I am wanting to get into photography and now I am ready to get my equipment. I've done some research and I don't think I'm ready for a high-end Canon or Nikon, plus I'm on a lower budget, so I'm thinking of a Pentax or Olympus. I am mostly going to do a lot of snowboarding, skiing, skateboarding, ect. Extreme sports like that. so can anyone recommend some good cameras and what I'll need?
