Anyone has experience with stiff PK11 aperture coupling lever?
D7000 seems like having problem to flip the aperture for depth-of-field preview... the motor is not having enough torque to move it.
I tried to flip it with my finger when my lens is mounted on the ring and felt stiff too.
On its on, the lever on PK11 is ok to move by finger. Any experience sharing is welcomed.

See page 270 of your users manual. You should be using a PK-11A since the camera is an AI camera. There are no electrical contacts for the chipped lens, so there is no power for the SW motor.
The Kenko digital extension tube are designed to include all electric controls.
