The button and metal face plate for the mode dial on my Canon 5DMkIII are missing. I lost them last December while running through the jungle, trying to keep up with a troop of chimpanzees. The dial itself is still intact and I've been able to change the mode by pressing a small pin into the button hole to unlock the dial.
I have a complete replacement dial/button/face plate in hand. Does anyone know how complicated it is to change this out or where I might find detailed instructions. . . . . .or at this point, should I just send it in to a professional for repairs (I have replaced components on a number of other cameras, with good success).
Thanks!
