B+W F-Pro MRC

This UV filter blocks the invisible UV component of light from the sky, which can cause blurriness and to which many color films react with a bluish tint. These filters should be referred to as UV-blocking filters, as there are also filters for technical applications that allow UV radiation to pass through while blocking all other wavelengths. Nevertheless, the term "UV filter" has become established among photographers. UV filters are ideal for photography at high altitudes (in the mountains), by the sea, and in regions with very clean air. The images gain brilliance, and distracting blue tones are avoided. Since the glass is colorless, color reproduction is not altered, aside from eliminating the unwanted blue tint, and no increase in exposure is required. This makes a UV filter very suitable as protection for the front element of the lens against dust, flying sand, sea salt spray, and similar elements, and it can be left on the lens at all times. It is recommended for both analog color and black-and-white photography as well as for digital photography.

MRC (Multi-Resistant Coating) from B+W is not only an exceptionally effective multi-layer coating but also harder than glass, protecting filters from scratches (for example, during cleaning), and it is also water- and dirt-repellent, making filter maintenance easier.
