Product Description:
Film, as well as video, often exhibits a greater sensitivity to what is to us invisible, ultraviolet light. This is most often outdoors, especially at high altitudes, where the UV-absorbing atmosphere is thinner; and over long distances, such as marine scenes. It can show up as a bluish color cast with color film, or it can cause a low-contrast haze that diminishes details, especially when viewing far-away objects, in either color or black-and-white. Ultraviolet filters absorb UV light generally without affecting light in the visible region. It is important to distinguish between UV-generated haze and that of air-borne particles, such as smog. The latter is made up of opaque matter that absorbs visible light as well as UV, and will not be appreciably removed by a UV filter.The UV Protector shields lens from dust, moisture, scratches, and breakage.

I love your neutral greyness
and the way you reduce the light rays
that strike my sensor by one stop.
You screw-in and screw out, 52 mm
no doubt. You are something I cannot
do without. I Adore--rama you.
