Abstract

A method and apparatus for adjusting the focus of a camera. A rotatable focus member, when rotated, effects movement of an indicator element. The position of the indicator element is sensed by a sensing element and is passed to a controller within the camera. The controller prompts a motor to drive a focusing element of the camera in response to changes in the sensed position of the indicator element. The focus member effects movement of the indicator element by way of rolling resistance as opposed to sliding friction, allowing for more consistent and controlled manipulation.
