Canon EOS R5 vs Canon EOS R6 Mark III
The bottom line
There's a real price gap here: the Canon EOS R6 Mark III at $2,799 versus the Canon EOS R5 at $3,899. The extra buys you 8K video and 45MP of resolution. 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 R5 if…
- ✓You shoot video seriously — it brings 8K capture (up to 30p).
- ✓You want maximum detail for landscapes, studio or large prints — 45MP resolves noticeably more than 32.5MP and gives more cropping latitude.
Choose the Canon EOS R6 Mark III if…
- ✓You shoot action, sports or wildlife — 40fps burst keeps up with fast, erratic movement where 12fps would drop frames.
- ✓You're budget-conscious — it launched at $2,799, about $1,100 less, freeing money for lenses.
- ✓You shoot in low light or indoors — a higher native ISO ceiling (102,400) and AF that focuses down to -7 EV give it the edge after dark.
- ✓You need backup-while-you-shoot reliability — dual card slots (the other has one) matter for paid work like weddings and events.
