Canon product advisory for Error 70 or 80 on Canon EOS 70D

We would like to offer our sincere apologies to users who have been inconvenienced by the phenomenon described below. We value the trust our customers have placed in us, and we are dedicated to continuously improving product quality as well as delivering industry-leading service and support.

In rare cases, error 70^*1 or error 80^*1 may repeatedly display on some EOS 70D digital SLR cameras due to an internal communication failure resulting from the structure of the electrical printed circuit board. If use of the camera is subsequently continued, a state may occur in which the camera’s power does not turn on. In most cases, this phenomenon occurs in conjunction with continuous use of the camera while the camera’s internal temperature is high, such as when shooting movies continuously.

“Err 70” or “Err 80” will appear on the LCD monitor at the back of the camera or on the LCD panel at the top of the camera.

^*1There may be rare occurrences of error 70 or error 80, after which the camera functions can be recovered by turning the power off and on again, or by re-installing and reinserting the battery. The phenomenon described here refers to the frequent reoccurrence of error 70 or error 80.
