| p.1 #7 · Canon 20-35 f2.8L or 17-40 f4L? |
In addition to FM reviews, you might find this review helpful as well.
I have the "plastic" version of the 20-35 and it served me well back in the 90s but it's IQ is nothing like an L; my budget couldn't afford L's back then. I shoot crop bodies like you do, a 40D and 50D, and decided on the 10-22 given it's great reviews...those reviews proved correct, it is super sharp, with little distortion.
Recently my budget found a few extra bucks and a super copy of the 17-40 became part of my kit and I really love this lens. I've only one EF-S lens and will not buy another as I'll be adding a full frame body soon. But I've not required fast zooms so far, I've left that to fast primes at f1.8 and faster.
If I need a stop faster tho, the 17-55 is the lens to think on, it's wider than the 20-35, has a larger focal length range, gets you IS, and a constant f2.8 apreture. I'm not sure you can go wrong with it, just like the 10-22 it will have a good-to-great resale value if you move to only FF.
Good luck with your selection.
