Re: Strange front-focusing problem with Sigma 35/1.4 | |
Well, for what it's worth I think my 5D3's AF is probably fine, and the issue was entirely with the Sigma 35/1.4. I just got my Canon 50/1.4 back from Canon Service, and they acknowledged that the lens assembly was broken and replaced it. That was one of the other lenses I was having issues with, in addition to a Sigma 85/1.4 which has already been returned.
Here are a few 100% crops from the 50/1.4. Again, just some light capture sharpening applied in LR4.
