I have this goal that I use for 3 years now. Initially I had the 450D and 550D now on. It's just happiness, USM ultra silent and high-speed, image quality at top right from F4. The only fault we can sometimes read on specialized sites is that the extreme edges are not great on a full frame sensor (24x36mm) but "fault" does not exist on a "small" for APS-C sensor the sensor is smaller so I would venture to say almost that this objective no longer has any defect in a case such as XXXD, XXD and 7D. I deleted a star for the price which is still Therefore, especially in this period, and then for the ranks that could annoy some. In my case, it's perfect for 27-64mm reporting, excellent in every way. A purchase you will not regret, do not forget to go on to another site that Amazon, because for the same price you will find the lens with a 2 year warranty! Amazon only offers a year! a point to note is that size I think :)
