Heck, the manufacturers don't agree either.
Depending upon the manufacturer the metal part that screws into the camera is either the bayonet mount, the bayonet, the lens mount, or the camera mount. Calling it the camera mount would have been the worst choice, I think. Since Sony calls it the lens mount, I knew that had to be wrong because they don't know doodly about lenses So I went with bayonet.
The 4 screws that hold the metal thingie on the back of the lens go into the next part which is either the lens mount, mount ring, internal mount, internal barrel, or fixed ring; except for the ones, like the Tamron where it is an integral part of the rear barrel. Since the Olympus-broken-zoom freak out's where calling it the mount, I went with that. (In the Canon 35 f/1.4 it's a fixed ring, which I like because then I can tell Aaron we need to fix the fixed ring.)
In retrospect, I should have gone with Paul's choice. Except someone would say that the bayonet mount mount is a camera.
Of course, the thing on the front of the camera where you put the bayonet mount is metal. But guess what the 4 screws that hold it to the camera go into? Often it's metal . . . Oh my. I think I'm gonna have to write another article.
