Since there is not much to think about and I agree with no questions asked those who awarded 5 stars here. Processing, running smoothness and operation 1A. Optical quality excellent, if you avoid the between 550 and 600 mm. So I can live fantastically, because in the range up to 550 mm it is knackscharf. Even freehand achieved outstanding results in the small zoo, the stabilization works well. Stored on the GH2 to Custom 1, the matching conditions: 800 ASA, the smallest possible Auto Focus Focus range. And remember: dim the images at 0.3 to 0.6 because of the strong message the ambient light is not sufficiently considered. I'm almost always in the middle of the object, so that the automatic exposure is my object sometimes a little too bright. I know of no better, comparable favorable objective for the GH2 known!
