Olympus ZD 7-14mm f/4 lens


  • rectilinear ultra-wide angle zoom with field of view as for 14-28mm in 35mm terms
  • 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.
  • now that Olympus are selling their brilliant Olympus mZD 7-14mm f/2.8 PRO lens, this Four Thirds lens is likely to find little use EXCEPT if one can add in a ND 100 or ND 400 filter inside a Four Thirds to Micro Four Thirds adapter which would allow bright sunlight long exposures which would give it a potential significant advantage over the new lens
    • hopefully some enterprising company will make such an adapter with in-built ND400 filter
    • in the interim, it may be possible to cut a Cokin ND100 P155 filter (if you can find one as it seems Cokin may not be selling them anymore) to fit suggly inside the odd-shaped interior of an Olympus or Panasonic adapter without having any light leak.
