B+W 1101520 52mm Master Clear MRC Nano Filter

The B+W 52mm Master Clear MRC Nano 007M filter is a high-quality lens protection filter built for photographers who want to safeguard their front element without any optical compromise. The filter glass is engineered to be fully transparent with no filter effect and no light loss, meaning it can stay on your lens at all times as a barrier against scratches, dust, and accidental contact. The MRC Nano (Multi-Resistant Coating Nano) treatment on the glass surfaces reduces reflections while creating a hydrophobic and oleophobic barrier that causes water to bead off and makes fingerprints and smudges easy to wipe clean.

The filter sits in B+W's Master series thin-profile black knurled mount, which serves two practical purposes: the knurling provides a confident grip for threading the filter on and off, and the slim profile keeps the ring out of the frame on wide-angle lenses down to 17mm on full-frame bodies. At 52mm, it fits a wide range of standard and kit lenses. B+W also includes a QR code with each filter for authenticity verification, and the packaging follows an eco-friendly design. For photographers who treat lens protection as a permanent part of their kit, this filter delivers clean optics and durability in a well-machined package.
