Hi,
I would like some advice on the Schneider pc super angulon 28f2,8...
Dors anyone tried it on modern sensor? What's your feeling?
Ca?distorsion?corner sharpness?
I have one and have used it extensively with my A7R and before that, a Fuji X-Pro 1. (FWIW, mine was converted to a Nikon F-mount using a Leitax replacement mounting flange and a Kipon adapter and tolerances being what they are, other combos may work better or worse than this one.)
In general, I've been very pleased with the results from my copy, although I'm not a reviewer, so I can't answer your specific questions about its performance. I can say it provides a noticeably different "look" than the Contax N lenses I also use, but not one that's necessarily better or worse. This is specifically true with regard to contrast, as it doesn't "pop" the way the best Zeiss glass, but renders scenes in a softer, smoother style that, for some subjects, is preferable. (To that end, I do find that I punch up the overall contrast a bit during post-processing; not a lot, mind you, but more than I do with my Zeiss lenses.)
I photograph primarily at night and my primary subject matter could loosely be considered architecture. I usually shoot at f8, but sometimes f5.6 and f11, and while there is some distortion, it's nothing I haven't been able to sufficiently correct using the basic distortion tools in Photoshop. Here are a few samples from my project "85258," which involves photographing my neighborhood at night, the first set being taken with my Fuji X-Pro 1 and the second set with my A7R, so you can judge for yourself how much residual distortion remains:
And with the A7R:
Incredibly, I don't think I've ever used it during daylight or processed any photos from it in color, so I don't know if any of the above is helpful to you. But as I said, on the whole,
I am pleased with its performance and for what I paid for mine (IIRC, it was right around $1k back in 2012), it represents more than fair value (IMO, anyway.)
Hope this helps!
