HOW TO ASSEMBLE LENS AND CS MOUNT CAMERA

Turn the lens clockwise to lock onto camera part mount screw.

 

(When the lens locks successfully, it can turn around SLIP state)

Turn clockwise until stop by stopper even if it almost SLIP state. 

 From that point, turn the lens counter clockwise to rotate it in the SLIP state by 
up to 340 degrees. In such a way, you can adjust the lens to a desired position.
The proper installation is that you face each flat (non-hood) side toward the corner.

Connect the lens cable to the appropriate camera connector.

 Finally, use the focus lever and zoom lever to fit the zoom factor and focus. 

Then, fix the lens with the camera.
