I need a fast lens for shooting snowboarding: rails, jumps, ect. I think I want a zoom since I want it to be versatile. I am shooting with a 50D. I have a 50mm 1.8, but that requires me to be too far away from the action. I would like something small that I can carry with me while I ride. My price range depends on what else I can use the lens for. I'm not going to drop a grand on a lens just for snowboarding. I saw other people saying they were using a 70-200 for rail jams. Isn't that overkill? Any recommendations?
What kind of flash should I be looking for? I have never used flashes and know nothing about them.
