Unfortunately, I don't think you can adapt Canon or Nikon lenses to the CY mount.

If you want a focal reducer for the cine lenses, your best bet is to get a EF to MFT model as that will allow you to use your CY lenses with an adapter, along with Nikon F/G and other mounts.

My only issue with EF adapters is that you'll want to get an electronic one that can operate the aperture as virtually all of them do not have a mechanical iris.

(I'm not a fan of electronic lenses, they tend to be prohibitively expensive to service so I prefer PL or Nikon F/G. Not that matters with the DS lenses as they're fully manual.)

That's the reason I have the Metabones Speedbooster XL in Nikon mount. Like, I have a bunch of Nikkor glass and Sigma, Tokina etc are all Nikon mount as well. Allows for easy dummy control with a mechanical ring for the aperture. That means the SB itself is a bit cheaper. Also that alternatively, you can use it without a focal reducer, just with a simple and affordable adapter.

But I agree on EF, as a taking mount, it's more flexible though. So for my Contax Zeiss (C/Y) and Leica Summicron-R (L/R) I have the ZY Optics/Zhong Yi/Mitakon Lens Turbo II in EF mount (to m4/3). I then use a simple C/Y or L/R to EOS/EF adapter from K&F (Kent & Faith) Concept.

so basically i would need new metabons speedboster mft to canon. Just to understand i cant use cy metabons speedboster with canon adapter at front to attach  canon Rokinon

 

Thanks guys

Correct. You can mount C/Y lens to EF taking, but not EF lens to CY taking.
