Canon's latest enthusiast full-frame mirrorless with 24.2MP, advanced AF, and 8K video capability.
The Canon EOS R6 Mark III was released in November 2025 as Canon's third-generation professional hybrid RF mirrorless body, advancing the 32.5MP full-frame CMOS sensor with 40fps electronic shutter burst and a 20-frame pre-capture buffer — preserving the 20 frames immediately before the shutter is fully pressed, for action sequences where the decisive moment precedes the trigger response. 7K RAW Light internal video recording uses a Canon Cinema EOS-derived codec at 12-bit. 4K at up to 119.8fps enables 5× slow motion at full 4K resolution.
The 32.5MP full-frame CMOS sensor pairs with deep-learning subject detection AF derived from Canon Cinema EOS development. Electronic shutter burst runs at 40fps; mechanical and EFCS run at 12fps. 7K RAW Light records internally at 12-bit; 4K oversampled from the full sensor at up to 60fps is also available; 4K at 119.8fps provides high-speed video capability. Canon Log 3 is supported. Dual card slots. Weather and dust sealing is built throughout. Body weight 609g (body only), 699g with battery and one card. Battery: LP-E6P (LP-E6NH compatible with reduced functionality).
The 20-frame pre-capture buffer is the R6 Mark III's most novel feature: it continuously stores the previous 20 frames in a rolling buffer, capturing the action sequence leading up to the moment the shutter fires. This addresses a fundamental sports and wildlife challenge — the gap between observing and capturing peak action. The 7K RAW Light internal recording brings Cinema EOS codec quality to a hybrid body format without requiring an external recorder.
The R6 Mark III is a November 2025 product with no used market availability at time of writing. As a new release, buyers should purchase new or from authorised dealers initially. Condition checks when used examples become available: pre-capture buffer function, both card slot contacts, weather sealing, and battery health. Compatible with all Canon RF-mount lenses.
