TOKYO, October 20, 2025 — RICOH IMAGING COMPANY, LTD. is pleased to announce the development of the RICOH GR IV Monochrome. It is the first model in the high-end GR compact digital camera series designed specifically for black and white photography.
The RICOH GR IV Monochrome, which is currently in development, is based on the latest model, the RICOH GR IV, which was released in September 2025. It is equipped with a new, dedicated monochrome image sensor and Image Control options specialized for black and white photography to deliver the expressiveness and depth unique to monochromatic images.
It has been nearly 30 years since the RICOH GR1 film camera, the first in the GR series, was released in 1996, and exactly 20 years on October 21 since the GR DIGITAL was launched in 2005.
Over the history of this series, our commitment to the essential camera values of high image quality, quick response and portability has always remained the same. Hinging on these basic concepts, the GR series has continued to evolve to meet the needs of the times. We hope you are excited about the RICOH GR IV Monochrome and this new foray into black and white territory.
