The Sigma 35 1.4 lens is a phenomenal lens. It is sharp wide open and just handle beautifully, in fact on my D3S it is very sharp using every focus point. UNTIL... I attached my SB-800 and then all of a sudden I have OOF issues, back focus and front focus issues. Which focus issue I have varies on the distance of the subject and even then it is inconsistent. Sometimes it may front focus, then OOF then back focus.

I have tested handheld, and on a tri-pod. When hand held the shutter speed is @ 100. The issue is worst from f/1.4-f/4 then it gets better but the image is soft compared to not using my SB-800.

Has anyone else experienced this issue?

Thanks!!
