Olympus m.ZD 75mm f/1.8 lens


  • released in July 2012, this 75mm micro Zuiko Digital lens is an awesome lens for Micro Four Thirds system
  • it is be optimised for video as well as still and thus have fast, near silent AF with Olympus' MSC designation.
  • the combination of 75mm and f/1.8 allows nice shallow depth of field imagery with lovely bokeh and this lens is incredibly sharp wide open!
  • combine this lens with the Olympus OM-D E-M5 camera and you get 5 axis 5EV image stabilisation and f/1.8 aperture with a more usable DOF of a f/3.6 lens - an awesome combination indeed!
  • it will finally resign my Samyang / Rokinon 85mm f/1.4 lenses and my Canon pro gear to the cupboard!
  • my favorite lens for 3/4 body-length outdoor portrait shots where the background is nicely blurred is the Canon 135mm f/2.0 lens on a Canon 1D Mark III 1.3x crop camera shot at f/2.5-2.8 to give just enough depth of field (DOF).
    • this equates to 176mm f/3.3-3.6 on a full frame camera or 88mm f/1.8 on a Micro Four Thirds camera, so the 75mm f/1.8 comes very close to my ideal lens for this type of shooting, plus you get the added advantage of image stabilisation on Olympus cameras and the wider f/stop, for lower light conditions when shooting in the shade or at flash sync when using flash fill-in, which can be very handy.
    • the 75mm shot wide open at f/1.8 on my E-M5 is even SHARPER than the excellent pro 135mm f/2.0L lens when shot at f/2.8 on my Canon 1D Mark III and much sharper than it when shot at f/2.0 at 1/400th sec!!
    • Now if only Olympus made an adapter to allow their ring flash to be attached as a fill-in flash - in the interim, I would have to resort to a Canon Ring Flash with a 58mm filter thread adapter and manual flash exposure, but with a hotshoe adapter without the extra TTL pins, I could push the Olympus OM-D E-M5 camera to fast flash sync speeds of 1/500th sec with some flash cutoff, but still very handy in sunlit situations.
  • the lens will give similar imagery in terms of field of view and depth of field as a 150mm f/3.6 lens on a full frame camera - not far off the professional's full frame workhorse lens specs of a 70-200mm f/2.8 lens when used at 150mm.
  • thus it will give similar FOV and and only half a stop more DOF to:
    • a Canon EF or Nikon G 70-200mm f/2.8 lens at 150mm mounted on a full frame dSLR
    • a Leica-S 180mm f/3.5 lens mounted on a Leica S2 medium format dSLR but at much less than the $35,000 this kit costs.
    • a Hasselblad HC 210mm f/4 mounted on a Hasselblad H4D double-35mm medium format digital camera
  • the well corrected astigmatism, vignetting, distortion and its sharpness wide open, could mean this lens could be a fantastic lens for astrophotography, similar to how the Canon 200mm f/2.8L lens has been to Canon users although the field of view will be substantially wider.


  • 75mm f/1.8 = 150mm in 35mm terms
  • close focus 0.84m = 0.1x macro with image coverage of 173x130mm
  • “ZERO” nano coating
  • 58mm filter thread (non-rotating)
  • high speed, silent focusing with MSC lens drive technology
  • precision manual focus ring but no focus distance scale
  • internal focus
  • 10 elements in 9 groups
  • 3 ED and 2 HR lens elements
  • 9 rounded blades
  • lovely smooth bokeh
  • apparently, correction of astigmatism is almost perfect, contrast and resolution across the frame is excellent
  • 63.5mm diam x 69.5mm long
  • 305g (10.8oz)
  • $US899, $A999
  • optional LH-61F metal lens hood - attaches with an outer friction knob system that allows attachment or removal even when the lens cap is attached
    • no bayonet lens hood mount
  • optional LC-61 metal lens cap

image quality would appear to be significantly better than the very sharp Olympus m.ZD 45mm f/1.8 portrait lens and almost as good as the superb Olympus ZD 150mm f/2.0 super telephoto lens
