To provide a focus adjustment support device that supports a focus adjustment independent on visual information.SOLUTION: A focus demand 4 comprises: at least two oscillation motors 41 that notify a photographer of the fact that a current focus position is on the near side or the depth side by oscillation; and a control part 42 that is previously set so that the oscillation focus ranges making each oscillation motor 41 oscillate are partially overlapped, and makes one or more of the oscillation motors 41 corresponding to an oscillation focus range containing the current focus position of a lens 3 oscillate.SELECTED DRAWING: Figure 3 【課題】視覚情報によらずにフォーカス調整を支援するフォーカス調整支援装置を提供する。【解決手段】フォーカスデマンド４は、現フォーカス位置が手前側又は奥側であることを振動によりカメラマンに伝える少なくとも２個の振動モータ４１と、各振動モータ４１を振動させる振動フォーカス範囲の一部が重複するように予め設定され、レンズ３の現フォーカス位置を含んでいる振動フォーカス範囲に対応した振動モータ４１を１個以上振動させる制御部４２と、を備える。【選択図】図３
