Hi Chris, I have the 100 f2.8 USM macro and use it on my 10D. A short time ago I was sufficiently worried about barrel distortion with this lens that I did a specific test on subjects effectively at infinity. (I assume that being a macro, it will be fine in the close-up range, and I'm not in to snapping postage stamps.) Well, the test didn't show any distortion, so I suppose the manor house which originally raised my worries must have a distorted roof line! However, it's a bit strange that I can see the effect clearly on screen, but not in reality when I re-visited the house for a check. I don't have the 50 f1.4.
