Title (EN) ZOOM LENS SYSTEM AND IMAGING OPTICAL DEVICE WITH THE SAME
(FR) SYSTÈME D'OBJECTIF À FOCALE VARIABLE ET DISPOSITIF OPTIQUE DE TRAITEMENT D'IMAGE AVEC CELUI-CI
(JA) ズームレンズ系及びそれを備えた撮像光学機器
Abstract:
(EN) A zoom lens system composed of lens groups at least having a front lens group with negative power and a rear lens group with positive power, the rear lens group being placed nearer to the image side than the front lens group and having lens elements. The magnification of the zoom lens system is varied by varying the distance between the lens groups. The rear lens group has a rear A lens group movable in the direction normal to an optical axis and also has a rear B lens group provided nearer to the image side than the rear A lens group and movable in the direction of the optical axis so as to vary the distance between the lens B group and the lens A group, in the direction of the optical axis. The zoom lens system has high performance, is compact, light in weight, and low in costs, and has highly effective shaking correction function.
(FR) La présente invention concerne un système d'objectif à focale variable composé de groupes de lentilles ayant au moins un groupe de lentilles avant avec une puissance négative et un groupe de lentilles arrière avec une puissance positive, le groupe de lentilles arrière étant placé plus près du côté image que le groupe de lentilles avant et ayant moins d'éléments de lentille. L'agrandissement du système d'objectif à focale variable est varié en variant la distance entre les groupes de lentilles. Le groupe de lentilles arrière comporte un groupe de lentilles A arrière mobile dans la direction normale par rapport à un axe optique et comporte également un groupe de lentilles B arrière prévu plus près du côté image que le groupe de lentilles A arrière et mobile dans la direction de l'axe optique de façon à varier la distance entre le groupe B de lentilles et le groupe A de lentilles, dans la direction de l'axe optique. Le système d'objectif à focale variable offre des prestations élevées, est compact, d'un poids léger, et présente de faibles coûts, et comporte une fonction de correction des secousses hautement efficace.
(JA)  本発明のズームレンズ系は、負のパワーを有する前方レンズ群と、正のパワーを有し、該前方レンズ群よりも像側に配置され、複数のレンズ素子を含む後方レンズ群とを少なくとも備えた複数のレンズ群からなり、各レンズ群の間隔を変化させて変倍を行い、後方レンズ群が、光軸と垂直な方向に移動可能な後方Aレンズ群と、該後方Aレンズ群よりも像側に配置され、光軸方向における後方Aレンズ群との間隔を変化させるように光軸方向に移動可能な後方Bレンズ群とからなり、高性能で小型軽量化及び低コスト化が図られ、かつ、高いぶれ補正機能を有する。
