Just to be really clear, this will allow me to use an RF mount lens on an EF mount body? It says compatible with Jupiter lenses, but they are PL or EF, not RF.
This is a Canon EF Lens adaptor to Canon RF Cameras & is not limited to Jupiter lenses. As noted above: This is a manual lens adapter and does not provide any electronic communication between the lens and camera body.

how to you adjust the physical iris with this?
The Sirui Jupiter EF-RF Adapter for Canon EF Lenses to Canon RF Cameras is a manual lens adapter and does not provide any electronic communications between the lens and camera body. A lens with manual focus and aperture control rings is recommended, such as the Venus Optics Laowa 15mm f/4 Macro Lens for Canon EF (B&H # VE1540C). This will allow for physical adjustment to the iris while using the lens adapter.
