Unlike its predecessors (the "GR Digital" series), the Ricoh GR incorporated an APS-Cimage sensor, while retaining a relatively compact form 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.[1]
An unusual feature of the Ricoh GR was its built-in ND filter. Its maximum shutter speed was variable, depending on the aperture setting (ie, 1/4000s was only available at apertures smaller than f/5.6).[1]
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 (28mm).
Ricoh GR II
DPReview 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".[2]
New features
802.11/Wi-Fi – to remotely control the camera as well as providing the option to transfer images from the camera to a mobile device or computer[2]
The internal flash can be used to remotely operate Pentax AF360 and AF540 flashguns as slaves[2]
Tap (half-press) the shutter to enter shooting mode if the camera has been turned on by holding the playback button, which previously required a full press[2]
Ricoh GR III
The Ricoh GR III was announced as "under development" on September 25, 2018, immediately prior to Photokina that year.[3] The camera was released in March 2019.
While the GR II was seen as an incremental upgrade,[2] 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. As July 30, 2020, a new firmware version was released.[4]
New features
Sensor resolution increased from 16 MP to 24 MP[5]
Minimum focusing distance improved to 6cm from 10cm[12]
Video recording frame rate improved to 60 fps at 1080p (Full HD)[5]
USB-C connectivity that can be used to charge the battery[13]
Ricoh GR IIIx
The Ricoh GR IIIx was announced in September 2021.[14] The camera was released the same month. An incremental update from the GR III, the GR IIIx includes a new 26.1mm lens.[15]
Ricoh GR IV
The updates to the GR IV were seen as rather incremental, as it retained most of the GR III's styling and features with numerous small changes and updates.[16]
New features
New 25.7 MP backside-illuminated sensor, up from the GR III's front-illuminated 25 MP sensor[16]
Redesigned lens (7 elements, 5 groups) with faster startup time and improved dust resistance[16]
