Canon 16-35 for 7d

I bought it as an upgrade for the 18-55 kit lens on my 500D and was completely underwhelmed by its performance. Into the drybox it went then  a few months later I bought the 5DM2 and almost as an after thought I put it on, and wow, what a difference. I love it, but I'll tell you a wide lens that I've only recently redicovered on the crop and that's the Samyang 14f2.8, I find its a very good walk around lens. I was going to give mine away but its found a new home on the 500D.
