Description
Lens format F9 mm (1/1.8 inch). The presented lens is a varifocal type, which means you can independently set the required focal length. The focus value, depending on the observation requirements, can be set in the range from 3.8 mm to 16 mm. When the focal length changes, the viewing angle of the lens also changes. With a 1/1.8-inch matrix, the viewing angle will be 103.1° ~ 2.8°, and with a 1/2-inch matrix - 100° ~ 2.7° horizontally. Do not forget that the amount of objects that will fall into the lens depends on the focus distance.
