Here's latest AF tune I've made to make AF "usable" at distances from 0.28 up to 3-5 meters. Above that pictures get out of focus dramatically.

I'm sure I want be going back to this brand. As I wrote in another post, I'll continue to use this lens for closeups (product/art) and landscape (via LV focus) photography, and occasionally as a walk around lens - but I'm almost certain that third option will lead to often disappointment (due to average photos produced by inaccurate focus)... The worst use of hardly earned 800EUR I could have ever made.

F-ing lens! Finally I had some time and it was a nice weather, so I went out for a walk and took the camera with me. Big mistake! At 35mm pics were way out of focus. Nikons AF tune helped a bit, but I was to nervous to continue, so I went back home. New test showed that I need to change values in 3rd and 4th zone from +4 and -6 to +1 and 0 respectively. There's really no logic to this behavior and obviously Sigma's dock is worth nothing in this case. The lens is only good as paperweight...
