A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis. Lenses are made from materials such as glass or plastic and are ground and polished or molded to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing.
Fixed focus lens
Auto iris or Manual Iris
The lenses of Reolink cameras are mainly divided into a fixed focus lens and a zoom lens. The zoom lens can adjust the focal length within a certain range, but the focus lens can't. So the zoom lens is more convenient, especially when there are some places where it can't move forward or backward.
Please check the Reolink cameras that have a zoom lens.
