I got the lockup once when changing lenses. I had to remove the battery to "reboot" the camera. It only happened the once, during testing of the camera the day I got it (over 2 weeks ago), but I never again got it anywhere during my trip in Italy. I got the lockup after using an old Sigma lens, that only works wide open. (I get an error if I try to stop the lens down.) In Italy I used only Canon lenses. I wonder if that makes a difference but I believe others have gotten the same problem with Canon lenses. There is supposed to be a firmware update coming very soon though.
Tuscany is very nice. Lots of good food and wine.
I will try to post a full-rez picture, but the problem is the pix are something like 3-5 MB, and I'm outa space ot pbase.com and my own space.
GTaudiophile, yes, the 17-85 does exhibit chromatic aberration, but quite frankly I haven't noticed it much in real-life usage. However, if I really look for it... it seems worst at 17 wide open, but really is only visible at very high contrast areas (white on black etc.) and when you're at 50 or 100% crops. In standard pix it's pretty minor. Actually I think some people out there have more CA than I do, maybe due to variation in the lens builds. I'd prefer a lens with no CA, higher contrast, faster speed, and better sharpness, but I don't want a 4 lb walkaround lens either. Plus, I tend not to take the classic sun-behind-the-leaves pics. Those pics usually suck anyways, regardless if there is CA or not.
