So I have to say that I can not connect the positive as me. clear, the thing is not bad. but for what you are buying for a tele? among other things, for Animal and Nature Photography and then accordingly not having to stand in front of the motif 5 meters. have now some try with ner 7D made, motives were not soooooooo far away. eg a dove in the hedge opposite, less than 20 meters. The results are rather disappointing. the settings on the 7D were actually optimal. but the image quality rather sobering. Sure, you can not compare it with NEM Canon L-series, also do not expect that do not cost nothing much more. but more quality I would have expected. Therefore, I am surprised frankly about the many top reviews and a little place at the same time ask a question. what and how to photograph people so? wildlife photography how anxious to make it with a telephoto / should it can not be, unless we are talking again of the 5 meters distance to the subject.
