The center is certainly sharper than the corners wide open. The famous vignetting is not a problem at all AFAIC. The corners are all about the same sharpness. If I were splitting hairs, I might ding the left side a tiny bit, but it's nothing that will affect normal photography. Lr CC 2015.6, defaults except for Exposure boost, WB Daylight.

Thanks for the test Jim. I think the left side is definitely soft compared to the right. Hard to tell from the image though. I'd bet if you shot buildings or something with hard lines you find the left side stands out. Based on my experience though that's a decent copy with a "normal" slightly softer side.

i think that it's worse than slightly soft, but how can anyone tell with such small pics... were they downrezzed, 100% partial crop, or ?? did the raws get touched by sony in-camera corrections? etc.

flip side is that it's a tough test because it's a landscape that was shot wide open... does the left side clean up at any aperture? well, maybe not: "As you stop down there is very little change. The center improves a little to excellent levels but there is next to no improvement outside of the center. So at typical settings for landscape use, e.g. f/8 or f/11 other much cheaper lenses are sharper in the corners. The Canon FD 2.8/35 for example." http://phillipreeve.net/blog/review-carl-zeiss-sonnar-fe-2-835-za-t/

there was a thread on fredmirada(?) where several people were complaining about shooting landscapes with this lens.

Is my face red! The camera was set on APS-C crop, and I never noticed. I'll repeat the test tomorrow.

Jim

How funny.  Maybe I should test in APC-C mode?

When you do a test through in a level shot as well.  The tilt throws my brain off.
