Pros: Construction, general yield (macrocontrast, colours, resolution), field flatness at medium-long distances (ZF2 2016), short minimum distance of fire for effects, manual focus well calibrated (duration, play, precision with serious bodies).
Cons: Light in the ZF2 (strong in ZF) bending of field at court distances, awkward automatic lock of the aperture ring F/22.
Opinion: I took after a long time a ZF. 2 25/2.8 New newly built, on sale, to complete the Zeiss outfit for D700, A7r and NEX 5n, as well as on film. I also have the ZF 28/2 as a close focal and I have or have tried so many other Nikkor, Voigt, Zeiss ZF and ZM, Leica R. Forget the buffal that run on the Internet, I was worried about field curvature and more, but I knew from the Zeiss Professional datasheet and the fame in lab that this ottic A is the most resolvent wide ZF f/2.8 (more than 21 ZF/milvus). To increase it in almost non-photographic applications would have to jump to milvus 25/1.4 and only above F/3.5, with very little stuff in focus. The series that I took has perfect calibration to infinity (curvature Overorretta, not undercorrected as they say around, slight bowing of the focal plane towards the photographer at the edges, then aligns on the corners) and the curvature of the field remains flat up to less than 2 m, Then it makes no sense to measure it in normal use, rather it is slightly better than the ZM 25/2.8 on Sony and Zeiss Ikon. Compared to that Biogon, this ZF. 2 is easier to use in digital, it is more uniform as a field rendering with blurred less brutal to the edges, but it is more distorted and does not have the extreme sharpness tips of the ZM. Excellent for mixed applications and video footage, I prefer the ZF 28/2 in interiors (with the CRC) and the ZM 25/2.8 for Architecture/outdoor travel (in the area close to the focal plane beats the Fuji X 23/2 on APS focused in full). This ZF 25/2.8 had the same recarature as the ZF. 2 18/3.5, which is now more than a match with the same 21/2.8, thanks to the best overcurrent profile of the field curvature. Another Nikkor supplanted... not to go back... |
