Definitely more than gear pron, including people, nature, traveling, etc. While the web would be the more likely place for gear shots, we do make prints for albums and framing on occasion. I was focused on the lens because even though I wasn't focused on full frame envy I have not been satisfied with the relatively lacking packaged lens (28-135, f/3.5-5.6) that came with the 40D (which I bought as CompUSA closed its doors). I enjoyed checking out the lenses and think that 40D with better lens options would be adequate. The new question posed today is what is lost by sticking with the 40D's 1.6x system?
Thanks for the offer of the light tent, which is probably a solution for lots of the gear photo issues. Taking pics on the racks won't allow that, however, unless you got one big-ass tent.
