Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your camera question.

Expert:  Russell H. replied 5 months ago.

I advise you to first of all try setting ETTL II on the Canon EOS 5D. That is almost certainly basically necessary.

The 5D Mk IV is not specifically listed as compatible with this flash model, though the Canon 5D Mark II is listed as compatible.

Try reading this page also, which may have some matter useful to the problem:

And let me know what error code/message/logo, or what symptoms, indicate the flash is not working with the Canon 5D, and I will suggest further measures to try.
