Canon EOS R6 Mark III review
Thirty two point five megapixels with 8.5 stops of stabilisation, and a CFexpress Type B slot that costs real money to fill.

What it does well
- Thirty two point five megapixels is the right resolution for a hybrid. Enough to crop and print properly, not so much that file sizes and low-light performance suffer.
- Pre-continuous shooting captures 20 frames before you fully press the shutter, which is the feature that turns missed moments into captured ones in sport and wildlife.
- Eight and a half stops of stabilisation is exceptional, and it is what makes handheld video and low-light stills possible without a tripod.
- Dual Pixel CMOS AF II with subject detection and Register People Priority is among the most reliable autofocus systems available, and it is the reason many people stay with Canon.
- Dual card slots with different formats means a fast card for burst and video and a cheap card for backup, which is how professionals actually work.
Where it falls short
- The CFexpress Type B slot is expensive to fill. Those cards cost several times what a good SD card does, and the camera's highest performance modes want one.
- Mixed card formats means you cannot simply mirror to two identical cards, so your backup strategy has to account for two different speeds and capacities.
- Forty frames per second is electronic shutter territory, and electronic shutters on most sensors have rolling shutter behaviour with fast motion and artificial light. Check how it behaves with your subjects before relying on it.
- Very high burst rates fill cards and hard drives at a rate people underestimate. Forty frames a second is an editing workload as much as a capture capability.
- It is a hybrid, which means it is not the best stills camera or the best video camera at the price. For pure low-light video, a video-first body does that job better.
What owners report
Canon's R6 line has an unusually strong reputation as the do-everything full-frame body, and owner reports focus on the autofocus and the stabilisation as the features that change how you shoot. The recurring practical complaint across cameras with CFexpress Type B slots is card cost, which is a real budget item rather than a grumble.
Our best mirrorless camera guide covers the field and our Sony versus Canon comparison covers the two systems most hybrid buyers choose between, which is a lens ecosystem decision as much as a body one.
Test it on arrival with our mirrorless testing guide, which covers sensor inspection, shutter behaviour and the checks worth doing while the return window is open.
Who it suits
- Anyone who needs one camera to shoot both stills and video properly.
- Sport, wildlife and event shooters, where pre-continuous capture and 40 fps genuinely help.
- Photographers working handheld in low light, where 8.5 stops of stabilisation is transformative.
Who should skip it
- Pure video shooters in very low light, where a video-first body with larger pixels is better.
- Anyone on a tight budget who has not accounted for CFexpress Type B card costs.
- Photographers needing very high resolution for large prints or heavy cropping.
Alternatives worth considering
Twelve megapixels, ISO to 409,600 and 4K120 in 10-bit 4:2:2 internally. Far better in low light for video and a poor stills camera, which is the trade its 12 megapixels buys.
Check price on AmazonThe generation before, at seven hundred dollars less, with 24.2 megapixels. Still an excellent hybrid body, and worth checking against the Mark III's improvements before paying the difference.

What is pre-continuous shooting?
The camera continuously buffers frames while the shutter is half pressed and saves the 20 frames before you fully pressed it. In practice it means the shot you reacted a fraction too late for is still in the file. For sport and wildlife it is one of the most genuinely useful features to arrive in recent years.
Do I need a CFexpress Type B card?
For the camera's highest performance modes, yes, and those cards cost several times what a good UHS-II SD card does. The second slot takes SD, so you can run one fast card and one cheaper backup. Budget for at least one Type B card as part of the purchase.
Is 32.5 megapixels enough?
For almost everything short of large commercial print and heavy cropping, comfortably. It sits in the sweet spot for a hybrid body: enough resolution to crop meaningfully, small enough that file sizes and low-light performance stay reasonable.
How useful is 8.5 stops of stabilisation?
Very. It is the difference between needing a tripod and not, both for low-light stills and for handheld video. The figure is measured at the centre of the frame with 7.5 stops at the periphery, and real-world results depend on the lens and your technique.
Canon or Sony for a hybrid camera?
Both make excellent bodies at this level. The decision is really about lenses, because the glass outlasts the body and moving systems is expensive. Canon's autofocus and colour science have devoted followings; Sony's lens selection and video features have theirs. Our comparison covers both.
