And I also want to note its unsuitability as an alternative to portraiture. Of course, the lens was not intended for shooting people, this is so, as a warning to overly optimistic comrades. It makes sense to put this lens on a full frame camera to fully enjoy its "wide view of the world" and a wonderful, rich picture. Its pros: A very reliable thing indeed. Devilishly smartly induced. Different cons: It reveals its potential on 5D, in combination with 7D it gives a rather dull picture. I personally remained unsatisfied during the entire period of operation of this bundle.
