B+W 1101525 67mm Master Clear MRC Nano Filter

The B+W 1101525 Master Clear MRC Nano 007M is a 67mm protection filter built for photographers who want front-element insurance without optical compromise. The glass is fully clear—no UV tint, no warming effect, no light loss—so it can stay on the lens permanently without influencing exposure or color balance. What sets it apart from basic clear filters is the MRC Nano coating, a multi-layer treatment that causes water to bead and roll off the surface, carrying dust and debris with it. Oil-based smudges wipe away with less effort, which matters during fast-paced shoots where stopping to clean glass costs frames.

The filter's thin profile mount is engineered for wide-angle use down to 17mm on full frame bodies, keeping the ring out of the image circle where thicker mounts would intrude. A knurled texture around the edge provides grip that generic smooth-ring filters lack, a practical detail when threading filters in cold weather or with gloves. B+W has also added a QR code verification system to the packaging, addressing the counterfeit filter problem that has grown alongside online marketplace sales. For photographers who treat a clear filter as standard lens protection, the Master Clear MRC Nano represents the upper tier of the category—minimal optical impact paired with a coating that genuinely reduces maintenance.
