The Ricoh GR is a digital large sensor compact camera announced by Ricoh on April 17, 2013, one of a number of Ricoh GR digital cameras. It was succeeded by the Ricoh GR II in 2015 and the Ricoh GR III in 2018.
Ricoh GR
Unlike its predecessors, the Ricoh GR incorporated an APS-Cimage sensor, while retaining a relatively compactform factor. Coupled with its retractable lens, the GR is potentially the slimmest of any camera in its class when powered off. Aside from portability, reviewers praised the GR for its lens quality and ergonomics. An unusual feature of the Ricoh GR was its built-in ND filter. Its maximum shutter speed was variable, depending on the aperture setting. The Ricoh GR series has been compared against the Nikon Coolpix A and the Fujifilm X70, other large sensor compacts with the same fixed focal length.
Ricoh GR II
said that over the Ricoh GR, the GR II is "a fairly minor update... the camera isn't a dramatic update... the core of the camera remains the same".

Ricoh GR III
The Ricoh GR III was announced as "under development" on September 25, 2018, immediately prior to Photokina that year. The camera was released in March 2019. While the GR II was seen as an incremental upgrade, the GR III was the result of a longer development cycle and boasted more significant changes. Ricoh indicated that several key components, including the sensor and the lens, would be upgraded. The body dimensions would decrease slightly, with the built-in flash removed.
