Introduction

The Canon EOS R6 Mark III is a mid-range full-frame mirrorless camera which replaces the EOS R6 Mark II that was released in 2023.

The R6 III utilises a new 32.5 megapixel CMOS sensor which provides a 25% increase in resolution compared to its 24.2 megapixel predecessor as well as offering 7K 60p internal RAW video recording.

It offers a class-leading burst shooting rate of 40fps using the electronic shutter with continuous auto-focus and auto-exposure or 12fps with the mechanical shutter, matching the range-topping EOS R3.

Pre-continuous shooting up to 20 frames (Raw or JPEG/HEIF) is available before fully pressing the shutter button. The 150 shot uncompressed RAW buffer (when using CFexpress cards) is double that of the R6 Mark II.

There is up to 8.5-stops of image stabilisation available via a combination of the camera's in-body Image Stabiliser which works in tandem with the attached lens’s own stabilisation system.

The native ISO range runs from 100-51200, which can be expanded to ISO 50-102400.

It supports internal RAW video recording at up to 7K 60P or 7K/30p with Open Gate turned on, high frame rate recording at up to 4K 120P / 2K 180P, oversampled 4K/60p and also 4K/60p UVC live streaming for the first time ever on a full-frame EOS camera.

Other video-centric features include waveform monitor, proxies, metadata tagging, a full size HDMI port, 4 channel audio, 3/5 sec pre-recording function, 15+ dynamic range and CLog 2 and 3 profiles.

Note that there is no built-in fan like the EOS C50 and this camera doesn't support the fan accessory that was released alongside the EOS R5 II.

Canon’s Dual Pixel CMOS AF II technology with improved tracking algorithms offers high-speed, high-accuracy subject detection and tracking for people, animals and vehicles down to -6.5EV.

The Registered People Priority mode can detect and prioritise up to 10 faces even in side profile, useful for sports, news and weddings, with the ability to save 10 files on a memory card each with 10 registered faces.

Just like on the R5 II and R1, you can recall AF settings on the Canon R6 III by registering up to six custom AF setting profiles to save time on pre-shooting setting configuration.

The Canon R6 III is identical in size to the Mark II but slightly heavier, weighing in at 699g with battery and memory card or 609g body only.

In terms of connectivity, the camera features 5GHz wi-fi and Bluetooth 5.1 support, a MIC terminal, HDMI OUT (Type-A) and USB (Type-C), plus dual CFexpress and SD card slots.

It employs the LP-E6P battery from the EOS R5 II which provides 620 shots according to CIPA standards.

The Canon EOS R6 Mark III is available in black priced at £2799.99 / €3199.99 / $2,799.00 body only in the UK, Europe and USA respectively. It is also available in a kit with the RF 24-105mm F4-7.1 IS STM lens for £3149.99 / €3599.99 / $3,149.00 or with the RF 24-105mm F4L IS USM lens for £3899.99 / €4199.99 / $4,049.00.

The R6 III is available to buy from November 20th 2025. It is made in Japan. Note that the R6 II will continue to be sold through-out 2026 whilst stocks last.
