Meco 52mm CPL Filter

52mm MC UV (Multi-coated) Filter for Nikon, Canon, DSLR. Digital cameras require special filters. MC filters eliminate the flare and ghosting prevalent when CCD or CMOS chips in digital cameras convert light into electrical signals. Films and CCDs behind camera lenses are sensitive to ultra-violet rays (UV rays). UV rays are invisible to our eyes but when they are recorded on a CCD, the image may appear blue and the color cast may thus be distorted. Extreme auctions in outdoor photography often occur in open shade under a clear, blue sky and water front while haze is mostly caused by dust particles in the air. When daylight shines through the sky, the particles reflect shorter wavelengths of light over longer periods. This UV filter helps to effectively eliminate the lack of sharpness, Absorbs UV which causes blue cast, as well as reduces distant haze caused by UV radiation. It also protects your camera lens from dust and scratches.
