The Fujinon YV10X5B-2 is a manual zoom lens for CCTV and other industrial applications. It has a focal length range from 5mm to 50mm (a 10x zoom) that results in very narrow views (around 5°) to medium wide views (about 50°) so you can use it for various jobs or move the camera from location to location. It has a fast f/1.3 maximum aperture so camera can be placed in less than bright environments. The lens can be fitted to cameras with 1/4-inch or 1/3-inch imagers.
Telephoto to Wide Angle
The YV10x5B-2 will provide you with the views you require for your specific CCTV requirements. At full wide angle the lens displays over 51° horizontal angle of view (and 39° vertical) on a 1/3-inch CCD camera. At full zoom on the same camera it produces 5° and 4° respectively. On a 1/4-inch imager (CMOS, CCD, whatever) at full wide you can expect 39 horizontal degrees with 29° vertical. At full zoom you can expect to see 4° and 3° receptively.
Low Light Not A Problem
This lens allows you to place the camera in positions that may not be the most well lighted but tend to be sensitive areas for security and surveillance. With a maximum aperture of f/1.3 the camera can be used in dimly lit areas as well as perfectly lighted positions.
