Q: 1. So if I use this adapter with the EF Len's, let's say 50mm 1.2, will I be able to set the ring like RF lens and use It?

A: Yes this adapter would allow to maintain full control of a Canon EF 50mm f/1.2L lens via the control ring.

Q: 2. Does it works with the EF-S Sigma 8-16?

A: According to Sigma, the Canon Control Ring Mount Adapter EF-EOS R will work with the Sigma 8-16mm lens but the camera’s “Scene Intelligent Auto mode” cannot be used. Also the 8-16mm is a crop sensor lens so the camera would need to be a crop sensor model such as the R10,m R50, R7, or if you are using a full frame, the camera would need to be set to crop mode.

Q: 3. Does the control ring mount adapter come with dusk covers for the RF and EF sides? Or are they separately purchased?

A: Yes the adapter comes with the front and rear caps.

Q: 4. Why are you copying Fotodiox?

A: In reality, Fotodiox (a good company I do like, and I do use many of their products) is actually copying Canon. Canon makes the cameras with RF mounts and dictates the correct mechanical and electronic standards for them. Canon makes the RF lenses, EF lenses and EF-S lenses and dictates the correct mechanical, optical and electronic specifications for them. Fotodiox is riding on Canon's coat tails, and is only able to manufacture adapters thate are possibly "Canon comatible" because Canon allows it.

Q: 5. Does this adapter have any sort of interface port build in to it, for example a micro-USB port, so that the ring's firmware can be upgraded if necessary?

A: No, the following unit does not offer any usb ports in order to provide updates.

Q: 6. Will this work with the Canon C70?

Q: 7. I have a Canon EOS 5D Mark IV DSLR Camera, Will this adapter let me use the Canon RF 100mm f/2.8 L Macro IS USM Lens with it?

A: RF-mount lenses do not work on EF-mount camera bodies. The Canon Control Ring Mount Adapter EF-EOS R is meant to use older DSLR lenses on mirrorless camera bodies. Here is an EF-mount 100mm macro lens that would be fully compatible with your Canon 5D Mark IV: https://bhpho.to/3yxMIFh.

Q: 8. It's compatible with D6 Mark II?

A: This will not work on the Canon EOS 6D Mark II. This is to adapt EF mount lenses to work on RF mount cameras. This will only go on RF mount cameras. The Canon EOS 6D Mark II is EF mount. There is no way to adapt RF lenses to EF mount cameras.

Q: 9. Can I use this on a Canon 6D for lenses from a T5?

A: Nope. This is to adapt SLR lenses from Canon (EF-mount) to the RF camera system (EOS RP, R, R6, R5).

Q: 10. When this adapter is used to control aperture, does the camera focus at the set aperture, or wide open?
