I've ordered myself the Canon EOS 450D Digital SLR Camera Twin IS Lens Kit with : 18-55mm IS + 55-250mm IS Lens... I'll be using this camera for the car Sprints at the end of June.. My question is do you advise me to get any filters for either protection or UV filters for the event? I'll be right next to the racetrack on the front straight to get some great shots. Are filters worth it? I see people saying that yes they are great for protection, and others saying they wouldn't use them becuase putting a cheap peice of glass on the ends of your lens doesn't help image quality. Can OTAP recommend any filters for the setup i'll be using?
