Canon R lens mount

The Canon R lens mount is a physical standard for connecting a camera lens to a 35mm single-lens reflex camera body. It was introduced in March 1959 along with the Canon Canonflex.

The R mount was used on Canon's first single lens reflex (SLR) camera. The mount employed a "breech lock" system to attach the lens to the camera body.[1]

The R mount was discontinued in 1964 and replaced with the Canon FL lens mount.[2] Many mirrorless interchangeable-lens cameras are able to use Canon R lenses via an adapter. The mechanism for controlling the aperture is different from both the later FL and FD mount, although they physically still can mate with most adapters.

gollark: I control the bot. Of course I'll know.
gollark: Where is *that*?
gollark: You can't really get 3090s because Nvidia does not allow them to be used in datacentres. Apparently "vast.ai" has them (they run them not in datacentres or something) although I have never tried them for anything. I'm pretty sure there are various model hosting providers available.
gollark: The Ubuntu IRC stuff is formatted as `<person> message` so you probably have to format it like that.
