My A7 just arrived. Initial RF impressions (after experience with NEX-7, NEX-6, 5Dm2 as recent cameras):
Leica 24 Elmar (on Fotodiox): Very slight color shift. Slight vignetting. Smeared corners/edges which clean up by f/8 for the most part. Jury still out, but certainly usable. Edges very weak vs M9.
Leica 35 Lux FLE (on Fotodiox): Nice! Vignettes a fair bit at 1.4 and 2.0; tiny vignette at small apertures. Possibly very tiny color shift at widest apertures (I don\'t think so, but not 100% sure). CA at f/1.4-2.0. Soft perimeter at 1.4-2.0 (which is fine by me). Almost ZM 50 Planar-like at infinity and f/4. Extremely sharp at 5.6 (tiny perception of softness in extreme corners). Pixel sharp to corners at f/8. No need to LCC correct -- vignette adjustment works fine.
Contax g35: Nice! Light vignetting at 2.0-2.8 but no color shift. Very soft mid-zone at 2.0, and still soft corners at 2.8. Sharp at f/4 to edges; Very sharp to extreme corners at 5.6, 8. Sharper than on APS-C NEX-7 for some reason.
OM 24/2.8: Works fine like on any DSLR. A touch soft in corners; central frame razor sharp. Corners look \"1970s sharp\" at least at 5.6 and 8. Not quite the g45 or ZM 50/2, but really solid after 2.8.
Zeiss ZM 50 Planar: A beauty! Tiny vignetting (not sure if same in M9). No shift. Mostly sharp extreme corners at f/2. Very very sharp by f/4 (I\'m picky). Every pixel looks like center pixel at f/5.6+. Not sure it could look better on any camera. p.s. - something obviously wrong with those early Shanghai samples...
Well, those are the early returns. I still have the CV 50/1.5, g90, and various SLR lenses to try. Overall, I\'m extremely happy. The 24 Elmar was a long shot, and I intend to work a bit more with it, but it\'s really the only disappointing lens I have.
Great info. The G35 performance bodes well for the 35 Summicron IV, which has similar characteristics and is also small.
I would think so. It\'s definitely a bit funky at f/2 (especially the OOF areas), but certainly looks pretty solid overall. We have horrible haze and overcast today; I\'ll try to put a few infinity shots up once things clear up...
The corner sharpness at smaller apertures is better at longer distances...
Thanks. That\'s about what I would expect from the 35 IV Summicron, too. It looks good. Those corners do look blurry, but my expectations are probably a little skewed from the RX1. The 35 IV wasn\'t perfect in the corners on the M9, either, if I remember correctly.
p.s. here are the (very similar) mtfs and designs for the G35 and 35 Summicron IV. I wouldn\'t expect the corners to be super sharp, judging by these:
