B+W 1102696 49mm Dark Red MRC Filter

The B+W 49mm Basic Black & White Dark Red MRC 091M filter is a specialized tool for monochrome photographers who want to push contrast and tonal separation beyond what lighter-colored filters can achieve. By blocking most of the blue and green spectrum, the dark red glass renders blue skies as deep, near-black tones while allowing red and warm-toned subjects to appear brighter. This creates dramatic landscape images, strong cloud definition, and the distinctive simulated-moonlight look when shooting daylight scenes on black-and-white film or with a monochrome digital conversion.

Build quality reflects B+W's professional-grade standards: the filter uses optical glass for edge-to-edge sharpness and is housed in a precision-machined brass ring with a knurled black finish that threads securely without binding. The Multi Resistant Coating serves double duty — it reduces internal reflections that cause flare and ghosting, and it adds a hydrophobic layer that repels water and fingerprints for easier field maintenance. Rated for use on full-frame lenses with focal lengths of 24mm and above, this 49mm filter fits a wide range of prime and compact zoom lenses without introducing corner vignetting.
