UPDATE 8/1: Canon has re-issued the firmware update. Just as was the case this time, Canon removed the initial 1.3.0 update without explanation while it worked on the fix, which came in the form of firmware update 1.3.1. That issue was fixed within 24 hours of the company’s initial firmware update. When the issue came up, the camera exhibited an “Err 70” warning.

That bug caused the camera to lock up upon restart - which was demonstrated by a user in China - after initiating certain video modes in APS-C crop mode. Last year, Canon released a firmware update for the R6 mirrorless camera that introduced a Full HD video recording bug. Issues with firmware like this are not common, but they have happened. The R3 firmware update version 1.2 added a total of 14 updates including the two noted changes above including several new features and a host of minor bug fixes. The update also updated video performance, which allowed the camera to shoot Full HD video at up to 240p, which Canon said is usually a framerate reserved for dedicated video cameras.
