Summary: I bought this lens a few weeks ago and it consistently produces out of focus images at f/2.8 through f/4.0 Amazon was great to work with, and they sent a replacement which turned out to be defective as well. I've shot several hundred images on each, under various lighting conditions, using my 5D Mark II body. The two exaples I evaluated are very poor performers at f/4.0 and wider. One went back to Amazon as defective, another went to Canon for a warranty claim.
