Abstract
A camera can include a camera body and a lens mounted to the camera body. Light passing through the lens can be incident on a recording surface that is adapted to capture the incident light. The camera can include a focus calibration control, wherein manipulation of the focus calibration control causes the focus calibration control to adjust a distance between the lens and the recording surface. The camera can include a locking control that is separate from the focus calibration control. The locking control can be configured for selective engagement to prevent the focus calibration control from adjusting the distance between the lens and the recording surface.
