Wow. Fuck yes dude, thanks a lot for this! At first I was just debating on the t2i and the 7D because that's what some of my friends use and those are the ones I could've got more info from, but since you've mentioned the 60d, then I'll look into it too. And people I know that are into photography told me kinda the same thing you just said about lenses lol They told me that a pretty big percentage of the quality in a picture is mainly due to the lens, and the rest is from the quality of the camera itself and stuff. I don't know if this is true, but whatever haha.
The main reason I was looking into t2i was because as I was watching skate videos on youtube, and some dude had an amazing quality and asked him what camera he uses, and he said he was using the t2i with some lens I can't remember. I was considering the 7D because of it's fps and other features that were better than the t2i. I'll have to look more into the 60d though, because I want a camera that can shoot decent photos and also film HD.
Anyways, thanks a ton for the advice and everything dude, I really appreciate it. I'll definitely consider the 60d and that 50mm prime lens w/ 1.8 fstop haha
