The AC-789 kit includes a higher bayonet to hold a MFT-mount Body and mounts to the Actus view camera.

This higher bayonet is needed to mount MFT-mount bodies like the Olympus OMD series.

NOTE: this bayonet results in 4mm more distance between the lens and the MFT-body, so that the use of certain combinations with SLR-lenses may be restricted.
