anyways...I got media passes for the tiesto event in LA. I've never shot in a club before...so there's going to be alot of lights & lasers going off. Plus the club has a high ceiling. What lens should i get? I'm thinking of renting a fisheye 15mm f2.8 but with the rebel's 1.6 crop...i don't think i'll be maximizing it so i'll prolly rent another canon body as well. I'll be getting a 580ex for sure, maybe a 24-70L f2.8 & a 70-200 f2.8 as well. I need all the help you guys can give me so I'll be prepared.
