B+W 1102638 49mm Basic Yellow MRC Black & White Filter

The B+W 1102638 49mm Basic Yellow MRC Filter is a purpose-built optical accessory for black and white photographers who want to take control of gray-tone rendering in their images. By absorbing a portion of blue light, this yellow filter darkens skies to make clouds stand out more dramatically, brightens skin tones for more flattering portraits, and differentiates between various shades of green in foliage and plant life. The result is a more expressive and visually separated tonal range than you would achieve shooting black and white without filtration.

Built with optical glass in a brass mount, the filter is designed to maintain image quality without introducing softness or distortion. The MRC (Multi Resistant Coating) is a key feature, reducing lens flare and ghosting from stray light while providing a surface that resists fingerprints, water spots, and dust — making field cleaning quick and reliable. The black knurled edge of the mount offers a tactile grip that makes threading the filter on and off straightforward, even in cold conditions. B+W has also included a QR code for authenticity verification, giving buyers confidence they are using a genuine product. At 49mm, this filter fits a range of compact prime and kit lenses, and B+W rates it for use on full-frame formats down to 24mm focal length without vignetting. The eco-friendly packaging reflects a modern manufacturing approach without compromising the quality of the filter inside.
