| p.1 #10 · Contax Zeiss 28mm f2 and ZE/ZF |
What was the focus point in this last test? The box looks sharper in the CZ image but the metal parts (hinges?) look sharper in the ZF image. There are probably some differences in field curvature complicatating the comparison.
Could be, the focus was live view on the zeiss logo in both cases. I'd find it difficult to see field curvature being that different when the basic lens design is the same. I think the ZF has different coatings. Of course Zeiss just lump it all under T* and it would be great if they differentiated a bit.
The ZF was slightly cooler overall, light transmission was pretty much the same. I just found the ZF to show more aberrations. The magenta bloom i always though was sensor generated but in this case same sensor. The ZF is sharper, wide open anyway. I found the CZ a little less precise, which for me i think i prefer.
I'd love to find someone locally in Kent with ZFs to compare. I've agonised over whether i should sell up the CZ and go down ZE/ZF. These are primarily used for filming, so i'm getting the declicked etc,. but it's always a risk with old lenses that have histories you cannot confirm. Also there are some ZE/ZF lenses i'd really like - the 50 macro planar for example and the 25 f2.
ALthough then i think i'm just being greedy...
If you want to see some really weird results i should show the comparison between a 28mm f2.8 distagon and a Zeiss ZA 24-70 f2.8 zoom. The Zoom has less depth of field, noticeably so.
