Fujinon FU-288AVF 2.8-8mm Auto Iris Vari-focal Surveillance Accessory

Wide-to-standard vari-focal lens for CS-mount

This Fujinon FU-288AVF lens covers a 2.8 mm to 8.0 mm focal range on 1/3-inch format colour cameras. The CS-mount design fits compatible surveillance housings, while the DC auto-iris adjusts exposure automatically as lighting changes. Installers gain a single optic that spans wide-angle to standard views without swapping hardware.

Covers 99° 52' to 35° 14' horizontal field angles

At the wide end the lens delivers a 99° 52' horizontal angle, narrowing to 35° 14' at telephoto; vertical coverage shifts from 73° 17' to 26° 24'. Focus operates from 0.3 m to infinity, so nearby objects and distant scenes stay sharp. The F0.95 maximum aperture gathers ample light, though the iris can stop down to the equivalent of F360 when scenes are very bright.

Approximate 50 g mass keeps mounting loads light

The compact barrel weighs roughly 50 g, adding minimal stress to camera brackets or pan-tilt units. Passive cooling is sufficient because the lens contains no active electronics beyond the tiny iris motor. Power draw is limited to the low-current DC iris signal supplied by the camera, so no separate supply or heat management is required.
