Q: 1. 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?

A: 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.

Q: 2. will this work with canon 5d mark 3? And will this work with Mamiya 645 AF lenses?

A: I use it to attach my Mamiya 645 lenses to my Canon 6D, the baby-brother of the 5DM3, and it works fine. It's not as perfect as having it hooked up to your Mamiya, but it never will be. But you will unlock the greatness of a medium-frame format lens onto a full-frame 35mm equal and the results are like nothing you can get from a Canon lens. I'm not saying superior, but in many ways, they're up there with the traditional L lenses, and if you bought the Mamiya lenses used, you probably didn't spend the L prices. Good luck.
