Four Thirds lenses
introduction
Four Thirds lens accessories
EX-25
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:
with ZD 50-200mm II:
see
Four Thirds.org for further details on focus range when used on various lenses
EC-14
EC-20
Olympus Super-High level pro lenses
Olympus ZD 7-14mm f/4
-
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 my photos using the 7-14mm:
Olympus ZD 14-35mm f/2.0 SWD
-
equiv. field of view to a 28-70mm lens
-
world 1st standard zoom with f/2.0 throughout zoom range
RRP $A3499
-
seems that some models have issues with gaining AF lock in low light with the E3:
Olympus ZD 35-100mm f/2.0
-
released in 2005, it is the world's 1st lens to give f/2.0 over the entire zoom range
a much loved lens for videographers as it is constant f/2.0
now this would make a brilliant available light portrait lens with nice bokeh ~$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;
-
Olympus ZD 150mm f/2.0
-
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

Olympus ZD 300mm f/2.8
Olympus ZD 90-250mm f/2.8
-
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.

Olympus High-level pro lenses
ZD 11-22mm f/2.8-3.5
ZD 12-60mm f/2.8-4.0 SWD
-
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:
AF fault identified in those with serial numbers between 230005416 and 230010688 - see free inspection & repair

RRP $A1499

mark I
mark II
ZD 50-200mm f/2.8-3.5
non-SWD original version
Olympus macro flashes can be attached via the bayonet method
nice lens but some vignetting wide open; good bokeh; ~$A1400;
1.07kg; 67mm filter; close focus 1.2m;
-
-
SWD version
no longer allows the macro flash to be attached
similar to older model but adds faster SWD autofocus and improves color blur property
157mm x 87mm / 6.2 in. x 3.4 in.
1.07kg / 2.4 lb (with tripod plate)
filter 67mm
16 elements in 15 groups, including 3 ED elements
7 rounded blades
see some of my photos with this lens
matches beautifully with either the TC-14 or TC-20 teleconverters
RRP $A1599
-
ZD 8mm f/3.5 fisheye
ZD 50mm f/2.0 macro
-
a brilliant diffraction-limited lens with almost no aberrations
this is one lens you should have for portraiture, general use and macro work - I bought one.
hopefully Olympus will update this with a new SWD version with a focus range limiter switch to improve its AF performance.
alternatively, OM macro lenses for really close macro work where manual focus is preferred anyway.
~$A850

Panasonic Leica-D lenses
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.

Sigma lenses in Four Thirds mount
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

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.
