HOYA Pro1 Digital Close-Up Filter No. 3 The Close-Up No. 3 lenses turn a normal lens into a macro by reducing the lens, minimum focusing distance. Depth-of-field is shallow so use as small an aperture as possible. Close-Up No. 3 offers much more creativity! Digital Multi-Coated
Digital multi-coated filters greatly reduce the appearance of lens flare and ghosting caused by reflections. Black Almite Frame
Filters feature a black matte aluminum satin finish almite frame which reduces reflections. Black Rimmed Glass
These filters are equipped with black rimmed glass to reduce the chance of light reflecting off the edge.
