Macrophotography in a digital age
For ease of use, best combinations are:
- Olympus E3 with Four-Thirds system macro lens +/- macro flash system:
- articulating live preview LCD screen for ease of use in accurate
manual focus and assessment of DOF
- 5 stops image stabiliser which works with any Four-Thirds mount lens
and legacy lenses too if you buy the special lens adapter with a chip
with lens focal length information embedded in it - not sure how well it
works though.
- 2x crop sensor for more DOF and more effective working distance from
subject
- fastest AF in low light if you decide to use AF
- ZD 50mm f/2.0 macro lens is great for macro work down to 1:2 (need
extension tube or 2x TC for 1:1) - hopefully Olympus will bring out a
new SWD version with a focus limiter for even faster AF.
- Nikon D300 or D3 with Nikkor VR macro lens:
- non-articulating live preview LCD screen
- less noise at high ISO, so maybe better for moving subjects without a
flash, but if they are moving, you generally need fast AF with a flash
so the Olympus E3 will be a better bet.
- marginally more dynamic range may be important in a few circumstances
Summary:
- digital cameras have made macro work so much easier and more fun.
- there are lots of cheap ways of achieving pretty good macro photos.
- for flash photography:
- external, off the camera flash photography is often needed and for
this TTL flash makes life so much easier, special lens mounted
"ring flashes" can also be used but tend to give flat
lighting.
- the main difficulty is ensuring your subject stays in focus - even
small camera movement when hand held may put the subject out of focus.
It is very hard to achieve hand held at magnifications greater than 1:1,
thus use a tripod if possible.
- consider bounce flash to avoid excessive reflections from shiny
subjects.
- both Olympus & Canon provide either Twin Flash or Ring Flash but
either system requires cords and perhaps do not integrate as well with
other flashes as does Nikon's wireless i-TTL system although Nikon do
not provide a ring flash.
- Canon's unit does allow it to wireless control other flashes via
E-TTL.
- for available light, you will need:
- a sturdy tripod, preferably with an adjustable stage to help adjust
the camera to subject distance
- a camera that allows mirror lockup to minimise vibrations (or a camera
with no mirror at all)
- if hand-held, an image stabiliser or low noise at high ISO, or both.
- good, accurate manual focus is critical.
- choose camera position, etc to ensure background is not distracting
- of the digital SLR's:
- the best options would be the Olympus E330,
Olympus E510, Olympus E3, Nikon D300, Nikon D3 or Canon 1D Mark III :
- live preview LCD screen which not only gives the most
accurate manual focus available for macro work but allows one to
accurately frame (100% view) with accurate DOF preview as well as
allowing one to not have to have your eye on the lens.
- even better if the live preview screen can be moved out for easier
ground level use:
- better still when not using flash is a camera that allows image
stabiliser with macro lenses:
- Olympus E510 or E3 with ZD macro lenses
- Nikon D300 or D3 with Nikkor VR macro lens
- In addition, the Olympus E system allows almost any lens to be
used (except Canon EOS).
- for hand held available light work the BEST options are either:
- Nikon D300, or Nikon D3 with Nikkor VR macro lens
- Olympus E510 or Olympus E3 with its IS combined with ZD 50mm f/2.0 macro
lens
- on a windy day or a moving subject without flash, the Nikon D3 or Canon 1D Mark III
becomes the best with its low noise at high ISO allowing faster
shutter speeds and maybe one day they will add an IS lens to
make it the best for stationary subjects too (Nikon have one).
- the wireless remote live preview and camera control adds
interesting possibilities for nature work.
- for photomicroscopy, best results with greatest ease of use
are with a live view dSLR which can be remotely controlled, has
mirror lockup and has HDMI live video out:
- although great results are possible with the Canon EOS cameras, their
electronic coupling makes life more difficult and expensive for various
macro options and apart from the 1D Mark III and 40D, the Canon dSLRs do not have good manual focus aids.
- Canon do make an interesting manual focus macro lens, the MP-E
65mm f/2.8 macro which unlike most lenses does not focus at
infinity, but focuses from 1:1 to 5:1 on a full frame camera.
- the other brands are pretty much equal in terms of macro work, but do
not have good manual focus aids unless they have live preview.
- of the macro lenses:
- unless you need AF, consider using Olympus OM or Nikon F lenses as
these can be used on both Canon and Olympus (as well as Nikon/Fuji if its a
Nikon).
- if a long working distance is not needed:
- Olympus:
- ZD 35mm f/3.5 macro gives 1:1 and is relatively cheap but
still high quality
- for nature macro work, a long working distance becomes important and
usually with some background compression to make the subject
"pop" - so many recommend a 200mm equiv. lens as a modern
internally focusing 100mm actually becomes 80mm focal length at macro
distances.
- for AF, consider:
- Canon:
- Canon EF 180mm f/3.5L macro USM
- Canon 100mm f/2.8 macro USM for Canon (or perhaps the 100mm f/2.0
plus extension tubes)
- Fuji/Nikon:
- AF-S VR Micro-Nikkor 105mm f/2.8G ED-IF SWM
- Olympus:
- ZD 50mm f/2.0 macro and macro of 1:2 - can combine with
25mm extension or 2x TC for 1:1 but not internally focusing.
- designed for Olympus macro flash with adapter
- ZD 50-200mm f/2.8-3.5 has a close focus of 1.2m and macro
of almost 1:2 when using 200mm (ie. 400mm eq.)
- ZD 70-300mm f/4.0-5.6 is a cheaper alternative and gives
1:2 macro
- Sigma 100mm f/2.8 macro
- if you are wanting to use a legacy macro bellows system such as that
made for Olympus OM:
- be aware, you will most likely need a 7mm extension tube as well to allow
adequate clearance when mounting the bellows, otherwise the bellows may
hit against the camera's flash eg. Olympus dSLRs, Canon EOS dSLRs
- using the OM bellows on Canon EOS:
Introduction:
- macrophotography is photography using magnifications of around 1:1 (ie.
subject area is same as film or sensor area)
- the term is usually applied to a range of magnifications from
half-life size (1:2) to about 5x magnification (5:1) which on a 35mm
film camera means a subject area down to about 5x7mm for the 5x
magnification. Higher magnifications are generally the domain of
microphotography and use of microscopes.
- most "macro" zoom lenses are really just close up lenses and
only allow magnifications to 1:4 or 1:3 (ie. 1/3rd life size)
- traditionally with 35mm film photography which has a film size of
36x24mm, this means that the lens system can allow focus at least to a
field of view of that same size (ie. 36x24mm) and perhaps even smaller.
- for simplicity, when talking of magnifications, it is probably least
confusing to use this as the standard rather than use the size of the
digital sensor, although the latter is perhaps more correct technically.
- the main aspects to look at in a macro system are:
- magnification - does it suit your needs of magnification
- this is dependent on both the closest focus point and the lens
focal length
- depth of field:
- macro work usually results in very narrow DOF which mandates using
the smallest apertures such as f/16 to show your subject fully sharp.
Smaller apertures risk image degradation due to diffraction effects.
- software base depth of field
adjustment:
- Helicon
Focus - automatically stacks images taken with different
focus points to generate an image with much greater DOF.
- working distance - how close do you need to get to the subject
to achieve that magnification
- this is dependent on the effective focal length.
- the greater the working distance:
- the less chance of scaring a live subject
- the less chance you will have of getting pollen, etc on your
lens
- the less chance you will have of being bitten by your subject
- the more flexible the possibilities for lighting the subject.
- but unfortunately, the flatter the lighting will be with on
lens twin light flashes, thus you may need to resort to more
cumbersome flash setups, thus the Canon MR24 twin flashes will
not be as effective mounted on an EF 180mm macro lens as they
would be on a 65mm or 100mm lens.
- image quality
- has the lens been optimised for close focus
- has the lens been designed for a flat field - in other words, does
the point of focus make a flat plane parallel with the film or
sensor rather than being a curved plane which would put the edges of
a flat object out of focus.
- ease of use:
- for live subjects, ease of use becomes very important.
- manual focus and manual lens stop down takes much longer and you
may miss your shot if subject flies away, here AF may have an advantage,
although in general, AF is more of a hindrance in macrophotography.
- using a reversal mount requires adjusting subject distance for
focus and requires you to press the lens DOF button to achieve
stopped down apertures during the exposure.
- using extension tubes for manual lenses may require you to press
the lens DOF button to achieve stopped down apertures during the
exposure.
- the BEST combination for live subjects without flash would be either:
- the Canon 1Ds Mark III with its live preview (only manual
focus) and low noise at high ISO allowing faster shutter speeds
+ Canon EF 180mm f/3.5L macro USM but you may want to use this
combo with a tripod.
- the Nikon D3 or Nikon D300 with its live preview (only manual focus)
coupled with a Nikkor VR macro lens
- the Olympus
E330 with its tiltable live preview LCD in mode A allowing live
auto-focus and you to not have to
have your eye in the viewfinder with ZD 50mm f/2.0 macro.
- the Olympus E3 with its tiltable live preview LCD for MF and
built-in IS for ANY lens eg. OM macro lens or ZD 50mm macro.
- tilt lens for adjusting plane of focus:
- these are manually focussed and manually adjusted lenses but not
easy to use
- consider the Nikon as it can be used on either Nikon, Canon or
Olympus dSLRs.
There are several ways to achieve macro
photos:
- add a close-up filter or macro adapter onto the front of your
existing lens
- generally this will give you the worst quality but it may be your
only option with cameras with fixed lenses or those on a limited
budget.
- with the main lens focussed at infinity, adding a close up lens
will allow closer focus depending on its diopter value:
- 1 diopter => 1m
- 2 diopter => 0.5m
- 4 diopter => 0.25m
- When the main lens is focused at its closest normal focus point
these distances are somewhat reduced. Maximum magnification depends
upon the focal length of the lens in use.
- these simple lenses introduce some astigmatism and distortion
that is directly proportional to their power, it's best to stop the
lens aperture down by 2-3 stops (say from f/2.8 to f/8) when
shooting with close-up lenses, especially those with higher diopter
numbers.
- Rules for stacking close-up lenses: Place the highest-power
lens closest to the camera lens, then the next highest, etc. and
avoid stacking more than two close-up lenses if possible.
- A minor downside is that your camera won't focus to infinity with
a close-up lens in place.
- LMScope high quality macro/micro adapter fits onto almost
any lens of focal length 20-90mm via a step down adapter to its 37mm
thread:
- add an extension tube or bellows between the camera body and
your lens.
- this will give better quality, but you need to increase your
exposure a little as your effective f/ratio increases, for example
adding a 25mm extension tube is approximately equivalent to 1
aperture stop down in exposure, and putting a OM 50mm macro lens at
closest focus (equiv. to 25mm extension tube in itself) which adds 1
stop in addition to the 1 stop of a 25mm extension tube.
- In the old days you had to manually calculate this effect (and
still need to today if using a flash that doesn’t have TTL
control) but with TTL metering the camera automatically allows for
this.
- a minor downside is that your camera won't focus to infinity with
an extension tube in place.
- for Canon EOS SLR’s the only bellows that works is a third party
bellows made by Novoflex and very expensive!
- an extension tube may also mean that autofocus capability is no longer
possible and with some lenses focus is not possible (such as fisheye
lenses)
- see macro extension tubes for
more information.
- use a lens optimised for close up work (ie. a macro lens not a
macro adapter)
- this will usually give the best quality if it is a good macro lens.
- combine 2 and 3
- this will usually give the best quality and the highest
magnification.
- add a teleconverter:
- although this does not allow you to focus closer, it will increase
your magnification at a cost of effective aperture and optical
quality.
- a 1.4x teleconverter will cost 1 F stop in exposure as with a 25mm
extension tube on a 50mm lens, and have the benefit of maintaining a
good working distance while the extension tube provides in effect a
2x magnification but requires closer working distance.
- if you are using a Canon EOS 100mm macro lens then normally you
cannot put Canon’s 2x or 1.4x convertors behind it because the
Canon convertors only work with longer focal length "L"
lense. To solve this, put a small extension tube between the lens and
the convertor
- reverse your lens:
- this can be done in one of 2 ways:
- purchase a special reversal mount for your SLR mount which
will have a male filter thread on it of a given size which will
allow screwing a lens onto it back to front
- a 50mm standard lens for 35mm cameras when used on the 2x
crop Olympus E-digitals in this way will give a subject
image of about 22x28mm at a working distance of about 10cm.
- shorter focal length lenses will give greater
magnification but shorter working distances
- the 21mm Olympus OM Zuiko gives a subject area of only
5x6.5mm on the Olympus E-digitals
- you must manually press the lens DOF preview button to stop
down the aperture during the exposure - luckily, the Olympus OM
lenses have a DOF preview button
- focus is not changed much using the lens focus ring and thus
you must alter camera to subject distance to achieve focus.
- special problem with Canon EOS lenses on Canon EOS bodies:
- this can only really be done through the Novoflex
reverse adapter which maintains the electrical
connections between the lens and body, but is a
relatively expensive solution.
- purchase a special male-male filter ring adapter which screws
onto your normally mounted lens and allows a second lens to be
screwed onto it back to front.
- this is similar to using a close up lens on your main
lens.
- Magnification ratio is calculated by dividing the focal
length of the normally mounted lens by the focal length of
the reversed lens (i.e., when a 50 mm lens is reverse
mounted on a 200 mm lens a 4:1 magnification ratio is
achieved).
- The use of automatic focus is not recommended due to the
extra weight of the reverse-mounted lens.
- The diaphragm of the reversed lens is kept fully open in
this mode so it doesn’t matter what sort of lens it is
- A big advantage of all supplementary lenses is that they
do not affect the effective aperture of the main lens.
- the main problems here are that:
- it leaves the rear lens exposed and
vulnerable to damage
- you cannot use AF
- in general, best results would be had by using a manual focus system,
unfortunately, there is only a couple of digital SLRs optimised for accurate
manual focus with Live Preview for macrophotography including the Olympus E330
, Olympus E510, Olympus E3,
new dSLRs from other makers made in late 2007 onwards with live preview..
