Question about Manfrotto MA 015 Adapter 3/8" to 1/4
does this adapter fit the Canon EOS 80D ?
Yes as 1/4 is standard but it's not a great idea as the camera will not be stable on such a little piece of metal. You should better get a plate and then put the plate on what you want.
Yes, the thread is standard on all current cameras.
