Spec figures from the makers: Canon EOS R6 Mark II (canon-europe.com, checked 25 Sept 2026) · Canon EOS R6 Mark III (canon-europe.com, checked 25 Sept 2026)
This is where the generation actually changes: Canon's own figure for the Mark III is 32.5 megapixels against the Mark II's 24.2, a third more linear resolution. Neither sensor is stacked.
Winner: Canon R6 Mark III, on resolution. What it cuts shutter — but for stills the difference is subtle.
This is where the generational gap is most obvious:
Winner: Canon R6 Mark III, decisively. Internal 7K RAW, C-Log2, and a full-size HDMI port make it a genuine cinema tool.
Both cameras hit 40fps electronic / 12fps mechanical with pre-capture, so raw frame rate is a wash. The Mark III refines the experience around it:
Winner: Canon R6 Mark III by a small margin — both are superb, but the III holds focus better in the dark and buffers deeper.
The Mark III addresses the Mark II's two main hardware limits:
Winner: Canon R6 Mark III. CFexpress unlocks the buffer and 7K RAW.
If you already own the R6 Mark II: Don't upgrade for stills alone — burst speed and AF are essentially the same. Upgrade only if you genuinely need 7K RAW video, CFexpress workflow, or the better low-light AF.
If you're buying new: The R6 Mark III is the better camera and the one to get if video matters. But the R6 Mark II remains a phenomenal value for photo-first shooters.
Both bodies deliver pro-quality results. The "wrong" pick here still out-shoots almost everything else in the price class.
