SLR Magic Anamorphot-CINE lens 2x 50mm T2.8 (MFT)

[threedi]

I see that the SLR Magic 2x 50mm Cine Anamorphot delivers a Image Circle thats S35 (same for the 70mm also) would it therefore be possible to mount this (with a converter) to an A7 R2 run in S35 crop mode and get 50mm from it?  I also dont understand that if the 35mm MFT mount version is delivering an Image Circle of MFT is it then a true 35mm lens on say a GH4 or would it turn into a 70mm. If the image circle is MFT then there isn't any cropping, is there? I guess if the 50mm and 70mm deliver image circles of S35 then there will be cropping on the GH4 but the 35mm seems to deliver a native image circle onto the sensor, or am I completely wrong. Please help.

I get that the 16:9 aspect ratio on the A7 will create a mega wide image with a 2X and Im after that sort of effect btw.
