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.
- Olympus Four Thirds dSLR system lens mount
- Super Pro designation
- rectilinear 7-14mm zoom = 14-28mm lens on a full frame
- 18 Elements in 12 Groups, including ED Glass Aspherical Lens, ED Lens and Super ED Lenses
- close focus 0.25m = 0.11x macro
- at 7mm focal length and focus at 1m, at f/4 aperture, all should be in focus from 0.54m to infinity
- at 14mm focal length and focus at 3m, at f/4 aperture, all should be in focus from 1.55m to infinity
- convex front lens means filters are not possible
- lovely metal lens cap which slides on LC-87 (87mm)
- 87mm x 120mm
- compatible with teleconverters
- RRP $2599 but now sells for $1799
