Hello all, I have been lurking here for while now gathering all the knowledge I can about photography. I own a Canon 40D that I have used over the past 7 months. I feel that the kit lens that it came with is really holding me back. So I am looking for a new lens. What my general interest are when it comes to photography is outdoors, wildlife, indoor soccer and aircraft. I am thinking about buying the Canon EF 70-200mm f/2.8L with IS lens. What would be some of the forum members suggestions when it comes to this lens. Also, I have read that the lens is heavy, so what would be a good tri-pod at a decent price to support my lens and camera. Thanks for looking.
