On October 21, RICOH Imaging Company announced the development of two derivative models based on the compact digital camera 'RICOH GR IV': the 'GR IV Monochrome' and the 'GR IV HDF.' Both models are custom-designed to specialize in snap photography and pursue unique rendering characteristics.

The First GR Series Camera with a Dedicated Monochrome Sensor

The 'GR IV Monochrome' features a dedicated monochrome CMOS sensor, a specialized lens unit, and image control. Designed to maximize the gradation and texture of black-and-white photography, it offers a new photographic experience not seen in previous GR models. The release is scheduled for spring 2026.

The 'HDF Model' for Soft Highlight Rendering

The 'GR IV HDF' incorporates a Highlight Diffusion Filter (HDF) instead of the conventional ND filter. This allows for soft rendering that takes advantage of light diffusion and supports switching the filter ON/OFF. The HDF effect, which gained attention with the GR III, has been updated for the latest model, scheduled for release in winter 2025.
