How much dynamic range does the Canon G7 X Mark III offer?

The sensor in the Canon PowerShot G7 X Mark III is estimated to provide 12.4 EV of dynamic range (DR). While no actual measurement of DR is available for the G7X Mark III, an estimate can be derived based on assessments of other cameras that have sensors of similar size and age. A DR-value of 12 EV or above is considered excellent.

High dynamic range of a camera sensor is particularly desirable for scenes with a mix of very bright and very dark parts, such as in some landscape photography settings. It helps to avoid that highlights get washed out or that detail in shadows is lost.

Sensor specs and performance

The table below compares the sensor specs of the Canon G7 X Mark III to those of several similar cameras. The reported DXO values are indicators of the sensor's imaging quality (higher is better). In addition to dynamic range (DXO Landscape), the listing also covers color depth (DXO Portrait) 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.
