Olympus m.ZD 12mm f/2.0 lens

  • a unique lens which is great for travel photography but at $700 is not cheap
  • Canon APS-C and Nikon DX dSLR users do not have a wide aperture 24mm equivalent prime lens available to them for under $1000, not to mention that this Olympus lens effectively becomes image stabilised on an Olympus camera - this gives Olympus users a big advantage over dSLR users who must either resort to ultra-wide angle zoom lenses with slow apertures or very expensive 14mm pro lenses.
    • hand held for static subjects on the E-M5, this lens gives 4-5 stops low light advantage over a Canon 7D using a 10-22mm at f/4 to give the same field of view, and even if they used a super expensive 14mm f/2.8 pro lens, the Olympus would still have a 3-4 stop advantage hand held!
    • a full frame dSLR with a 24mm f/1.4 pro lens will give shallower DOF but still the Olympus may have a 1 stop advantage hand held taking into account better high ISO of the full frame. Of course, the full frame will win hands down with the f/1.4 lens when it comes to stopping subject motion blur in low light.
  • furthermore in optical quality (but not ability to blur the backgrounds) it competes very well with the 24mm f/1.4 pro lenses on full frame dSLRs at a 1/4 price and weight!
  • will compliment the Sigma 19mm, Panasonic 25mm f/1.4, Olympus 45mm f/1.8 and Olympus 75mm f/1.8 brilliantly, giving a very light, compact system of relatively wide aperture primes with 35mm film focal length equivalents of 24mm, 38mm, 50mm, 90mm and 150mm - and all image stabilised with Olympus cameras, and optimised for HD video with the world's fastest AF, what more could one want in a high quality compact system?
