This is a lens filter for your camera. My brother and Mom have these for their lenses and it's a must have. See, if you scratch your lens, that is an expensive fix. This little guy screws onto the end of your lens and protects it from damage. It's ten buck, and it can save you hundreds. I've been wanting to get these puppies for months now but haven't been out to get them. I have one for each of my lenses now, thanks to Sean. I finally feel safe. Plus, it also is supposed to produce sharper, more vivid images, but honestly, I don't really care about that. My baby is now protected, and if this lens filter gets scratched, you just buy a new one for 10 bucks. If you don't have one, get one. You will be happy.
