Due to the numerous Emfehlungen of other Amazon customers I bought the lens and was not disappointed. I'm only an amateur photographer, but I succeed most shots. Especially in the 300mm range thinks you look, oh jeh, photos blurred determined but it is not so. The USM-Fofus works very accurate and reliable, and the pictures are sharp. It is very well made and can be affairs well. And all this at a good price. And so my conclusion: Buy I myself own a Canon EOS 450 D
