Canon's professional cinema camera with Dual Gain Output sensor — 4K Super 35 for high-end production.
The Canon EOS C300 Mark III was released approximately 2020 as a professional cinema EOS body with a Super 35mm Dual Gain Output (DGO) sensor for 6K RAW internal recording. Cinema EOS body with EF and PL mount options. At approximately 1,700g body without lens. 15+ stop dynamic range.
Super 35mm DGO sensor (6K). 6K RAW (Cinema RAW Light) internal recording; 4K up to 120fps. 15+ stops dynamic range (DGO dual-pixel dual-ISO). XLR audio (×4). ND filter (2-10 stop built-in). Genlock/sync. EF Cinema mount (also available in PL). At approximately 1,700g body.
The DGO (Dual Gain Output) sensor is the C300 III's defining technology: each pixel reads simultaneously at two gain levels — standard and high gain — combining them to achieve extended dynamic range in a single pass without the motion artefacts of frame-by-frame dual-ISO switching. The built-in 2-10 stop ND filter enables consistent exposure in changing outdoor conditions without physical filter changes.
On the used market the Canon EOS C300 Mark III is available at professional cinema camera pricing. Condition checks: DGO sensor for dust/damage, EF mount contacts, built-in ND filter function, XLR audio inputs. Professional cinema EOS — requires EF Cinema or standard EF lenses.
