Will this adapter electronically close the aperture of Mamiya 645 AF lenses? I.e. for the newer lenses without an aperture ring- If I shoot with my Schneider 150 LS at F/16, will the sony body close the lens to F/16, or can I only shoot it wide open?

You would need this version for a 645AF lens: https://bhpho.to/3xc5L1J This adapter does not support electronic communication between an attached camera and lens. To control the amount of light that enters a Sony E-mount camera when using this adapter and a Mamiya 645 AF/AFD lens, an aperture-control ring is built into the adapter which couples with the lens's aperture mechanism so that adjustments to brightness as well as depth-of-field can be made.
