Actually, I have at this price also expect nothing less than a top product. More you need more than the Canon lens does not write well. While it is in proportion other (Tamron, Sigma) Although much more expensive, but worth the money. The only small minus is that the speed of the autofocus (for a USM-device) is not really that's how I expect it at this price! Use it on an EOS 700D, if that is important for anyone.
