Mamiya/Leaf Mamiya IR Photo Filter YD401 for the ZD Digital Back

CCD sensors are very sensitive to infrared light. The IR Cut filter on all digital cameras and backs reduces Infrared light transmission so that the color of the image will appear accurate and natural. This filter, however, makes Infrared photography impossible.

There has been a significant amount of interest in Infrared Digital Photography, especially with the increased scarcity of infrared film. In response to the large number of requests from infrared photographers, Mamiya has developed an IR Photo Filter for use on the Mamiya ZD Digital Back.

The IR Photo Filter YD401 (which replaces the standard IR Cut Filter) is a clear filter that allows the transmission of infrared light as well as visible light rays. Unlike specialized IR cameras or modified systems, the Mamiya ZD Digital Back can be transformed from standard digital to IR digital, simply by changing the user-replaceable filters.

Photographers will need to add an Infrared filter (89B or 87) on the front of the lens to produce Infrared images with dramatic dark skies, glowing greens and "magical" skin tones.
