EOS R5 Err 70

MBP
Apprentice

I just received a new EOS R5 and out of the box I was getting an err 70 lockup. I thought updating the firmware would resolve the problem but the err 70 continues. I have now received a message 20 or 25 times over the course of 100 frames. Is the a comen problem?

Greetings,

Please follow the recommendations in my post above (2-25-2024).  If exchange is still an option, I'd do that.

Agree completely.  Never tolerate OBF (out of box failures) of any product for any reason.  Get a new one!

I am using canon RF 24-70 2.8 , RF 50mm 1.8, RF 70-200 2.8.

Same issue with all lenses.
