Canon EOS R vs Canon EOS R6 Mark III
The bottom line
Same line, different generation: the Canon EOS R6 Mark III (2025) moves ahead on burst speed (40fps vs 8fps), 4K frame rate (120p vs 25p) and in-body stabilisation. The Canon EOS R is still the value pick at $2,299 ($2,799 for the Canon EOS R6 Mark III). If those newer features aren't ones you'll actually use, the Canon EOS R gives you most of the experience for less.
Choose the Canon EOS R6 Mark III if…
- ✓You shoot action, sports or wildlife — 40fps burst plus dedicated subject-tracking AF keeps up with fast, erratic movement where 8fps would drop frames.
- ✓You shoot video seriously — it brings smoother 120p 4K vs 25p, 10-bit internal colour, Log for gradable footage, no per-clip recording limit (vs a 29-min cap) and both mic and headphone jacks for monitored audio.
- ✓You shoot handheld — in-body stabilisation lets you use slower shutter speeds and steadies video, which the other body can't do without a stabilised lens.
- ✓You vlog or shoot handheld solo — the fully-articulating screen flips to face you and there's a mic input for clean audio.
