The electric zoom lens is a new type of lens that uses an electric motor, control card and software to control the zoom factor of the lens, and can achieve parfocality by observing the real-time computer screen to obtain the clearest picture. It has an automatic alarm protection function to effectively protect the lens from mechanical failure.
Electric zoom lenses are divided into two-variable lenses and three-variable lenses, which have the characteristics of large zoom factor, fast zoom speed, and easy operation. Among them, the three-variable lens can adjust the focal length, focusing and aperture functions at the same time, and can be manually controlled through the back-end controller.
There are three ways to zoom with an electric zoom lens: turn the "focus ring" to zoom, which can quickly zoom in and out; turn the "zoom/focus control ring" to zoom, and you can control the zoom speed when zooming; use the "electric zoom button" Zoom, the zoom process is more stable and even-speed.
In short, the electric zoom lens is a high-tech, high-precision, high-value-added lens that is widely used in security monitoring, drones, automobile assisted driving and other fields.
