Abstract
A focus control device is adapted to adjust a camera lens. The device comprises a rotational input device (), a variable gear ratio means () and a rotational output means so coupled to communicate a first rotational movement applied to said rotational input device to said variable gear ratio means () and to communicate a second rotational movement from said variable gear ratio means () to said rotational output means. The variable gear ratio means provides a variable adjustment of the angular velocity of said second rotational movement relative to the angular velocity of said first rotational movement.
