This 40.5mm #495/022 Yellow MRC Basic Filter from B+W can be used to increase image contrast when using black-and-white film. When using this filter, blue and green subjects are rendered in darker shades of gray while yellows, reds, and other warm tones are lightened, producing a more natural-looking outdoor look. This filter can also minimize the haze caused by the bluish cast of daylight.
B+W MRC Basic filters are made with the exclusive Multi-Resistant Coating (MRC) nano premium coating technology. This high-quality broadband coating is applied on both sides and enhances the optical imaging properties, allowing uniform and increased transmittance across the entire light spectrum to be achieved, with minimal physically induced remaining reflection. The nano all-around protection on the filter glass also ensures increased scratch resistance and extremely fast, easy cleaning, providing a long filter life. The slim filter ring design is compatible with wide-angle lenses with an equivalent width of a 17mm full-frame lens. The top knurling is redesigned for enhanced gripping.
