Description
Lenses in the varifocal category offer a selection of imager format optics in various focal length ranges. The CS lenses require fewer glass elements to focus
at a shorter distance, while not affecting picture quality. Lenses are available in CS-type mounts.
All varifocal lenses feature high resolution power in a compact body.
The VA Series lens has a manual iris, manual focus, and manual zoom. The VD Series lens has a direct drive auto iris, manual focus, and manual zoom. The
VD Series has an industry-standard, square, 4-pin connector that plugs directly into the camera receptacle. In addition, all auto iris lenses include a spot
filter.

Installation
1. Remove the dust cover from the lens.
2. Remove any dust with a soft brush or clean compressed air.
3. Install the lens by carefully threading it clockwise on the mount of the camera until it is fully seated.
a. If the lens has a coupling ring, tighten it against the camera. Use a C/CS-mount adapter if attaching a C-type lens to a CS-type camera.
b. If your lens has a direct drive or video drive auto iris, plug the electrical connector directly into the camera’s DC-drive or video drive socket,
whichever applies.
4. Follow the camera operating instructions for iris and focus adjustments.
