Ricoh GR IV Monochrome Digital Camera

Ricoh GR IV Monochrome

The Ultimate In Black-And-White Photography

The Ricoh GR IV Monochrome is based on the RICOH GR IV, which fully and legitimately evolves the GR series' fundamental concept - the essential values of a camera, including high image quality, quick response and portability - while newly incorporating a monochrome-dedicated image sensor

Monochrome-dedicated design

With the pursuit of the ultimate monochrome expression, the camera is newly equipped with a anti-aliasing (AA) filterless monochrome-dedicated CMOS image sensor of APS-C- equivalent size, capable of producing high-definition images with approximately 25.74 million effective pixels. Unlike monochrome images produced using a general color image sensor—where each pixel receives light through one of red (R), green (G), or blue (B) color filters, the information is interpolated to generate a color image, and the result is then converted to monochrome—each pixel of the monochrome- dedicated sensor captures the subject’s brightness information. Because it directly takes in the light information entering through the lens without interpolation processing, it enables sharp monochrome rendering with rich tonal gradation, and also makes it possible to create works that emphasize grain effects by taking advantage of high- sensitivity performance. 

Built-in red filter in the lens unit 

A red filter that can be turned ON/OFF with a single operation is built into the lens unit. By allowing only red wavelengths of light to pass through, it enables dramatic rendering—for example, by darkening the tones of a blue sky to enhance contrast with white clouds, or by rendering red subjects brighter to make them stand out more clearly. 

Electronic shutter enabling high-speed shooting up to 1/16000s

In addition to the conventional mechanical shutter, the camera is equipped with an electronic shutter that enables shooting at higher shutter speeds. The shutter speed can be increased up to 1/16000s, which is effective for creative work that takes advantage of the monochrome sensor’s high- sensitivity characteristics in bright conditions, and for situations where it is desirable to shoot with the aperture open even in very bright environments.
