  • Carl Zeiss 35mm f/2 Distagon T* 2/35

    0 out of 10 points and not recommended

    A few comments from someone wondering whether to get the CZ 35f2 while the Euro is low. Lateral CA at f8 is a real headache. I'm not worried about the purple longitudinal CA in the f2 files.
    The VFA charts here show almost as good corner resolution at f2 compared with (disappointing?) f8 performance on both on the D200 and the D3X. I have tried correcting the lateral CA in the D200 f8 files of the VFA charts with PTLens and RawTherapee which seem to work in the same way. The result is not satisfactory because it leaves orange/cyan haloes several pixels broad which can't be corrected. Nikon's in-camera correction for the lens on the D3X seems more sophisticated. Some cyan/purple haloes are evident, but the combination is pretty good if you can afford it.
