So, new camera, new tests. I got an a6000, mainly for photography, and I have several options to choose from in my lens set, so, let's see how good each one is.
As usual, just as important as these sharpness tests are my bokeh tests.
The contenders are:
Vintage Leica-R lenses (super nice, but bigger than I want for this body):
* Leitz Elmarit-R 24mm f/2.8 (1978) (Leica R)
* Leitz Elmarit-R 35mm f/2.8 (1978) (Leica R)
* Leitz Summilux-R 50mm f/1.4 (1976) (Leica R)
* Leitz Macro-Elmarit 60mm f/2.8 (1983) (Leica R)
* Leitz Elmarit-R 90mm f/2.8 (1966) (Leica R)
Vintage lenses for mounts with short focal flange distance:
* Industar-61 52mm f/2.8 (1969) (M39)
* Kodak Anastigmat 50mm f/1.6 (~1947) (S-mount cine lens)
Modern lenses with AF:
* Sigma 19mm f/2.8 (E-mount APS-C)
* Sigma 30mm f/2.8 (E-mount APS-C)
* Sony 50mm f/1.8 (E-mount FF)
The Kodak has a strong vignette when used on APS-C, but it's almost gone when doing a 16:9 vertical crop. It's very soft in the corners, but corner sharpness is not why I got it: this lens has a crazy image rendition, with super weird swirl bokeh. I will post about it eventually.
I'm very happy with the results: the Sigma 30mm and the Sony 50mm are doing great, and the Sigma 19mm is not so sharp in the corners but still nice overall. And comparing these lenses on the a6000 with what I have on the Canon 5D mark II (scroll to the very end to see that comparison), I think I'm seeing an improvement! It turns out, newer APS-C is sharper than older FF, both in the center and in the corners. And bokeh is reasonably good in these E-mount lenses too! Plus, they are small and cheap, and so is the body. I can't push up the ISO as much on the a6000 as I did on the 5D2, but I really like my new stills setup.
The Industar is cheap and small but can't be the star of the show. The Kodak is super sharp in the center but incredibly soft in the corners. Which is perfect for what I intend to shoot with it: portraits with a centered composition.
The Leicas are still doing great, particularly the 35mm, 50mm and 90mm, but they are too big for what I want on this body.
