Specially made for remote control applications, the Fujinon 8.5-170mm f/1.8-2.7 eXceed 2/3" Teleconference Bayonet Lens is from their videoconferencing series. Fujinon designed this lens with a a versatile, 20x zoom range covering focal length range of 8.5mm at the wide end all the way to 170mm at the telephoto end. The wide 8.5mm focal length allows you to keep multiple subjects in the frame while the 170mm focal length allows for focusing on a single subject. The zoom, focus, and iris controls are accessible via separately available analog remote control.

The lens's internal focusing mechanism maintains a constant lens length when focusing or zooming, keeping the balance of the lens consistent. This consistency is an important consideration when mounting this lens on electronic pan / tilt devices. Fujinon designed this lens to be lightweight at 3.4 pounds, preventing unnecessary wear on the motors used for camera movement. These features are useful for teleconferencing, security, or other applications requiring lens remote control.
