I have to say...I think that half of the people here complaining about the focusing of the 35mm f1.4 Art. Mine focuses spot on ...all the time and I just LOVE the lens. it's one of those lenses that just stuns you every time you open the files. In actual shooting situation my lens is very consistent.
+1. I didn't even think I'd like a 35mm lens on a FF body. I bought the 35mm Art as an impulse at Christmas because I got tired of waiting for the 50mm. I have to say, I love this lens. The AF is very accurate, and the colors are vivid, and it is razor sharp. Also, the field of view is very versatile, and it is nice to have so much DOF at f/1.4 compared to a longer lens like a 50mm or like my 85mm (at f/1.. The thing lives on my camera.
Ah...yes...photographers..not peepers...ahhhhh...I may eventually buy the 50mm and a dock...I want to see Dustin Abbott review both first. I hope that that can happen. Until then I am loving my original Sigma 50mm!
35mm is CLASSIC on a FF for all the reasons you mentioned and the Sigma Art is a classic, too!!!
