Ricoh has announced the Pentax K-3 Mark III Monochrome: a variant of its 25.7MP APS-C DSLR with no color filter array.
The K-3 III monochrome gains all the usual benefits of removing the color filter
The K-3 III monochrome gains all the usual benefits of removing the color filter: sharper images by avoiding the need for demosaicing and one stop better tonal quality than the color version, at any given ISO, because no light is being lost to filters. The low-light benefit is further enhanced by an absence of chroma noise, which means all noise presents as luminance noise, which can be read as ‘grain’ or additional detail.
The Monochrome version has revised processing modes and parameters in place of the usual color modes, to allow options such as high- and low-key photography. As well as stills, the K-3 III Monochrome can shoot black-and-white video at up to 4K/30p.
