#2 appears to me to have a fair amount of tilt to it. The pinecone along the right edge of the frame appears to be reasonably in focus; the left side of the frame appears to be in focus much closer to the bottom edge. It looks like this is also the case in #1. Of course, the subjects I'm looking at aren't positioned symmetrically and I'm not looking at the full resolution image, so I could be wrong. :-)
While this lens is supposed to--per the MTF curves--drop off considerably in the corners, I wouldn't expect to see this kind...Show more →
I checked in PhotoShop, scrolled from pinecone to left edge (staying same vertical level), and it seems that sharpest area is about 20-40pixels lower on left, which I would assume is correct due to right side being 20cm/8inch higher and therefore little closer. Check also how the cross on right top corner is in focus, that is my real concern. Nothing in left top corner is in focus as it's much further away.
I can test tilting separately, but A7r and this adapter was OK with 28mm Leica, in my A7 there is slight tilt. Tilting in these photos however isn't anything I'm concerned about, just the field curvature.
EDIT: Oh, crap, checked MTF - stupid fault, should have checked before purchasing...can't understand how Leica puts their name to this kind of lenses...
so this behavior is as expected, clearly field curvature is extreme in corners.
EDIT2: And these are Leica calculated MTFs, not comparable to Zeiss style, which are based to real measurements. So real performance is worse than these MTFs make it look like.
