I know this is a tough thing to answer, but what's your opinion on the performance and value of the Sony/Zeiss 24-70 f/2.8 zoom?
I'm primarily a landscape guy, so I'm looking for corner-to-corner resolution, primarily between f/8 to f/16. Maybe sometimes f/5.6, but not too often.
I have what I think is a good copy of the Tamron 28-75/2.8 zoom; I tried two of them and kept the one that was noticeably better. I rented a ZA 24-70 for a long weekend last fall and wasn't blown away by it, but it might not have been enough time to learn the ins and outs of the lens. I do think I got the AF adjustment pretty well, even on the rental. Unfortunately I'm now starting to get even more neurotic about image quality -- which to my mind is a combination of resolution, color separation, and micro/macro contrast.
Can anyone offer any thoughts?
