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

bnc456 — Tue, 27 Dec 2022 14:25:09 GMT

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!

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.

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

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.

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.

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.

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.

@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.
