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.

Protection
It's like not having anything on at all. But isn't that the point. It is there to take the abuse if an accidental bump to the lens happens. I think it is a wonderful investment to protect a $1700 lens.

UV filter a problem
Overall I like these filters. I use many Tiffen filters without any issues, but there is one problem with the UV filter. I use these on a Sigma 10-20 mm wide angle zoom lens. Because of the wide angle, the glass protrudes outward from the lens in a bubble. The UV filter, when screwed on actually touches the glass of the lens. The other two filters are recessed enough that they don't touch.
Just a warning for folks with wide angle zooms, otherwise a great product. The CP filter is excellent! It really punches up the color and reduces glare on water and glass.
