Abstract
(EN)
An interchangeable lens unit (2) is provided with: a plurality of focusing lens groups (G2, G4, G5), a plurality of focusing actuators (63, 64, 65), and a drive control section (45). The focusing lens groups (G2, G4, G5) have an optical axis (AZ), and an object distance is changed by moving the focusing lens groups in the Z-axis direction, which is parallel to the optical axis (AZ). The focusing actuators (63, 64, 65) drive the focusing lens groups (G2, G4, G5), respectively. The drive control section (45) controls at least one focusing actuator (65) among the focusing actuators (63, 64, 65) such that only the focusing lens group (G5) among the focusing lens groups (G2, G4, G5) reciprocate in the optical axis direction when a wobbling operation is performed.

Une unité d'objectif interchangeable (2) selon l'invention est munie : d'une pluralité de groupes de lentilles de focalisation (G2, G4, G5), d'une pluralité d'actionneurs de focalisation (63, 64, 65) et d'une section d'entraînement (45). Les groupes de lentilles de focalisation (G2, G4, G5) ont un axe optique (AZ), et une distance d'objet est modifiée en déplaçant les groupes de lentilles de focalisation dans la direction de l'axe Z, qui est parallèle à l'axe optique (AZ). Les actionneurs de focalisation (63, 64, 65) entraînent respectivement les groupes de lentilles de focalisation (G2, G4, G5). La section d'entraînement (45) commande au moins un actionneur de focalisation (65) parmi les actionneurs de focalisation (63, 64, 65) de telle sorte que seul le groupe de lentilles de focalisation (G5) parmi les groupes de lentilles de focalisation (G2, G4, G5) effectue un va-et-vient dans la direction de l'axe optique lorsqu'une opération d'oscillation est effectuée.
