Thankyou , let me know if you are having issues as I own both lenses and can measure them if required Samyang lens front ring inside size 75.12mm and back ring is 69,66mm inside diameter (back 5mm of inside ring is 69.66mm then the rest is 75mm inside diameter) total thickness of rings is 12mm. Mounting holes like in your design for mini guidescope and asiair and eaf would be great.

I love it. I am not seeing the wire holders like you show around the ASIAir Plus device though. Did those get forgotten?

I did not design these, but simply search for "asi air cable holder"

Is it possible to rotate the lens while it is installed with the EAF?
