I did the same thing, only I gave up after the first one. Didn't want to deal with the hassle of getting a second bad copy. I'm VERY happy with my Canon 50. Sharp at 1.4, and lightweight....fast focusing. It may not feel as sturdy as the Sigma, but in the end, it's the IQ we really care about anyway.
Couldn't agree more. Can't wait to get it so I can get shooting again. I'm kind of burnt out on using the 70-200 F/4L as a walk around lens.
