Q: 1. Will the RF 2x extender be compatible with the new RF 200-800mm lens?

A: Yes, the Canon RF 2x extender is compatible with the Canon RF 200-800mm lens.

Q: 2. Does either one of the two 2x TC config work? 1] R5 -2x (rf) - RF/EF adapter - 100/400 II (ef) 2] R5-RF/EF Adapter-2x TC (EF) - 100/400 II(EF)

A: The EF-to-RF adapter doesn't properly mount to the RF-teleconverters due to the optical tube. You'll need to use option 2.

Q: 3. Have anyone tried this RF extender on a RF body, then an EF adapter, finally, an EF lense? In theory, it should work...

A: No, they are not compatible. All Canon RF to EF adapters have a narrow square shape opening on the back; therefore, the Canon Extender RF 2x front optic cannot fit through the adapter.

Q: 4. Will the auto-focus on the R5 work with RF Extender 2X and RF 100-500 lens?

A: Yes, autofocus is available when using the RF Extender 2X with the RF 100-500mm lens while mounted on the EOS R5.

Q: 5. Does this extender does the glass on Canon's RF 100-500 when zoomed out to 300mm?

A: While I do not quite understand the question due to the way it is worded, when using the Canon Extender RF 2x, the Canon RF 100-500mm f/4.5-7.1L IS USM Lens can only be operated within the 300-500mm focal length range. Before attaching the 2x Extender, use the lens' zoom ring to set the focusing distance between 300mm and 500mm, then attach the extender to the lens. The lens may then be attached to the camera. Attaching the extender forcibly with the focusing distance set between 100mm to 300mm may result in malfunctions or other damage.

Q: 9. It's not compatible with a 70-200 or the RF 24-105, due to physical incompatibility, can it be resolved by using extension tubes like Kenko or JJC? It's not specifically recommended by canon but These extensions tubes are usually used for Macro. Some setup has been made combining the canon extender (EF) 2x and 1.4x with an extension tube ( to shot the moon for exemple). So the question is woukd it work?

A: No , it will not work
