Hi all, I am new here. I got a Canon 5D Mark IV. Today, I try to use my Flash, as soon as I plug my Flash into the Camera body, I get "FEL" and I got a Lightning Bolt with a star on the corner. And it lock out my camera, I can't get it off. Can someone help me? Many Thanks. I try restting my camera setting, it won't help.
Is my Flash malfunctioning? Please see attach picture.
Thanks, after searching for hours, I found my M-Fn button stuck pushed in! I never use that button! I have to try to pick that button back out and then exercies the button in and out couple times... now I free the button, but still sticky... I just have to disable the button I guess. I hardly use it.
