Canon EOS R3 vs Canon EOS R6 Mark II
The bottom line
There's a real price gap here: the Canon EOS R6 Mark II at $1,999 versus the Canon EOS R3 at $5,999. The question is whether those advantages are ones you'll use often enough to justify the premium — if not, the cheaper body is the smart buy.
Choose the Canon EOS R3 if…
- ✓You shoot video seriously — it brings smoother 120p 4K vs 60p.
- ✓You shoot in low light or indoors — AF that focuses down to -7.5 EV gives it the edge after dark.
Choose the Canon EOS R6 Mark II if…
- ✓You shoot action, sports or wildlife — 40fps burst keeps up with fast, erratic movement where 30fps would drop frames.
- ✓You're budget-conscious — it launched at $1,999, about $4,000 less, freeing money for lenses.
- ✓You value portability — at 588g (1.30 lb) it's noticeably lighter than the 1015g (2.24 lb) alternative for travel and all-day carry.
- ✓You need backup-while-you-shoot reliability — dual card slots (the other has one) matter for paid work like weddings and events.
