| Zusammenfassung: | A focus control device is adapted to adjust a camera lens. The device comprises a rotational input device (1), a variable gear ratio means (10) 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 (10) and to communicate a second rotational movement from said variable gear ratio means (10) 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. |
