I can't express how valuable a UV lens can be for your camera. It's an inexpensive way to protect your lens from scratches, or any other variety of projectiles or damage causing agents. Even cleaning the camera lens by wiping it can scratch the lens if it's not done correctly. Don't take any chances with expensive repairs to your lens. Some ads claim it fixes haze caused by UV light...I can't confirm this. Hazy days still look hazy from my experience, but that's not why I use a UV filter. If the UV filter gets damaged, I can simply replace it and not worry about the camera lens.
