I'm probably going to buy another one/two lenses while I'm out in Seattle in June/July.

I want a wider lens, at the moment I'm looking at the EF 17-40 f/4.0 "L" or the EF 15mm f/2.8 fisheye (with software to flatten the fisheye to just be a wide angle view).

My wife wants a longer lens, at the moment I'm thinking about the EF 75-300 f/4-5.6 IS. I know this lens isn't the best quality in the world, but I don't have the budget (or the desire to lug around) a better long telephoto...
