No I owned the 35l a few years ago. I also rented a copy. Results at f1.4 -- f2 were soft, unusable to me unless I had no choice. I don't think anyone who has used both lenses will dispute that the sigma is better at least until f2.
Agreed. My copy of 35L f 1.4 is really a f 2 lens, but I'm still holding onto it since I need to test my copy of the Sigma 35 more.

my 70-200 os, 85 1.4, and 35 1.4 were all perfect out of the box, performed exceptionally, and came at a great price. I wouldn't trade any of them for the canon version.
Sounds like you have a good one. I really don't suggest people go looking for problems. This has been my approach all along. They kept subtly presenting themselves after I had decided to just get on with loving the lens. Then I would find myself back testing and finding just enough to make me think mine was a little wonky. So, I def. do not consider myself a "half-empty" owner, just one that maybe needs a different copy of this sweet piece of glass. I think darn near everyone with the exception of a few are finding it to be just fine, albeit with bit of MA, which should be considered normal.
