CH3580 is a C mount fisheye lens created to support 2/3’’ or smaller size image sensors. The type of fisheye effect actually achievable depends on your camera sensor size. When used with a 2/3’’ CCD sensor, it will produce a full frame fisheye image with 11mm image height. A full frame fisheye lens, also known as diagonal fisheye lens, is capable of capturing 180 degrees field of view along its diagonal. Even though they are not capable of capturing super wide angles, they are widely used because the image produced by this lens is rectangular and will not have black edges.The front part of the lens is multi-coated to cut down flaring and ghosting. In addition to the lens, you will get a removable lens hood, meant to reduce glare and protect the lens. This lens is excellent for applications such as security&surveillance, industrial inspection, etc.
