Canon releases statement on EOS R5 and R6 video heat management

Canon has released a statement on how heat is managed in its new EOS R5 and R6 mirrorless cameras, as well as clarification on video recording times.

Canon EOS R5 and R6: Shooting times for video modes

Canon UK & Ireland: The highly anticipated Canon EOS R5 and EOS R6, two advanced full frame mirrorless cameras, offer a combination of speed and resolution to set new standards and make mirrorless an ideal choice for everyone from wedding to wildlife photographers.

EOS R5 and EOS R6 offer powerful stills and movie recording capabilities within compact body designs, allowing photographers and filmmakers to push creative boundaries harder and capture action better than ever before. At the highest frame rates and resolutions, heat is generated because of the best-in-class resolution, frame rate and autofocus capability, which can limit continuous recording times.

Several steps have been taken to manage this; magnesium alloy is used in the body to dissipate heat away from internal components and there is an ‘overheat control’ function to reduce heat generation when the camera is in standby. To maintain the level of weather sealing and retain a compact design, an internal fan has not been installed.

Before recording starts, EOS R5 and EOS R6 display an estimate of the recordable time based on the current camera temperature and the set recording mode. Approximate recording and recovery times for 23°C / 73°F environments are available so that customers will be able to decide how to best utilise each mode:

Model	Resolution and frame rate	Mode	Approx. shooting time (23°C / 73°F)^*1	Recommended scene
EOS R5	8K 30p	Full Sensor Width	20min	8K productions where a full frame mirrorless can be utilised to get unique angles alongside a main camera or additional cropping for 4K productions
	8K 30p	Full Sensor Width RAW	20min	As above but with the additional workflow flexibility of RAW
	4K 120p	Full Sensor Width	15min^*2	Shorter bursts of slow motion
	4K 60p	Full Sensor Width	35min^*3	High frame rate high resolution productions and independent films
	4K 60p	APS-C Crop (5.1K Oversampled)	25min	When additional reach is required with higher frame rates – e.g. wildlife and sports and news gathering within a 4K production or even for tighter Full HD crops in post
	4K 30p	Full Sensor Width	Not limited by heat	Interviews, longer duration capture such as weddings
		Full Sensor Width High Quality (8.2K oversampling）	30min	When additional resolution is required with a 4K30p production or for a Full HD workflow where cropping can be desirable with high resolution
		APS-C Crop (5.1K oversampled)	Not limited by heat	When additional reach is required – e.g. wildlife and sports and news gathering within a 4K production or even for tighter Full HD crops in post
EOS R6	4K 60p	94% sensor width (5.1K oversampling)	30min	Independent films shooting action or with the option of slow motion at high resolution
	4K 60p	APS-C Crop	35min^*3	Independent films shooting action at high resolution with the need for additional reach for sports or wildlife or tighter crops
	4K 30p	94% sensor width (5.1K oversampling）	40min^*3	General purpose

Estimated camera recovery times are indicated below. The time until full record time is available will vary with ambient temperature, continued camera operation and the selected shooting resolution.

Model	Resolution and frame rate	Waiting period (23°C / 73°F)	Approx. max recording time after waiting period
EOS R5	8K 30p	10min	3min
	8K 30p	20min	8min
	4K 60p	10min	10min
EOS R6	4K 60p	10min	5min
