Protect your camera's lens while shielding it from ultraviolet rays that can create haze in some photos. A filter on the front of your lens can keep a minor ding from becoming a major problem.
These filters are made to exacting standards. The glass is specially blended for optimal optical results, and the careful multi-coating process minimizes any reflections from the glass that might cause flaring or ghosting. A rigid, protective aluminum frame keeps the filter firmly in place, and the low profile makes it compatible with many super- and ultra-wide angle lenses that otherwise might not be able to accommodate a filter.
