Here is how it works,

You have a few lenses from a single or multiple  mount, IE: M42, Nikon, Canon FD, Leica Thread, Leica M, C-Mount, Olympus OM etc...

OK, Now take nice photo on your m4/3 with each lens in the same mount and then post a topic in the "Lens Sample Archive", and I will make it a sticky... One I have a quite a few,  I will make a Lens/Camera Combo Image Index similar to the Lens Archive Index.

The mount is important, not what camera is made for.
