What is the sensor size of the Sony A7S III?
The Sony Alpha 7S III is a digital camera that has a full frame sensor at its core. This imager measures 35.6mm in width and 23.8mm in height, so that the total imaging area of the sensor amounts to 847 mm2.
The A7S III provides an image resolution of 12 megapixels, based on 4 240 horizontal pixels and 2 832 vertical pixels.
Sensor size comparison with a film slide
The sensor diagonal measures 42.8mm, which gives rise to a format factor (or crop factor) of 1.0. Therefore, the Sony A7S III is a full-frame camera, as its sensor size corresponds to that of a traditional 35mm film slide or negative.
Sensor specs and performance
The table below compares the sensor specs of the Sony A7S 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.
