Q: 7. will this allow me to change f stops on the lens?

A: No, it will not. As stated under the Overview, electronic communication between an attached camera and lens is not supported by this adapter. When removed from a compatible Canon camera, the aperture diaphragm on a Canon EF or EF-S mount lens is designed to open to its widest setting. A Canon EF or EF-S mount lens may be effectively used with its aperture diaphragm fully open along with the Vizelex Pro ND Throttle Lens Mount Adapter. Otherwise, an aperture value on a Canon EF or EF-S mount lens may be set by first placing the lens on a Canon EOS camera and then pressing the camera's depth of field preview button while removing the lens prior to placing it on the adapter. But the adapter does not directly offer aperture adjustment control.
