Honestly, I knew me from not really good as I bought this for my Tele D40. One of the main reasons for buying were the price. The situation has changed and I can say in retrospect, it was a real stroke of luck. Already in my first test images fell to with a sharpness and clarity that I was not used by the 18-55 ED II Kitlinse so. Meanwhile both my knowledge and my objective Park have increased. I own u. A, and the 85 / 3.5 Micro, a very good lens, and compared to the 55-200, I must say, I was at medium focal lengths often barely able to see the pictures of which the zoom Micro - to distinguish fixed focal length. The results are really convincing and CAs are also no problem. Who knows the 85er Micro, will know what I mean. Also due to sharpness aspects I see no reason that the preferable 70-300 55-200, as it is often mentioned in forums. Who needs more focus, ok, that's an argument. All in all, I am very satisfied.
