What is the sensor size of the Ricoh GR III?

The Ricoh GR III is a digital camera that has an APS-C sensor at its core. This imager measures 23.5mm in width and 15.6mm in height, so that the total imaging area of the sensor amounts to 367 mm².

The GR III provides an image resolution of 24 megapixels, based on 6 000 horizontal pixels and 4 000 vertical pixels.

Sensor size comparison with a film slide

The sensor diagonal measures 28.2mm, which gives rise to a format factor (or crop factor) of 1.5. Hence, the Ricoh GR III is a crop-sensor camera, as its sensor is smaller than a traditional 35mm film slide or negative.

Sensor specs and performance

The table below compares the sensor specs of the Ricoh GR III to those of several similar cameras. The reported DXO values are indicators of the sensor's imaging quality (higher is better), covering color depth (DXO Portrait), dynamic range (DXO Landscape), and high-ISO noise (DXO Sports). Larger sensor cameras tend to outperform cameras of the same generation that are equipped with a smaller imager. On the other hand, larger sensors are more expensive and require bigger and heavier lenses than smaller light receptors.
