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

[bnc456]

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).

The description needs to say DSX. Your original post said DS. 

Put it on eBay and start at $300.  You could always relist at a lower price if it doesn’t sell.

I apologize for the confusion. Thanks for your help!

@bnc456,

***EDIT - Seems there were other replies before I posted mine.

The DS version of this lens does not come in an RF mount.  The DSX does.  Your 5Dsr has an EF lens mount. John and Mike have both pointed out an RF lens cannot be adapted to an EF mount  camera. We are only able to offer advice regarding compatibility with your existing device.  Unfortunately, Its not in this case.  New this lens is $450. While the 5Dsr is not known for its video capability 1080/30p, its 50MP sensor and proven 61 point auto focus system was one of the best available for its time.  Still a great camera.  If you are exploring video, consider a newer mirrorless R camera.  You'll have a great video centric lens to start with.
