KIPON CRF-M4/3 adapter is designed for the Micro Four Thirds camera, allowing Contax Rangefinder RF outer lenses with built-in focus ring to be mounted onto Micro Four Thirds camera bodies.
With KIPON CRF-M4/3 adapter, although the lens will fit physically, automatic diaphragm, auto-focusing, and other functions will not work, only manual model will be available.
