Why you can trust TechRadar
Dynamic range is a measure of the camera's ability to record a wide brightness range while still capturing detail in the shadows and highlights. It's measured in EV (exposure values) and the higher the figure the better. We test dynamic range in laboratory conditions using DxO Analyzer hardware and software, and check both JPEG and raw files across a wide ISO range.
JPEG dynamic range analysis: The figures for all four cameras are very close here, right up to ISO 800, but from ISO 1,600 onwards the A68 does start to pull away from the rest.
Raw (converted to TIFF) dynamic range analysis: The raw files deliver a slightly different result and here the A68 holds its own from ISO 800 onwards but is beaten by the Nikon D5500 at lower ISOs.
