You miss my point, EF lenses are pretty much fixed at this point as no more willAnd no one is adapting RF glass to anything. An RF camera would have an RF mount. An EF camera isn't using RF lenses.
I’m only buying RF from now on but if I want a Cinema camera which I’m considering, I’ve got nowhere to go. I can’t put RF glass on EF mount ever.
I was asking if they make an RF Cinema camera, how adaptable is the mount? Are existing users stuck to adapting EF glass to fit an RF Cinema camera which won’t go down well or can the mount be switched in some way?
