There is almost no commonality between different camera makers regarding lens mount systems. Each manufacturer has developed their own system, and build camera bodies and lenses that only work with their own lens mount, with the Four Thirds System being a partial exception. This was different before 1970 when most of the manufacturers use either M42 or M39 lenses, most of which can still be used depending on the particular adapter you can find.
This does not necessarily mean that one is limited to only mounting, for example, Pentax lenses on a Pentax camera body. There are independent optics companies that make lenses for the various otherwise proprietary mount systems, thus providing alternative sources for lenses that are often of equal quality and/or less expensive than the camera maker's own lenses. Another possibility is the use of adaptors that allow mounting a lens for one system on a camera with a different lens mount. However, the use of an adaptor usually results in reduced functionality, typically requiring the manual setting of aperture and focus, or perhaps not being able to use any aperture other than "wide open".

Famous quotes containing the word mounts:
“And now he comes again with clatter of stone,
And mounts the wall again with whited eyes
And all his tail that isnt hair up straight.”
—Robert Frost (18741963)
