I almost always have a bag on me, lol. I used to carry around one of those little compact cameras all of the time years ago, and often carry my DLSR these days. Something smaller will be handy, I think. Racquetball size sounds good. Only time B 'plays' with my camera stuff is if I switch a lens and ask him to hold one while I fiddle with the other. Lucky for me he is tolerant and loving and will hold it with a bemused look on his face. Which 75mm? Or is it just the length on this format that people like?
