p.1 #1 · p.1 #1 · Sony A7R with UWA Zeiss ZM 21mm f4.5


I did some searching for this and scoured Google as well. I did see the UWA RF lens on A7/A7R thread, but did not see any results regarding this lens in particular.

I am close to purchasing one through FM and would like to know if anyone has some results on how the A7R sensor handles this lens in regards to color casting and edge/corner blurring. Any other comments are also appreciated.

Thanks!

I sold it before the a7's came out, but I've tried it on an M8, M9, NEX-7, and Ricoh GXR. It was fantastic on the GXR, but on the other three, about a central third of the image wasn't impacted by blur and color cast, so I wouldn't hold out too much hope.

I doubt very many people have tried. It's one of the most symmetrical 21mm designs out there.

I have this combo. The color cast is terrible, but the smearing is not that bad actually. Definitely one of the better RF-a7r combinations.

I'm curious, too. I have A7 + Contax G21. Although the color shift can be fixed, I'm not too happy with the edge sharpness. What's the best UWA lens on A7/A7R under $1200?

This is good to hear before I pull the trigger. Maybe I'll just go try it out.

Btw, when I did this I was focusing in the corners, so take this with a grain of salt. But people tend to discount this lens because of the color cast, but in my view it is not too bad, certainly better than the 2:8 vrsion or the skopar

I think the 21/1.8 ultron is the rf champ on the A7s. Michael S has examples.

Other good examples are the Canon FD 20/2.8 and the Contax Zeiss Distagon 18/4. Approved by me
Olympus OM 21/3.5 looks good as well but I never used it. And not to forget Samyang 14/2.8.

Thanks for the suggestions. I'll look into them. How does the Distagon 18/4 look on A7? Not too big, is it?
