What is an AF Mount Lens?

An AF mount lens is a type of lens designed for use with cameras that feature an autofocus (AF) system. The “AF” in AF mount lens refers to the lens’s ability to communicate with the camera’s autofocus system, allowing for quick and accurate focusing. AF mount lenses are designed to work seamlessly with cameras that feature an AF system, providing fast and precise focusing, even in low-light conditions.

How Does an AF Mount Lens Work?

AF mount lenses work by using a combination of electrical and mechanical components to communicate with the camera’s autofocus system.
