And I don't know what lens to get for my first.. I was thinking about the EF 50 f/1.4 or the 17-85mm IS and I'm thinking about the EF 24-70mm f/2.8L USM I know there's a huge difference in price but I cant figure out which one would benefit me the best. I'd be taking alot of pictures at car shows, both indoor and out. Not just pictures of stationary cars but moving models and moving cars. Also 1 on 1 model shoots, and I will probably be getting some lights soon and setup a small studio.
