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.

Lens hoods are primarily designed to prevent unwanted stray light from entering by extending and shading the end of the lens, ensuring no problems with vignetting or motor functions. Additionally, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. Lens hoods match the specific focal length of the lens it was designed for.

A lens hood is one of the most important accessories for each lens you own. A lens hood provides multiple functions: it shades the lens from stray light, improving your contrast and image quality; in inclement weather, it can assist in keeping moisture or wind-blown debris off the lens; and it protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles.
