As we’ve seen, the cameras do record to Canon’s claims, but with the same huge caveat. You only get these times from a completely cooled camera. So that means the times change when you use LiveView, shoot stills, or shoot any shorter length of video, doing that over and over will eventually lead to overheating. The EOS R5 took about an hour in the DPReview test to get back to normal temperature. The surprising thing DPReview found, is that the EOS R6 will generally record longer, but it takes longer to cool down.
DPReview gives a few suggestions for maximizing your recording time with both the Canon EOS R5 and Canon EOS R6.
EOS R5 suggestions:
- Expect to shoot line-skipped 30p for the bulk of your footage
- Only use 8K or oversampled HQ 4K for occasional B-Roll
- 4K/120 and 8K will cut into your shooting time quickest of all
- Be aware of your setup time and cumulative usage (including stills shooting)
EOS R6 suggestions:
- Don’t expect to be able to shoot for extended periods
- Be aware of the need for extensive cooling periods between bursts of shooting
