Ricoh GR IV Monochrome Digital Camera

The First GR Dedicated to Black-and-White

The “ultimate snap shooter” designed exclusively for monochrome photography, the Ricoh GR IV Monochrome is a specialized version of the popular compact fixed-lens camera. It features a uniquely modified sensor that records only black-and-white imagery, delivering enhanced clarity and tonal depth.

Beyond the black-and-white–only 25.7MP sensor, this Monochrome model includes a built-in selectable red contrast filter, replacing the ND filter found on the standard GR IV. The camera also introduces monochrome-specific Image Control options and an updated exterior design with a refined monochrome aesthetic.

Aside from these targeted updates, the GR IV Monochrome remains virtually identical to the standard GR IV, including the 28mm-equivalent lens, fast autofocus, refined Shake Reduction, and improved wireless control via the GR WORLD app.

Monochrome-Specific Imaging Technology

The 25.7MP APS-C CMOS sensor lacks both an anti-aliasing filter and a color filter array (CFA), allowing it to record imagery using pure luminance values. This results in improved sharpness, higher resolution, and a broader native sensitivity range of ISO 160–409600.

With no color interpolation at the sensor level, black-and-white images exhibit rich tonal gradation and more natural-looking grain, closely resembling traditional film characteristics.

Built-In Red Contrast Filter

Instead of a solid ND filter, the GR IV Monochrome incorporates a built-in red contrast filter within the lens unit, selectable via the rear On/Off button.

This filter allows only red wavelengths to reach the sensor, producing:

• Dramatic outdoor scenes with darkened skies and bright clouds

• Brightened skin tones and enhanced rendering of reddish subjects

Monochrome Image Control Modes

Two new Image Control options have been added to optimize monochrome output:

• Solid: Uses a hard tonal curve for a clean, bold, high-contrast look

• Grainy: Introduces a pronounced grain effect reminiscent of traditional darkroom prints while preserving highlight and shadow detail
