I have the Sigma 50mm, f/1.4, and thus far haven't really had the time to play with it. Yesterday I took some pictures and I noticed some focus issues on the pics. I tested it out this morning, and these are the results:
Test using LiveView:
Test using ViewFinder:
I think I see a problem. Does anyone agree, not agree? And, if there is a problem, how do I proceed? I tested my Nikon 14-24mm, Nikon 24-70mm, Nikon 80-400mm, and Nikon 105mm lenses as well, and though I do see some differences when magnifying to say 400%, it is nowhere as obvious as with the Sigma 50mm. Hence I think it is just the Sigma lens / Nikn D800 combination. Should I talk to Nikon or to Sigma?
