摘要： A lens-barrel and a camera system including the lens-barrel are in an automatic focus mode in which a focusing unit is automatically driven by an automatic focus unit, during a time when a manual operation member is not operated. When the manual operation member is operated in a second direction, switching is done to a manual focus mode achieving focus by operation of the manual operation member in the second direction. However, when detecting the operation of the manual operation member in the second direction during a zoom operation in which the manual operation member is being operated in a first direction, switching is done to the automatic focus mode without being switched to the manual focus mode. Therefore, unintentional switching from the automatic focus mode to the manual focus mode during the zoom operation can be reliably prevented.
