the camera and 410g for the lens making it a nicely balanced kit at just under 1kg. The lens will also focus much closer than the above at 0.5m.

The downsides are up to 1-2EV less narrow DOF, 1-2EV worse image noise at higher ISO (although most pros prefer to shoot portraits at f/2.4 with their 85mm lenses to ensure they get nose to ear in focus, and as this is achieved at f/1.2 on the Olympus, the Olympus can shoot 2 stops lower ISO which negates much of the full frame advantage), and only 20mp 12 bit file sizes, and the Eye tracking is not quite as good as the Sony.

A Panasonic Micro Four Thirds alternative to this kit is the Panasonic G9 + Panasonic 42.5mm f/1.2 lens.

A budget entry level kit into this system with image stabilisation and Eye detect AF would be the Olympus OM-D E-M10 III with tiny, light Olympus 45mm f/1.8 lens which would come in well under $AU1000 but you don’t get weathersealing, AF with moving subjects and the DOF equates to 90mm f/3.6 which is a reasonable compromise for the price

A nice APS-C cropped sensor alternative is the 26mp Fujifilm X-T3 camera with a Fujifilm XF 56mm f/1.2 R APD which gives 84mm f/1.8 equivalence and has an apodization filter to produce nicer bokeh but at a cost of 1EV light transmission. Unfortunately this kit requires an optional hand grip and will not give you image stabilisation (you would need the Fuji X-H1 camera for this but the AF is not as good and only covers 37% of the image area and it is 140g heavier). The XT-3 kit will cost you around $AU3000 on discount and will weigh 489g for the camera and 405g for the lens totaling 0.9kg.

As mentioned in previous blog posts, choice of camera is always a compromise between price, weight, size, image quality and feature set – there are no perfect cameras to suit all needs perfectly.

Oh, and here is a challenge – can you work out which camera took which portrait image – Fuji Medium Format vs Full Frame vs Fuji APS-C vs Micro Four Thirds – see here. These all have the same field of view and DOF – so the viewer can concentrate on dynamic range, etc – I must say I find it very difficult to tell them all apart. The results of viewer polls also showed that viewers were not able to consistently tell them apart either!

 

Olympus announce firmware update for OM-D E-M1 Mark II

Written by Gary on June 20th, 2019

Olympus has just announced new firmware (v3.0) for the Olympus OM-D E-M1 II Micro Four Thirds camera which endows it with many of the new features introduced in the very expensive Olympus OM-D E-M1X.

This will be a much loved firmware update for sports, action and wildlife photographers in particular, but it also adds some videography features – namely the OM-Log400 video profile and better AF performance during video through actively using data from the On-chip Phase Detection AF sensor .

It is great to see Olympus making such improvements to a camera which is now almost 3 years old since it was announced in Sept 2016, which came 3 years after the Olympus OM-D E-M1 original version which was announced in Oct 2013.

The official news release details can be found in THIS PDF.

New improvements from the E-M1X:

  • enhanced AF algorithms
  • adds Group 25 to AF Target which will be fantastic for many subjects such as birds in flight – this is a feature I have been wanting for a long time – thank you Olympus!
  • adds C-AF Center Priority delivers high-precision tracking of moving subjects and sudden subject movement whereby the centre is prioritised in the Group AF target settings but if the centre cannot lock on, the surrounding points will be used
  • adds C-AF+MF1 which allows users to instantly switch to MF by turning the focus ring while in C-AF for fine tuning the focus. This requires an additional firmware update to most of the PRO lenses.
  • AF low light limit now down to a very low light level of -6EV with f/1.2 lenses
  • anti-flicker mode has been added to prevent unstable exposures when shooting indoors.
  • improved Focus Stacking – from 3 to 15 shots can be selected in Focus Stacking and guide lines have been added to the shooting area
  • improved burst mode – setting changes and playback display while writing to card now possible
  • new Art Filter – Instant Film
  • Quick image selection added
  • Frame Rate Priority added to Live View Boost/On2 display
  • Improved jpeg quality – 1/3rd EV better image noise
  • adds Low ISO Processing (Detail Priority) and Low 64 and Low 100
  • Support for Olympus Workspace new USB RAW Data Edit

E-M1X features you don’t get in the update:

The E-M1X obviously has some hardware features that the E-M1II does not have such as the in-built vertical grip with extra battery storage, dual UHS-II card slots, Bluetooth, GPS/Field sensor system, multi-selector tool, improved sensor cleaning system, USB-C port with in-camera battery charging, higher rated shutter mechanism, new EVF features, and the 2x faster engine processing capability which affects many aspects of the functionality such as the AI Intelligent AF Subject Tracking mode, 120p video mode, the improved 7.5EV IBIS which makes hand held HiRes mode and Live ND mode possible.

There are some features that one would think could have made it to the E-M1 II from the E-M1 but which didn’t such as:

  • Custom AF target
  • the new customizable ‘My Menu’ tab

How to get the firmware update:

The Olympus firmware update website is HERE.

You must first install the Olympus Digital Camera Updater software from the above link.

Make sure your camera has a full battery and connect camera to computer using the USB cable and choosing USB Storage mode on the camera options.

Run the Olympus Digital Camera Updater software and follow the instructions ensuring you don’t turn off the camera before it is complete.

Run the process for each PRO lens you have by attaching the lens to the camera (you should turn off the camera before changing the lens) and follow the above but this time it should only display the lens firmware update option.

What next for Olympus?

It was 3 years from the original version to the mark II, and 3 years from the mark II will be Sept-Oct 2019, so we could see the E-M1 III this year. In which case, this firmware update is a good marketing policy as it will allow the E-M1 II to still be produced relatively competitively for perhaps another year at a lower price point than the E-M1 III.

Perhaps a bigger question is what will Olympus put into their E-M1 mark III?

I would hope it does get the new 2x faster image processing engine of the E-M1X so it can get a range of the features of the E-M1X outlined above but is there sufficient room for this chip?

I would think it would get the E-M1X’s dual UHS-II card slots, Bluetooth, GPS/Field sensor system, improved sensor cleaning system, and USB-C port with in-camera battery charging.

But for it to be competitive in the market with very capable cameras such as the Fujifilm XT-3 and Sony a7III, all these features would need to be added but the price kept around the price of the current E-M1 II.

It will be interesting to see if they use a new generation sensor such as the newly developed multi-layered sensor for much improved image quality capabilities.

 

Which full frame mirrorless camera system to buy into? A goldilocks conundrum but none are just right … yet.

Written by Gary on June 16th, 2019

2018 was the year the major camera manufacturers got serious about full frame mirrorless cameras, and yes, they are the future of photography instead of dSLRs because that is where the greatest technological improvements can be made thanks to the full time use of the sensor and the electronic viewfinder.

But which camera system should one buy into?

This is not an easy choice because buying into a system will make it expensive to swap systems later if you find it doesn’t suit your needs, and none of the current offerings are ideal tools.

The camera needs to become a seamless extension of the photographer’s “performance” and provide a comfortable, ergonomic and efficient mechanism to achieve their goals.

The camera system needs to have all the lenses and capabilities that the photographer is likely to need – although this will vary for individual photographers.

Sony has the most mature native system at present thanks to their head start of some years over Canon and Nikon with Canikon users needing to rely upon legacy dSLR lenses to address current needs. Panasonic is the new boy on the block for full frame and although there are some expensive Leica lenses available and Sigma will be joining their lens mount system, users will have to wait some time before this system matures.

Can I love the Sony system?

I come from decades of using Olympus gear and a Canon 1D Mark III pro sports dSLR, and when I bought a Sony a7II camera a year or so ago because it was cheap and I could use my Canon EF lenses on it, I have had quite some time to play with it and try to like it.

Frankly I hate using the Sony a7II – but perhaps the Sony a7III has addressed all my issues – but it seems it has only addressed some of them.

Sony seems to have accidentally created their full frame system, they created the APS-C cropped sensor NEX camera system and then realised that they could actually squeeze a full frame sensor into the same lens mount and camera size – a pretty cool feat indeed!

BUT, the lens mount system is not really optimised for full frame sensors as it is a touch too small which may cause some future lens design and sensor IS issues, and at present they have persisted with the same camera size for their a7 series which is TOO SMALL to comfortably hold the required larger, heavier full frame lenses.

I can get past the poorly conceived Sony menu system, but not the poor camera ergonomics.

Even with my small hands, my 5th finger falls uncomfortably below the bottom of the grip which is also not as deep as it could be, while the thumb on the rear feels unstable and it is actually difficult to rotate the quite stiff rear dial with your thumb holding the camera one handed.

Sony needs to take a leaf out of the Olympus camera designs

Now Olympus have not always had the best designs for ergonomics.

The revolutionary OM film cameras were amazingly small and light when compared to the behemoths of the day, but they had no ergonomic grip built in as these cameras did not have image stabilisation nor autofocus so the user was expected to use a two hand approach to address this and as such a grip was not needed.

Enter the digital SLR world and Olympus experimented with many grip designs over the years, including the downright ugly E330 which I owned and then the much improved E510.

Then Olympus changed the mirrorless world with their fantastic compact OM-D E-M5 which was beautifully designed for using with the initial compact lenses but did require an extra grip for the larger lenses and this extra grip proved to be a weak point.

But now they have evolved to the Olympus OM-D E-M1 II which for me gets close to the perfect feel of a camera in the hand, even with larger lenses.

Why can’t Sony make their a7 range a touch taller with a deeper grip and a thumb and dial control similar to the E-M1 II, plus throw in a swivel LCD and I think I would actually love their system – for one can’t fault their class leading sensor image quality nor their class leading AF tracking capabilities in their version III cameras.

That said, they should not follow the Olympus On-Off switch position veing placed on the left side which requires two-handed operation (this harks back to their OM film SLR designs but is not ideal now) – this is one area where Sony has probably got it right – put it on the shutter release button.

What about the new Canon R series?

This is a difficult one for me because I have lots of pro Canon EF mount lenses and would love to use them on a Canon mirrorless full frame camera.

The current cameras (both are consumer level quality only even the Canon RP) do not address my needs – in particular, they are now the only full frame mirrorless cameras without sensor based IS. Canon has introduced some controversial user interface controls which we will have to wait and see how they pan out, and they are not weathersealed, nor do they have dual card slots, nor do they have a fast burst rate or silent electronic shutter mode, and the video capability is crippled. They even crippled their USB-C port to only USB 2.0 speeds – really Canon?

I do like the new RF f/1.2 prime lenses as these bring for the first time to full frame, fast, accurate AF with very high image quality wide open for lenses such as these – but they are very expensive indeed!

Their list of native lenses is very much early days so we will need to wait and see how this matures and if Canon decides to add IBIS in to their cameras.

The Nikon Z series?

These look very promising although their AF tracking is not quite up there with Sony yet, and perhaps more troubling is their initial native lens line up decisions. The burst rate with Live View update, AE and AF is limited to 5.5fps and the buffer is very limiting for sports or wildlife.

For me they are not on my plans given my Canon EF lenses would unlikely to be able to be used well on them even if an adapter came out.

That just leaves the Panasonic S system.

This looks like it will be a fantastic system, but it will be big, heavy and expensive – everything that I try to avoid.

Where does that leave me?

Waiting for Canon to add IBIS and add some proper features, or Sony to fix their camera ergonomics and add in a swivel LCD screen and make them as comfortable, as weathersealed, and as capable as my E-M1 II.

Or perhaps Olympus will show them all how to design a full frame mirrorless camera properly – but I doubt they will waste money venturing into that competitive world with a falling market.

For my needs at present, the Micro Four Thirds system is the most optimal in terms of weight, size, image quality and cost – I wont be taking my Sony a7II and large, heavy Canon EF lenses on my overseas holidays.

Perhaps I will skip full frame and supplement my Micro Four Thirds go anywhere system with a medium format mirrorless system such as the Fujifilm GF system – although I really can’t see myself getting much benefit from it.
