Power focus is a camera focusing system that adjusts the lens automatically using an electric motor when a button or lever on the camera body is pressed. Unlike manual focusing, power focus allows the photographer to achieve accurate focus quickly and with minimal effort, which is particularly useful for moving subjects or in low-light conditions.
This technology is commonly found in both still and video cameras, enhancing convenience and precision. By automating lens movement, power focus improves workflow efficiency and ensures sharper images, making it a valuable feature for both amateur and professional photographers.
