Many CCTV applications are in need of a lens that can be quickly switched from capturing a broad view of an area to zooming in for a close-up look of distant objects when necessary. A few good examples include coast guard monitoring, highway traffic surveillance and border crossing security. The Tokina TM33Z1523AI is specifically designed for these purposes. Through the use of a compatible CCTV lens controller device, the focal length on this lens can be changed from a wide view of 15mm to a telephoto view of 500mm, which translates into a 33x optical magnification. And with a name like Tokina, you can expect to get only the best, both in terms of image quality and lens durability.

An auto iris function will permit the use of the lens in areas where light intensity changes over the course of a monitoring period.
