Review on Canon EF-S 17-55mm f/2.8 IS USM Lens - Compatible with Canon DSLR Cameras (Lens Only) by Guo Tai Lim ᠌

I use tamron 17-50 as a marching tamron 17-50 for 60D, I have always been pleased with it. The other day I managed to hold it in my hands and take a couple of photos on this canon - the difference in favor of the latter is palpable. - He's really heavy. - In the absence of light under the same conditions, the tamron cannot "catch" those details that the canon calmly and without straining catches with the help of a stub. - The way he focuses even next to the USM tamron is just a song. I made samples on the same specifications: 3.5 iso 100, 50mm. When comparing, there was a feeling that the tamron, in principle, does not have a zone of sharpness, perhaps it just needs to be adjusted somehow. Before canon, I thought that the 60D out of 18 megapixels had a good 6-9 added by marketers :) After that, the impression remains that canon works out all these cropped 18mpx honestly. Here is a comparison on a colleague: http://fotki. . Ru/users/a-n-dolgov/view/577472/ (canon, of course, on the right) Both lenses are good, but they differ in price and weight by 2.5 times. It’s just that this one is for those croppers for whom the picture is more important than the weight behind their backs and the numbers in the check for the glass, but at the same time, FF and elks are already (or still) that match.
