Marumi DHG Soft Fantasy Filter 52mm [DHG52SFAN] Marumi DHG Filters eliminate the flare and ghosting prevalent when the CCD or CMOS chips in digital cameras convert light into electrical signals. Marumi's Proprietary ultra-low reflection coating increases light transmission. Lens' outer rim is blackened to minimize internal reflection. Satin smooth, ultra thin, matte-black metal filter frame further minimizes refection.
