I thought I found the problem. I peeled back the rubber on the zoom ring and one of the screws was almost completely out. Screwed it back in and I got 17mm more often but not always. Not going to worry about it at this time.

Just to add my experience, when I had the 17-40: I used it a while back on a 20D and it always reported 17mm. When I upgraded to a 5D2, all of a sudden, it only reported 19mm! It never received any harsh treatment at all. Unfortunately, I did not get to re-try it on the 20D as I had then sold it. The guy who bought it was also using a 5D2 and it reported only 19mm as well. I offered to pay to have it sent to Canon for a look, but he was fine with it the way it was. Interesting to see several other users also have theirs report at 19mm.

That's interesting. Wish I knew that when I had the lens
