The zoom and focus ring does not turn smoothly or at all when the camera is mounted to a tripod.

Depending on the size of the mounting shoe (mounting plate) for the tripod, the mounting shoe may interfere with the zoom and focus ring on the lens. If the mounting shoe is made of soft material such as rubber or cork, tightening the screw of the mounting shoe too much may make it difficult to turn the zoom and focus rings.

Try the following to resolve this issue:

1. Slightly loosen the mounting shoe screw to reduce the pressure between the shoe and the camera. Then turn the camera left or right to change the angle at which it is positioned on the mounting shoe.

   IMPORTANT: Do not loosen the screw too much to prevent from accidentally dropping the camera.

2. In order to prevent the camera mounting shoe from interfering with the movement of the ring, attach the camera using a commercially available tripod adaptor or quick shoe, etc.
