The built in flash on 80D pops up in Auto mode but won't fire. I put "built in flash on" in the on mode and it will pop up but not fire. I have been using 430EXIII RT and everything has been working fine. Been shooting in P mode and built in flash and 430 have been working well. Not sure if I have pressed the wrong button or what but I sure do need some help. Thanks in advance.
Follow the update instruction carefully from Canon website.
Hope it will help after firmware updated.
First check to see what firmware your camera currently has. You may already have 1.0.2 installed. Early 80Ds had version 1.0.1 and there was a firmware update to 1.0.2 which would have been factory installed on later 80Ds.
If you are comfortable with the upgrade process, then go ahead, but there is nothing in 1.0.2 that would fix a flash problem.
Firmware Version 1.0.2 incorporates the following improvement and fix:
Improves the reliability of communication via USB cable when using the Lens Data Registration function within EOS Utility 3 software.
Fixes incorrect indications in the Norwegian menu screens.
It's a shame such a good camera has a problem like thius. Mine was repaired twice and seems to be repaired. Has worked for about four months now. The "Flash cover" is what I was told was the problem. Mine was under warranty and was repaired at no cost.
