Expert Answer
Focus ring in a camera helps in focussing the camera manually if desired. The focus ring is provided to adjust the distance between the lens and the film until a clear image of the object is obtained. This ring on the lens body can be rotated and it moves the elements inside the lens so that the image produced by the lens can be brought into clear focus.
