Q: Will this lens mount adapter work with a Canon 6D Mark II? If not what lens mount adapter will?
A: No, this if for Canon R series only (mirrorless), they sell adapters for DSLR cameras that will allow you to use lenses from other brands but none of the adapters that you will find will allow you to use RF lenses on a DSLR camera.
A: Yeah it definitely is worth it if you shoot manual or a custom setting often. I have one custom setting that uses the ring for ISO and another that uses it for the shutter speed depending on how dim or bright the lighting is. Although you have to own enough EF Canon lenses to justify it, RF lenses have their own control ring built into the lens body out at the end of the lens. Good luck, also I think this might have an ND filter option although I haven't used it, I'm not certain. Ryan
