On a related note, here (gzip'd and attached) is the EXIF summary data from our Italy photos. I try to review data like this after each major trip, because it tells me many things about the suitability of the photo gear.

Eg. which lens I use the most, which focal lengths are used, etc.. If, for example, I notice that I'm constantly using the 17-85mm lens at the full 85mm setting, then I know that I really ought to have a longer lens in the bag.

It was data like this that got me to purchase the 10-22mm lens --> I noticed that whenever we traveled with the 16-35L or 17-85, there were tons of photos taken at 16mm or 17mm with those lenses. TONS of them. This told me that I really needed/wanted a wider lens.. thus the 10-22mm.

Cheers
