Got myself the Sigma 10-20mm wide angle lens the other day. I've been wanting a wide angle mainly for outside shots and stuff. I love this lens already, and I haven't even taken a step outside yet! (Mainly because it's terribly cold at the moment) I know this lens can be used for all kinds of nature shots, but I am wondering, can you make it work for other things too? Like people, for example? And if you've used this lens, post your pictures or something I've seen a lot of good reviews on this lens!
