These Motorized Zoom Lenses are compact, rugged, 1/3-inch and 1/2-inch image format auto iris lenses. Their high sensitivity and reliability provide optimal performance in all environments.

The 1/3-inch DC-iris Series Lenses have been designed for more economical uses and are provided with a standard CS mount for use with a wide variety of cameras.

The 1/2-inch Video-iris Series are high quality lenses, and are provided with both CS and C mount options.


For the auto iris control, all lenses use the standard 4-pin EIAJ connector which fits directly into the camera’s iris output. For zoom, focus, and pre-position control, the lenses are fitted with an 8-pin DIN connector.

Impressive optical quality is a result of combined high standards for resolution, contrast reproduction, and lens coating. The lenses have been designed to match with the complete range of Bosch cameras. When used in combination with the 1/2-inch Series cameras they provide the necessary large F/stop and high quality camera optic features.

Lenses in this series include 10x, 15x, and 20x zoom range models. Some models provide optional preposition and manual iris override functions.

The mechanical construction has been designed to withstand the frequent control operations of the iris, zoom, and focus operations. For a cost effective lens that provides the high quality and reliability needed to enhance camera images, these lenses are the ideal solution.
