What is the sensor size of the Sony A7R?
The Sony Alpha A7R is a digital camera that has a full frame sensor at its core. This imager measures 35.9mm in width and 24.0mm in height, so that the total imaging area of the sensor amounts to 862 mm2.
The A7R provides an image resolution of 36.2 megapixels, based on 7 360 horizontal pixels and 4 912 vertical pixels.
Sensor size comparison with a film slide
The sensor diagonal measures 43.2mm, which gives rise to a format factor (or crop factor) of 1.0. Therefore, the Sony A7R 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 A7R 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.
