So I've just about saved up enough to buy a 15-85 lens. From what I've read it's one of the best lenses you can get if, like me, you're on a budget and can really only afford one.
As usually happens in these cases, however, now that I'm getting close to purchasing it, I'm wondering if there are other options I should be looking at. I have a T2i and sold the 28-135 lens I had because I didn't care for the IQ. Are there any other lenses, comparable to the 15-85 (either Canon or other makes) that offer similar range and similar performance for a similar price, or am I making the right choice in getting it?
