Canon EOS R5
The Canon EOS R5 is a full-frame mirrorless interchangeable-lens camera officially announced by Canon on July 9, 2020 alongside the lower-resolution EOS R6 and various new RF mount lenses. While it is not a direct successor to any of Canon's previous mirrorless cameras, it does have clear improvements and advantages over the EOS R, namely: a new DIGIC X processor and sensor, 8K video capture, a new autofocus system, and the ability to take videos with 10-bit colours. The camera is available as body only, or with the Canon RF 24 -105mm f/4L IS USM lens. Reception. Overheating issues. Shortly after the EOS R5's initial announcement, concerns arose about issues of overheating while recording video, especially 8K video, after short periods of time. In response to users' complaints, Canon issued a media alert addressing these overheating issues, including how long it will take for the camera to overheat at each resolution, why a fan was not included, and how users can prevent the camera from overheating. According to Canon's reported data, the EOS R5 will begin to overheat after recording for just 20 minutes at 8K  resolution. A fan was not included to preserve its compact size. Users can delay overheating by toggling on "Overheat Control" in settings, which will adjust resolution and frame rate automatically to prevent overheating. Although Canon offered this explanation, users have continued to complain. Other testers, however, discovered continuous shooting is possible for up to four hours in 4KHQ mode with an external recorder if no memory cards are inserted, the screen is off, and a dummy battery is used. With an actual battery, again overheating can be avoided for the life of the charge of the battery, about an hour  45 minutes. The Canon R5's overheating problem was solved in Canon EOS R5 C, the hybrid between EOS R and EOS C series announced in January 2022.
