With manual close-up photography using the copy stand in any situation or with the lens pointing down , if you turn the clamp screw to the ON position, rotation of the focusing ring becomes tight. This helps to prevent the rotation of the focusing ring due to the lens's own weight and avoid any shift in focus. · When shooting in the autofocus mode, turn the clamp screw to the OFF position. Activating the autofocus mode while the clamp screw is in the ON position slows down the focusing speed. CLAMP ON OF F 25 Tripod Mount FA 200mm f/4 ED (IF) is equipped with the tripod mount.
