Related Questions and Answers

Q: 1. What is the blue ring for?

A: The blue ring allows you to adjust the aperture in the lens from wide open to closed down.

Q: 2. Why is the blue aperture ring even necessary when you can adjust the aperture directly on the FD lens?

A: Some FD lenses do not have a manual aperture ring you can turn on the lens with your hand. For those lenses you would use the blue aperture ring in the adapter.

Q: 3. EOS R3 in crop mode with a canon FD 150-600 5.6. The lens is in effect a 240-960 5.6. with booster am at 170-680/F4?

A: The 150-600 less would become 170-681mm and the aperture would open up about 1 stop effectively. However, I am quite sure there is no 150-600mm FD mount lens. Chances are you have a Tamron or Sigma 150-600 lens with an EF mount (auto focus lens). If that is the case you would need this EF to RF booster instead: https://bhpho.to/2LkrTkJ

A: Yes, FotodioX Canon FD Lens to Canon RF-Mount Camera Pro Lens Adapter is compatible with Canon EOS C70 Cinema Camera (RF Mount). This adapter allow you to connect Canon analog FD lenses on Canon RF camera bodies and control the lens aperture.

Q: 6. Is this focal reducer compatible with the RED Komodo X? (No protrusions that might scratch the sensor!)

A: Yes, the Metabones Canon FD / FL to Canon RF Mount Speed Booster ULTRA 0.71x (EOS-R) is compatible with the RED Komodo-X.

Q: 7. Anyone used this on a BMPCC 6K or BMPC 4k?

A: This would work on a BMPCC6K, but the BMPCC4K requires an additional EF-MFT (or speedbooster variant) adapter because of its MFT lens mount. Overall functionality on the BMPCC4K may vary further if the Vello adapter's optics interferes with aforementioned secondary adapter.

Q: 8. Are there optics in this adapter?

A: No, there are no optics in this adapter.

Q: 9. Can I use this with the new Canon r7 and still use RF lenses

A: The Metabones Canon FD / FL to Canon RF Mount Speed Booster ULTRA 0.71x (EOS-R) is compatible with the Canon Eos R7 camera but it can only use Canon FD mount lenses (older manual focus mount). Currently there are no speed boosters for mounting RF lenses to an RF camera.
