Don't adapt your Nikon lenses for use on your Cion camera, replace the camera's mount instead with the Nikon to AJA CION replacement Lens Mount from MTF. Services Ltd. Take advantage of the CION's replaceable mount design, and convert your Cion camera from a PL Mount to a Nikon G compatible mount using just four screws. This mount accepts all virtually all Nikon mount lenses, including Nikon G type lenses which do not feature a manual aperture ring on the lens. The replacement lens mount features a mechanical connection for G lenses that allows you to manually control the aperture on a G type lens as if the lens had a manual aperture ring.
The body of the adapter is made from aluminum for its balance between strength & weight, and is anodized for scratch and corrosion resistance. The nickel-plated brass mounting surface mates with your Nikon lenses. The replacement mount is mechanical and works with Nikon mount lenses only and does not contain any optics or electronics.
