With the exceptional image quality, quick response, and outstanding portability that the GR series is known for, the GR IV Monochrome incorporates a monochrome-dedicated image sensor. By eliminating the color filter used to acquire color information, as well as the interpolation process required to generate color images, the camera can fully draw out the capabilities of the high-performance GR lens, delivering refined rendering and rich tonal gradation.

A built-in red filter enables more distinctive monochrome photography, while two newly developed Image Control options dedicated to monochrome imaging provide deep and diverse monochrome expressions.
