Canon 30.5mm Filter Set with Neutral Density & Lens Protector.

The neutral density (ND 8) filter acts as sunglasses for your lens, cutting the blazing high noon sun down to a cool 25% of its full strength---so your images won't appear washed out by glare. The clear MC protector shields your camcorder's lens from dust, dirt, and accidental damage.
