Sigma 35mm f/1.4 DG HSM Art

I have gone through several copies of this lens, first with my Nikon D600 (went through 6 copies), and now with my Sony A7 and the a Sony A Mount. All of the Sigma 35mm's I have tried have had AF accuracy issues, especially between the 2m to infinity focus region.

I have the Sigma USB dock and it doesn't help much because the way the lens focuses near the 2m mark is very different from how it behaves near the infinity mark.

The outer-most focus points on both the Nikon & Sony mounts back focus massively and this particular issue isn't fixable via the USB dock.

I truly have a love/hate relationship with this lens and I would happily pay twice the cost of this lens just to have a solid working copy.

Here is a post I have written about my issues with the lens.
