UPDATE: Canon has now issued a fix for the defective Canon EOS R6 v1.3 firmware, in the form of firmware v1.3.1, which is available now. 

The latest download for the Canon EOS R6 adds a new, seventh update to the six points in the previous firmware, to correct the problem issue: "7. Fixes a phenomenon, in which the camera stops to operate normally when the movie cropping setting is set to [Enable] for performing movie shooting in Firmware Version 1.3.0."

Download firmware v1.3.1 for the Canon EOS R6. 

ORIGINAL STORY: After being available for less than a day, the latest firmware for the Canon EOS R6 has been removed by Canon and is no longer available. It appears that the firmware is causing specific issues when using 1080p / FullHD in 100 or 120p mode in conjunction with EF-S lenses or cropped shooting. 

The Canon EOS R6 received the latest firmware, version 1.3, only yesterday, along with major firmware updates to both the Canon EOS R5 and Canon EOS-1D X Mark III. However, while the other two bodies seem to be unaffected in any negative way by the new firmware, the same seemingly can't be said for the R6.

As reported by Canon Rumors, Canon sites around the world pulled the new EOS R6 firmware yesterday – and apparently also removed promotional material regarding the firmware update. 

"Unfortunately the latest firmware version 1.3.0 for the EOS R6 is temporarily unavailable," states the official Canon UK support page for the R6, which hosts firmware updates for the camera. "We anticipate the firmware being available in the near future so please check back soon for your download."

While many people won't have installed the firmware yet, those that have are finding that they can't roll it back – such as Twitter user VicPlacido83 – and are stuck with the defective update. 

A video was posted on Chinese site Billbill by 蛋卷肉丝丶 titled "Canon R6 latest 1.3.0 firmware fatal bug, upgrade carefully" demonstrating that the camera becomes unresponsive. It displays the Err 70 error message, which according to Canon means "An image related malfunction has been detected." However, since the video is in Chinese, it was down to a Twitter user to translate the issue.

"According to Bilibili video, the bug would affect when using 1080 100/120p mode with either EFS lenses or crop mode," tweeted c10_65. "do NOT use high framerate and crop mode together. Factory reset could solve the problem and photo mode is not affected."

We will update this story as soon as there is a fix for affected cameras, or replacement firmware becomes available.
