I have a problem with a Nikon PC 85mm lens. When I attach it to the Nikon S-M adapter then it sort of sticks and the whole turns very stiff. The adapter on itself is buttery smooth of course; also the lens turns rather easily. The combo fails.
The bayonet engages correctly. [So it is not like the video a few posts back]. It can be put on and off with relative ease. There is no play.
Having looked at it, it looks as if the lens lips or flanges that stick out in the back touch the inside of the adapter, and this way forces the two sides of the helix out of each other.
I tried it on a C-M adapter and there this sticking is was there too, albeit heavier, because I could feel the spring in the lens starting its action and it was hard to reach both sides of the distance scale.
Is this known? How to remedy?
