I bought a new outfit in May, including an 80D, a 1.4TC, and 400mm II. I have been using it quite a bit, and never saw any problems until the other day.
I turned it on, and was trying to set the ISO and nothing was happening. Same for trying to set the drive, etc. When I looked through the viewfinder, it was black. I could not for the life of me think of what was going on.
In trying to debug it, I did notice one thing. When I re-seated the entire lens + TC at the body interface, everything started working.
I need to do more testing to see if this happens again, but I wanted to ask if anyone ever heard of such behavior, and what it might mean.
Thanks,
Mitch
