PROBLEM TO BE SOLVED: To provide a camera system capable of achieving optimal driving control of a focus lens per mode of ONE-SHOT and AI-SERVO.SOLUTION: A camera system formed by a lens for forming the image of a subject being attached to a camera comprises: a communication unit that communicates a driving amount of a focus lens which adjusts a focal position of the lens to the lens; a determination unit that determines whether or not a target position where a focus is going to be brought is changing in time series; and a control unit that performs driving control of the focus lens by giving priority to accuracy in a stop position of the focus lens if the target position is not changing in time series, and performs driving control of the focus lens by giving priority to driving speed of the focus lens if the target position is changing in time series. 【課題】ＯＮＥ−ＳＨＯＴやＡＩ−ＳＥＲＶＯのモードごとに最適なフォーカスレンズの駆動制御を実現できるカメラシステムを提供する。【解決手段】被写体像を結像させるレンズがカメラに装着されて構成されるカメラシステムであって、レンズに対して、レンズが有する焦点位置を調節するフォーカスレンズの駆動量を通信する通信部と、焦点を合わせようとする目標位置が時系列的に変化しているか否かを判定する判定部と、目標位置が時系列的に変化していない場合には、フォーカスレンズの停止位置の精度を優先してフォーカスレンズを駆動制御し、目標位置が時系列的に変化している場合には、フォーカスレンズの駆動速度を優先してフォーカスレンズを駆動制御する制御部とを備える。【選択図】 図１
