Having gone through the same issue with the Extreme updated improved nikon mount, I have found that you need to place a small screwdriver in between the pressure points and expand the mount. looking at the opening at an angle you can see a small space in three palces around the opening to expand. Its touchy, too much and you need vice grips to put a lens on, too loose and well you get the point. They should have used the wavy washer method which not likely a patent issue as many tape machines used the same principal to apply spring like pressure.

I have not seen the nikon ultimate mount.
