How many are having back focus problems with their 7D? DPreview seems loaded with victims.

Just got a Sigma 18-50 3.5-5.6 lens today, backfocus is awful. I've read that a lot have had this problem, some have not. May return the lens for a replacement, as I have seen others do this, though with mixed results. I then put my Quantaray 28-80 on, no BF at all that I can detect. I am no expert, but the Sigma seems to be VERY bad with BF.

To be honest, though, I am reading elsewhere that Wide Angle BF is a problem on the 7D with other lenses. I am going to take the camera to a shop locally and test a couple of other wide angle lenses to see. This will help me determine if the problem is with the camera, or just the Sigma lens.
