Infrared Contamination
The D2H series has a relatively weak infrared (IR) filter, causing certain dark-colored fabrics to take on a slight magenta color cast. Skin tones may also appear slightly ruddy. Use of a No. 486 digital UV/IR blocking filter can help resolve the problem with lenses that are at least 50 mm or longer. Lenses shorter than 50 mm are not recommended for use with a No. 486 filter due to a tendency for the corners of the image to take on a cyan color cast.
