• Four Thirds lenses are those designed for the Olympus Four Thirds dSLR system and can be used on Micro Four Thirds cameras via an adapter, although on some bodies, AF may not work or be slow.
• Panasonic initially made some very nice Leica-D optically image stabilised lenses for Four Thirds but have since apparently abandoned the Four Thirds format to concentrate on the extremely popular Micro Four Thirds format.

• 25mm extension tube for closer focus capability
• AF is maintained when used with the ZD 50mm f/2.0 macro but AF may not be possible with most other lenses
• AF will probably NOT be possible when used on Micro Four Thirds via an adapter
• examples of use on a Four Thirds dSLR:
  • with ZD 14-54mm II:
    • need to set lens to 54mm, auto focus is possible from 4.5-5.5cm in front of lens
  • with ZD 50-200mm II:
    • at 200mm, will auto focus from 54.5cm to 175cm from the subject
• see Four Thirds.org for further details on focus range when used on various lenses

• high quality 1.4x teleconverter
• 1 stop less light

• high quality 2x teleconverter
• 2 stops less light

• these are very expensive, weather-proofed, high quality lenses

• see Olympus ZD 7-14mm f/4 lens
• rectilinear ultra-wide angle zoom with field of view as for 14-28mm in 35mm terms
• cannot use filters as very convex glass element
• minimal barrel/pincushion distortion, almost zero at 10mm focal length.
• very sharp;
• performs best at f/5.6-f/8.
• this lens is so good & allows unique creative opportunities, I just had to get one :)
• perfect for indoor work
• seems to have an inbuilt polariser-like effect on blue sky - perhaps the Brewster effect?
• a little purple fringing wide open outdoors at 7mm in high contrast situations at the periphery.
• flare spots if you allow light sources to hit its convex outer lens.

• see Olympus ZD 35-100mm f/2.0 lens
• released in 2005, it is the world's 1st lens to give f/2.0 over the entire zoom range
• a much loved lens for videographers as it is constant f/2.0
• now this would make a brilliant available light portrait lens with nice bokeh ~$US2500 or $A4400
• BUT weighs 1.8kg with tripod lock which is similar to Canon's 70-200mm f/2.8 IS but 1 stop faster.
• 77mm filter; close focus 1.4m;
• SLRgear.com review

• see Olympus ZD 150mm f/2.0 super telephoto lens
• in effect, give the telephoto reach of a 300m f/2.0
• this could be one of the best lenses for astrophotography as well as high-end work if you can afford it
• combined with a TC you get reach of 420mm f/2.8 (1.4x TC) or 600mm f/4 (EC-20)
• plonk this on an Olympus E5 and you have one very light super telephoto system for sports or wildlife use.
• 1.61kg; 82mm filter; $A4300
• SLRGear.com review
• FourThirdsPhoto magazine (pdf):
  • with EC-20 2x TC it is half the price and weight, and faster focus with more DOF than the ZD 300mm f/2.8 but not quite as sharp, and f/4.0 wide open.

• see Olympus ZD 300mm f/2.8 super telephoto lens
• a superb lens for birding, etc but is 3.3kg but it's the only way with any camera system to get 600mm telephoto reach at f/2.8!

• see Olympus ZD 90-250mm f/2.8 super telephoto lens
• a fantastic lens for action or wildlife photography and unique at 180-500mm equiv. f/2.8 but ~$US6000 or $A10,000 and 3.27kg with 105mm filter
• the longest zoom made by Canon is their 100-400mm f/4.5-5.6L IS which weighs 1.36kg but 2 stops slower.
• Canon make a 400mm f/2.8L IS lens but this is 5.3kg while the 500mm f/4L IS is 3.9kg and 1 stop slower.

• see Olympus ZD 11-22mm f/2.8-3.5 wide angle zoom lens

• see Olympus ZD 12-60mm f/2.8-4.0 SWD zoom lens
• equiv. to 24-120mm lens
• perhaps the BEST standard zoom for Four Thirds (and perhaps better than available for any dSLR) giving versatility and AF speed, a 5x zoom while still retaining excellent resolution comparable to the 11-22mm and 14-54mm at the expense of a little more barrel distortion at the wide end.
• some complex distortion at wide angle (thus if doing architecture, consider the 11-22mm lens instead) but overall a superb lens.
• 72mm filter thread, does not rotate on focus; internal focus; macro to 0.25m; 0.58kg;
• would combine very well with:
  • 7-14mm, 50mm macro & 50-200mm SWD - a total of 4 lenses that give excellent quality and a focal range of 14-400mm in 35mm terms plus a macro/portrait lens.

• when compared to the Leica D 14-50mm (see here and open the pdf):
  • very similar performance but Zuiko has less vignetting and better corner resolution wide open at wide angle while the Leica has better corner resolution at wide angle at telephoto.

• this is one lens you should have for portraiture, general use and macro work - I bought one.
• hopefully Olympus will update this with a new SWD version with a focus range limiter switch to improve its AF performance.

• XSM is Leica's ultrasonic motor for quiet AF
• Mega OIS = optical image stabilisation
• the aperture ring on these do not work on Olympus bodies and transient mode IS by pressing the shutter button as on a Panasonic or Leica body is not possible, and the Olympus can't change the IS modes as this is done via menus on the Panasonic or Leica body.

• see Panasonic Leica-D Summilux 25mm f/1.4 lens for Four Thirds
• see some of my photos here

• esentially these are just full frame lenses with a Four Thirds mount and thus not optimised for Four Thirds
• HSM = hypersonic motor for quiet high speed AF and also full time manual focus;
• EX = superior build & optical quality
• DG = lenses for digital and 35mm
• DC = especially designed for smaller digital sensors
• OS = optical stabiliser

• discontinued
• beautiful optics - sharp wide open, low distortion, nice bokeh but slow AF - slower than the Olympus ZD 50mm f/2.0 macro lens, and on some cameras has front-focus AF error issues requiring microadjustment to give sharp AF images.
