Originally posted by Emacs Did you think 15Ltd is optically perfect? No of course, nowhere near that. It is field curvature: want sharp center — will get soft edges. Want good edges: center won't be as sharp as it could be. 31Ltd is much better in this aspect, as well as 77Ltd.
I think that Limited lens should have outstanding IQ. That true for most FA limited lens, so I believe that it's true for all limited series.
I use my FA31 for landscape photo primarily, and sometime I need wider lens, but can't find anything with outstanding IQ like FA31. So sad to see IQ of DA15 that I want to buy in future for the same goal as FA31...
Why people buy 15lim?
Manual focus doesn't matter much for photo with infinity focus, so I looking for all cases... Do you try Zeiss lens, what about 18 or 21?
