How much dynamic range does the Sony A7 IV offer?
According to measurements carried out by DXO Mark, the sensor in the Sony Alpha A7 IV provides a maximum of 14.7 EV of dynamic range (DR). DR is defined as the ratio between the highest and lowest brightness a camera can capture. A 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 Sony A7 IV 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.
