Minimum focus distance
comment:Just got this lens and I am very pleased with fast AF and IQ in general. It is heavy and minimum focus distance is too big, but other than that, it is great lens! Worth all the money and doesn't matter that it is old almost as I am. Sharpness is great on all f values and only difference that can be noticed are corners when shoting wide. With f 4-6.3 corners are soft, but with f 7 or higher, softness dissapear. Since center is OK always, I don't mind.
What is a little problem, and I don't know if it is general case or just a issue with my copy, is that on 28mm it suffers of back focus. I need to zoom in, focus, lock focus and zoom out, than shot. This way everything is perfect. But focusing when wide, always result with back focus. The same happens with my Sigma 17-70 f2.8-4 and happens both on DSLR and SLT.
