MOUNTING AND CONNECTING
For PL mount, read the following instructions before mounting the lens.
1. The PL mount supports Cookeʼs /i Technology, so make sure that the camera is set to "/i".
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 Φ15 mm and Φ19 mm rod adaptors.
(When using a Φ19 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. Push the lens toward the camera until both mounting surfaces are in
complete contact and clamp the lens support to the rods.
