EOS 5DS R mount/adapter needed for Rokinon Cine lens

Hello, I have a Canon 5DsR and have recently bought a Rokinon 50mm T1.5 Full Frame Cine DS and need an adapter to fit it to my camera. Can someone point me in the right direction to what mount/adapter I am needing? thanks!

There is no RF-EF adapter. The flange distance (between flange mount and sensor) for RF cameras is shorter than the EF mount. That is why EF lenses are able to be mounted on RF bodies (with the adapter).

Need to return the lens for an EF model (if they have one).

If you bought the RF mount version, you are out of luck. It is impossible to make an adapter to mount an RF lens on an EF camera like your 5DsR. 

Your only options are to exchange the RF lens for an EF lens, or buy a RF mount camera.

Greetings,

That lens comes in a Canon EF mount.  Is this the model you own?  If so, It will attach to the body without an adapter.

Hello, it came with an RF mount already attached to it, so I believe I just need a mount to attach it to my canon camera.

This lens is available in multiple mounts. Which mount do you have?

Thank you all. I bought this from an online auction with limited info on the lens to begin with. So, luckily I'm only out $20. If anyone has any advice on the resale of this lens (have never used ebay and besides Facebook market place) so I can get a new lens compatible with my camera I would love to hear it! Thanks.

Are you sure its an RF mount? The Rokinon website doesn't list an RF mount version? It's an almost $400 lens new. If you got it for $20 is there something wrong with it?

I live in a small town where two men buy and sell items from amazon pallets for cheap on an online auction page. We have received many good deals from the amazon pallets such as a DJI Mavick Mini in great condition under $20, as well. The lens looks brand new in a damaged box, but I couldn't be certain anything is wrong with it without attaching it, of course. I have attached the link to the amazon item # listed on the box. Maybe that will give additional information that will be of help.
