Made from Asahi optical glass and featuring Kenko multi-coating technology, the FL-W is quality you expect.
Kenko FL-W filters are for controlling the green and purple tones that fluorescent lighting can give when shooting on film. Digital sensors can also benefit by making color corrections optically thereby increasing bit depth and decreasing post processing time.
Mounted in a slim low-profile ring for maximum protection from unwanted vignetting on wide angle lenses. The filter mounting ring has a black anti-reflective mounting ring to avoid unwanted flare and reflection from the filter mounting ring.
