B + W Filter Company 37mm Master 010M UV Haze MRC Nano camera filter

37mm UV protection for analog and digital lenses

The B+W Master 010M filter threads onto 37mm front threads to block ultraviolet haze that causes blur and a blue cast in maritime or high-altitude light. Its color-neutral glass preserves the original tone and contrast of every exposure, making it suitable for both film and digital sensors. The slim mount avoids vignetting on wide-angle lenses while staying in place as a permanent guard.

Fits 37mm threads and frees the front element

Once screwed on, the filter shields the front glass from sand, dust, fingerprints and water splashes without requiring a separate lens cap during active shooting. The coating repels moisture and grime so cleaning is quicker, keeping workflow uninterrupted in unpredictable conditions. No adapter rings or step-up rings are included, so the lens must already present a 37mm thread.

MRC nano-coating cuts reflections

Multi-resistant coating layers reduce flare and ghosting from stray light while hardening the surface against micro-scratches during wiping. The hydrophobic top layer causes water to bead and roll off, reducing streak marks after rain or sea spray. No cleaning fluid, cloth or pouch is bundled, so users supply their own maintenance kit.
