he Fujinon YV5x2.7R4B-SA2 is a 5x manual zoom lens with a wide aperture and DC-type auto iris system. Advanced design and engineering along with special optic glass provides superior image quality with IR sensitive day/night cameras and monochrome cameras as well as color units. It has a variable focal length from 2.7 mm to 13.5 mm (a 5x zoom) that results in wide to medium views throughout its zoom range. On a 1/3-inch CCD camera the lens will show an impressively wide 99° horizontal angle of view and at full zoom (13.5 mm) the lens shows 20°. On 1/4-inch CCD cameras the lens shows 74° and 15° respectively.
