Perhaps against my better judgment I went for a 3rd copy. This time, it is very close to being right on at all focus distances with a +5 MFA. The only problem is that it front-focuses by a few millimeters at MFD. For example, if I take a close-up of my toddler's face and focus on her eye, her eyebrow and bridge of her nose will be sharp, but the eye will be slightly OOF.
I don't take close-ups of the face with a 35mm lens very often, but I'm still irritated by the fact that it consistently front-focuses at MFD. I'm going to try increasing the MFA to +8-10 today and see if that can solve the FF problem at MFD without causing a back-focus problem at other focal distances.
Question: is this the sort of problem that Sigma could fix if I sent the lens and my 5D3 to them? It's frustrating to be so close to finally having a good copy of this lens. When it hits, which is most of the time, it's just as amazing as everyone says it is.
