What is the sensor size of the Canon SX730?

The Canon PowerShot SX730 HS is a digital camera that has a 1/2.3-inch sensor at its core. This imager measures 6.17mm in width and 4.55mm in height, so that the total imaging area of the sensor amounts to 28 mm².

The SX730 provides an image resolution of 20.2 megapixels, based on 5 184 horizontal pixels and 3 888 vertical pixels.

Sensor size comparison with a film slide

The sensor diagonal measures 7.7mm, which gives rise to a format factor (or crop factor) of 5.6. Hence, the Canon SX730 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 Canon SX730 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.
