MOUNTING AND CONNECTING

For PL mount, read the following instructions before mounting the lens.

2. Do not mount the lens if the camera is set to a mount communication mode other than "/i". Doing so

could result in malfunction.

A variety of professional camera accessories are available using φ 15 mm and φ 19 mm rod adaptors.

(When using a φ 19 mm rod, attach the supplied attachment holder to the lens holder.)

Note

1. Before mounting the lens on the camera, make sure that the power of camera and the power of supply

equipment are turned off.

2. Be sure to use the lens holder when mounting the lens on a camera. Be sure to avoid applying

excessive weight to the lens mount when the lens is mounted on a lens support.

1. Attach the lens to the camera tightly so that both mounting surfaces are

in complete contact.

Note

For details on how to attach the lens, refer to the camera's

operation manual as well.

2. Secure the attachment holder on the lens support using

the clamping screw supplied with the lens support.

3. Fix the lens support to the rods using lens support fixing screws.
