The 39mm MRC BASIC 007 Clear Filter from B+W protects the front of your lens against the elements such as sand, dust, fingerprints, and splashing water. The filter is fully color-neutral and highly transparent. Featuring B+W's standard MRC coating (as opposed to MRC nano), it also 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 coating, water droplets take on a rounded shape. They bead away from the surface, and a dirt- and water-repellent effect occurs.
