Is there an adapter to use RF lenses on the EF mount?

[Norm5353]

I have a E2000D with ef mount.  I was given a 70-200mm lens in very good condition however it is an r mount from a newer camera.  Is there an ef to r mount adapter and if so any pointers on which to get.

Currently there are no adapters to use RF lenses on EF bodies.

I would suggest looking into the EOS R series camera lineup. It is physically not possible to adapt an RF Mount lens on an EF Mount camera. RF Mount lenses sit closer to the image sensor than an EF Mount lens would. This isn't physically possible.

There is no adapter, and no adapter is possible -- the RF lens needs to be closer to the sensor than the mount on the front of your EF-S camera.  This is impossible.  (This is "flange focal distance".)  Shame, because that's a nice lens.  But if you want to use it, you'll need a new camera -- this might cost less than the lens, so it could be a good choice.

If you want to know more about lens compatibility, I wrote an article about it:
