RICOH GR IV Monochrome Camera - 25.74MP APS-C Sensor, Built-In Red Filter

Ricoh Imaging proudly presents the RICOH GR IV Monochrome, a premium compact camera designed exclusively for black-and-white photography. Building on the acclaimed performance of the RICOH GR IV, this model combines exceptional image quality, lightning-fast response, and remarkable portability with a sensor optimized specifically for monochrome imaging. By removing the color filter and interpolation processes used in conventional color sensors, the GR IV Monochrome fully leverages the high-performance GR lens to deliver refined detail, rich tonal gradation, and expressive black-and-white imagery.

Monochrome-Dedicated Design

At the heart of the GR IV Monochrome is an anti-aliasing (AA) filterless APS-C CMOS image sensor with approximately 25.74 effective megapixels. Unlike typical color sensors that convert captured light through red, green, and blue filters and then interpolate a monochrome image, this dedicated sensor records brightness information directly from each pixel. This approach allows for sharper, more detailed images with nuanced tonal gradation. The sensor’s high sensitivity also enables photographers to create striking works that emphasize grain effects, adding a tactile, analog feel to digital monochrome photography.

Built-In Red Filter for Creative Control

The GR IV Monochrome features a red filter built into the lens unit that can be toggled on or off with a single action. By selectively allowing red wavelengths to pass, this filter produces dramatic effects, such as darkening blue skies to enhance cloud contrast or brightening red subjects for stronger visual. It offers photographers a simple yet powerful tool to enhance contrast and artistic expression in their black-and-white imagery.

Diverse Monochrome Expression Options

To expand creative possibilities, the camera includes monochrome-dedicated Image Control options. The “Solid” mode delivers a crisp, clean look with well-defined edges, while the “Grainy” mode evokes the texture and feel of classic silver-halide prints. Grain is clearly visible even on digital displays, and careful tonal handling prevents highlights from blowing out and shadows from crushing to solid black, resulting in expressive, versatile monochrome images.

Carefully Crafted Exterior Design

The GR IV Monochrome is as aesthetically refined as it is functional. Its magnesium-alloy body, shutter release button, and ring cap are finished in matte black, evoking the elegance of traditional black-and-white photography. The front GR logo is rendered in semi-gloss black for subtle contrast, and the white illumination of the power button complements the overall monochrome theme. The subdued sheen, deep texture, and soft tactile feel make the GR IV Monochrome visually and physically distinct.

Additional Features

The camera also includes an electronic shutter capable of speeds up to 1/16000 second, allowing high-speed shooting in bright conditions and creative aperture control even under intense light. This function enhances the high-sensitivity capabilities of the monochrome sensor and is scheduled to be added to the standard GR IV via future firmware. Aside from the absence of the ND filter, the GR IV Monochrome shares the same specifications as the original RICOH GR IV.
