Canon Clarifies EOS R5 and R6 Video Shooting Times

July 20, 2020 | Mark Goldstein | Compact System Camera | Comment |

In response to some rather "heated" internet criticism about overheating during video recording, Canon have taken the unusual step of issuing an official media advisory about the video shooting times of the upcoming EOS R5 and EOS R6 mirrorless cameras.

Canon EOS R5 and EOS R6: shooting times for video modes

United Kingdom, Republic of Ireland, 14th July 2020 – 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:

1 Time available for continuous shooting in 23°C / 73°F environment, from a cold start. If the camera is in LV mode standby before shooting or the ambient temperature is high, the shooting time may be shorter.

2 Recording stops at 7minutes and 30seconds for high frame rate video. Indicates the time when recording can be resumed immediately.

3 Recording is limited to 29 minutes 59seconds. Indicates the time when recording can be resumed immediately.

Subject: Details Regarding Canon EOS R5/EOS R6 Overheating During Video Recording

The EOS R5, one of the latest additions to Canon’s full-frame mirrorless camera line, offers class-leading autofocus with high-resolution and high frame rate video recording options using the maximum width of the full-frame sensor at high bit rates. Inevitably, this combination of features has potential to generate some significant heat, which will limit recording time.

Canon has taken several steps to manage the potential for overheating, including:

  • Magnesium alloy was used in the body to dissipate heat away from internal components
  • An “overheat control” function to reduce heat generation when the camera is in standby

In regard to the installation of a fan: The decision not to install a fan within the body was made in order to maintain the EOS R5’s compact size, lightweight construction and weather resistance.

Before recording starts, the EOS R5 and EOS R6 display an estimate of the recordable time based on the current camera temperature and the set recording mode.

Canon has published and included below the approximate recording and estimated recovery times for 23°C / 73°F environments and ensure that the camera will warn users when it is getting too hot. Additionally, tips to reduce overheating as well as recovering time are listed below.

How can you reduce heat buildup in the EOS R5?

  • Set Overheat Control function to "ON" (default). When the overheat control function is enabled, the movie size and frame rate are automatically changed while the camera is in standby mode to suppress the rise of the internal temperature
  • Between recordings, it is recommended to turn off the camera
  • Position the camera out of direct sunlight
  • Use an external fan to dissipate heat

How long will it take for the camera to recover?

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.

What about the EOS R6?

Like the EOS R5, the EOS R6 offers powerful movie recording and stills capabilities within a compact body design. At the highest frame rates and resolutions heat is inevitably generated. We believe the EOS R6 offers best in class performance, especially for enthusiast photographers and video content creators.

The EOS R6 can record up to the 29 minutes 59 second recording limit in the 5.1K oversampled 4K 60p mode at (23°C / 73°F) before encountering any heat related issues within the camera and up to 40 minutes of 4K at 30p.
