It's my favorite lens, too. Great results on both 5DIII and 7D. If I had to look for quibbles, it would be that the lens hood on mine isn't secure enough in busy environments unless I use a bit of gaffers tape to keep it from rotating.
Same with my hood. I use two very small pieces of plastic pushed into the slot where the locking-"bumps" are from inside the hood to push them further out and lock harder, it works, but I can't tell you how many times I have taken a quick shot of something and have top and bottom corner all black from the slightly twisted hood, REALLY annoying.
I love my 24 and agree with the review completely. 1.4 at 24 is unique when used with a close'ish subject. I am on my third copy, the first two had the same focusing error, tested it in one shot with a LensCal target on a tripod, defocused between shots, and 18 out of 20 were completely off and the last two where far from useable, seems just random when it tried to focus. MY current copy works like it should, but the precision of AF is not even kind of close to the 35.
