The 49mm UV-Haze #010 MRC MASTER Filter from B+W blocks UV light, which can cause blurring and a blueish cast. An invisible component of daylight, UV light is more intense in pure sea air and high mountain regions. This filter is color-neutral and can be kept on your lens even when you don't need it, simply to protect the front of the lens. The filter element is made of glass and is highly transparent.

Featuring B+W's MRC nano coating, the filter has an extremely low reflection. The optical information remains unaffected when it reaches the image sensor. The hydrophobic coating reduces the adhesion tendency of dirt particles and water droplets. With MRC nano coating, a water droplet remains practically spherical. It rolls over the surface, and a first-rate dirt- and water-repellent effect occurs.

Q: 10. What is the difference between the MRC & MRC Nano coatings?

A: "Multi Resistant Coating" (MRC) and "Nano" coating are now combined on B+W filters: the coating resists dust and moisture, and offers significant resistance to mechanical scratches on the surface of the lens. Cleaning filters with the hard, water-repellant MRC Nano system of coatings is considerably easier than cleaning filters without this coating.
