The first copy had a distinct front Focus ... the second copy makes slight noise at one-and out of the tube. Because of autofocus but precise sitting, I keep it. About the lens itself does not have much to say. Knackscharf into the corners, nice contrast and for my taste a nice bokeh. For professional video recordings, I did not need image stabilization and miss in therefore not (of course would have been nice for the price). The filter thread diameter of 82mm is at Crop cameras no problem because you can use a step-down adapter (eg 72mm), without which there are problems in the corners ..... A super lens that is suitable for many and in the Abbildungsqualiät exceeds some fixed focal length ....
