Choosing a wide angle lens for my 60D

I love the 60D. I originally though about a 3/4 but am pleased with the 60D. I am somewhat disappointed the EF-S lens do not take extenders but the 60D will take the standard EF lens so I am now using the EF lens when I get a new one. I do not do a lot of video, but it is quite nice to have when needed. I also do not use the articulating screen much but again, when needed it is nice to have.

One suggestion. If you get the 60D, do install Magic Lantern firmware. It is awesome!
