35mm rokinon f/1.4 on manual cameras?
The only thing they're missing is the aperture connector metal thing that AI-S lenses have for certain older camera bodies (I forget what it's called).
The metal fork that connect to pre-AIS camera's. Nikon FM2 do have a takeaway ring for taking over the aperture position of the aperture ring. The nodge on this ring has a hinge and can be fold up to connect to more old pre-AIS lenses.
