B+W UV-Protection Filter

The UV filter is one of the most important filters there are, and it should be available for every lens. It has two important purposes.

The filter blocks the invisible UV rays which can cause a loss of sharpness. The use of the filter is particularly recommended for work in the mountains, at the ocean, and in areas with very clear air. The contrasts are heightened, and distorting fog is avoided. The colors come out more clearly, and telephoto pictures have more clarity and sharpness. The filter glass is colorless, and hence no increase in the exposure time is required.

This type of filter is also eminently suitable as protection for the front lens, and because of its color-neutral properties it can remain on the camera lens permanently. A scratched front element of a lens cannot be repaired; a replacement of a damaged front lens element is not often worth while. A good filter is in any case more advantageous than the purchase of a new lens.

The UV filter is utilized in connection with digital cameras, as well as in analog photography in color and black and white. What is especially important is the high optical and mechanical quality of the kind of filter that B+W guarantees, since filters with lens elements with rippled glass or deficient coating reduce the performance of a lens.
