I just ordered the ZF 35 f/2. The crop factor brings it up to a 50 mill. Great standard lens; light, fast and sharp.
I wish there was ZF ultra wide.
There is now: the ZF 18/3.5. I just received an evaluation unit a few days ago. Some initial impressions are posted in my August 22 blog and I'll have more coming, as well as a full writeup in my Zeiss ZF Lenses review (covering all 8 ZF lenses). To be clear: I am not a RED user or cinematographer (yet!).
Image sharpness and contrast is very high, and for the RED camera, shooting wide open at f/3.5 should yield outstanding results, based on what I'm seeing so far.
Vignetting is strong (2+ stops on full frame) and could be an issue even on the RED; f/5.6 still shows some vignetting on full-frame, f/8 is needed for even results. I think part of the issue is the sensor, so results could vary by camera (I tested on the Nikon D3).
Alas, flare (ghosting) is disappointing compared to the Nikon 14-24--just don't let direct sunlight strike the optics. However, veiling flare is essentially non-existent with the typical Zeiss contrast.
Color rendition seems consistent with the other 7 ZF lenses, which seem to be perfectly matched, much more consistent than the Canon and Nikon lenses I use. To be fair though, Nikon and Canon have both changed their coatings over the years, so one can't expect the same results for lenses made 20 years apart.
Another interesting "change" with the 18mm is that its focusing seems to be the nicest of all the ZF lenses (I have the full set). I don't know if Zeiss changed the lubrication or it's just the copy I have, but the 18mm is really smooth and nice focusing. In practice perhaps it won't matter as the other ZF lenses are also excellent, but it does seem to be a bit smoother, with a bit less resistance than the rest of the ZF line.
