Marumi Digital Coating
Digital Cameras CCD and CMOS sensors convert light into electronic signals. For this reason, on certain occassions lenses produce inner reflection, flare, ghosting and other phenonmenon which result in poor quality images.
Marumi Digital High Grade Filters are specially designed not to interfere with camera CCD´s and CMOS sensors. They are designed for use with Digital SLR cameras. Each filter has a special ultra-low reflection coating coupled with a black outer filter edge, which significantly reduces glare, ghost imaging and over exposure.
The Polarising filter maximises the lens performance. It assists the photographer in controlling reflections and balancing contrast in pictures. It is suitable for use with wide angle lenses.
For added convenience the lens cap may still be used with the filter on the lens.
