RICOH GR IV Monochrome - Equipped with a dedicated monochrome image sensor for the ultimate in black and white expression & RICOH GR IV HDF - Equipped with the Highlight Diffusion Filter (HDF) for soft highlights

Tokyo, October 20, 2025 — RICOH Imaging is proud to unveil the development of the RICOH GR IV Monochrome, the first GR-series compact digital camera crafted exclusively for black and white photography.

Built on the acclaimed GR IV platform released in September 2025, this new model features a dedicated monochrome image sensor and refined Image Control settings tailored to capture the depth, emotion, and timeless beauty of monochromatic imagery.

Image Sensor: Monochrome, CMOS. Size: 23.3 x 15.5 (mm)

‍Effective Pixels: Approx. 25.74 megapixels

‍Sensitivity (Standard output): ISO160 to ISO 409600: Auto (ISO Auto Lower/Upper Limit and Minimum Shutter Speed can be set), Manual

The GR IV Monochrome is more than a camera—it’s a tribute to the art of seeing in black and white.

Along with the GR IV Monochrome — RICOH IMAGING COMPANY, LTD. is also pleased to announce the development of the RICOH GR IV HDF. This new model, based on the high-end RICOH GR IV compact digital camera, is equipped with the company’s proprietary HDF (Highlight Diffusion Filter).

The RICOH GR IV HDF, which is currently in development, is based on the latest GR series model, the RICOH GR IV. In addition to the existing sharp depiction performance, we have added our proprietary HDF (Highlight Diffusion Filter) which diffuses highlights and delivers soft photographic effects with the touch of a single button as a built-in feature. The conventional sharp expressiveness of the GR series and soft effects when the new HDF is activated provide an even greater range of snapshots that match the subject and the photographer's intentions.

Image Sensor Type: Primary color filter CMOS. Size: 23.3mm x 15.5mm

‍Effective Pixels: Approx. 25.74 megapixels

‍Sensitivity (Standard output): ISO100～204800: Auto (ISO Auto Lower/Upper Limit and Minimum Shutter Speed can be set), Manual

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. Launching in 2024, the RICOH GR III HDF and RICOH GR IIIx HDF were the first models to include HDF. This new feature added the ability to capture emotional photos to the existing sharp expressiveness, making them popular among many users since their release. We hope you are excited about the versatile expressive possibilities that the RICOH GR IV HDF has in store.
