The The Mark III features a new sensor with Dual Gain OUtput - which results in a wide, clean dynamic range, along with internal raw recording. It also shares the same body as the C500 Mark II, including electronic image stabilization, interchangeable lens mounts, and optional expansion units, but requires only half the power draw. DGO is only available up to 60p in S35 mode, or up to 112p in S16
