Here is an interesting survey of still lenses. It looks a little dated, I don't see any new Zeiss ZF/ZE's, but it's still a very compelling resource. I've come across if various times, thought I'd finally share.

It was very useful to me once when I was comparing old Leica's, Nikons and Zeiss's.

It's a compendium of opinions, based on photographers inputs, of a vast lineup of lenses from these manufacturers:

CANON Eos, CANON FD, NIKON AF, NIKON AIS, LEICA R, ZEISS, MINOLTA, OLYMPUS, PENTAX, VOIGTLANDER, etc


STILL LENS SURVEY: CANON, ZEISS, LEICA, NIKON, and more
