I tried opening the internal flash on my Canon 60D camera the other day and it didn't open at all. I couldn't understand why. After messing around in the menus, I found out that the camera thinks that an external flash is attached. It gives the message "This menu cannot be displayed. External flash is attached."
How do I fix this?
Providing a few photos to explain what happens here. Sorry for the low quality, obviously I couldn't use my 60D to shoot photos of my 60D :))
