Sony Alpha 7R review – Dynamic range
Image: This edited raw image shows that detail can be recovered from dark shadows
The Alpha 7R has a moderate dynamic range of 12.2EV at ISO 100, which is understandable given the pixel density of the sensor. With 36.3 million photosites on the surface of the sensor, each one will receive less light that a comparable 24, 16 or 12-million-pixel, full-frame sensor.
As a result, the dynamic range will always be less, although that is not to say it is poor. Raw files can be edited to around +2EV exposure before luminance and colour noise become too much of an issue, and there is usually plenty of detail that can be revealed in shadows. Similar is true for highlight areas.
