Abstract:
(EN) This optical system which is used in an optical device such as a camera is configured to have a first lens group (G1) and a second lens group (G2) that has a positive refractive power. Therein, when focusing from an infinity object point to a close object point, the first lens group (G1) is fixed and the second lens group (G2) moves, said first lens group (G1) having a vibration reduction lens group that can move in a direction that includes the direction of a component that is orthogonal to the optical axis in order to correct imaging position displacement caused by hand shake, etc. Thanks to this, the present invention provides an optical system and optical device with which aberrations during vibration reduction are sufficiently corrected.
(FR) La présente invention concerne un système optique utilisé dans un dispositif optique tel qu'un appareil de prise de vues et qui est conçu de sorte à comporter un premier groupe de lentilles (G1) et un second groupe de lentilles (G2) présentant une réfringence positive. Selon l'invention, lors de la mise au point d'un point objet à l'infini à un point objet proche, le premier groupe de lentilles (G1) est fixe et le second groupe de lentilles (G2) se déplace, ledit premier groupe de lentilles (G1) comportant un groupe de lentilles à diminution de vibrations qui peut se déplacer dans une direction qui comprend la direction d'une composante orthogonale à l'axe optique afin de corriger un décalage de position d'imagerie provoqué par un tremblement de la main, etc. De cette manière, la présente invention pourvoit à un système optique et à un dispositif optique qui permettent de corriger suffisamment des aberrations apparaissant pendant une diminution de vibrations.
(JA)  カメラ等の光学装置に用いられる光学系において、第1レンズ群G1と、正の屈折力を有する第2レンズ群G2とを有し、無限遠物点から近距離物点への合焦の際、第1レンズ群G1が固定されて、第2レンズ群G2が移動し、第1レンズ群G1は、手ブレ等による結像位置変位の補正を行うために光軸と直交する成分方向を含む方向へ移動可能な防振レンズ群を有するものとする。これにより、防振時の収差を十分に補正した光学系および光学装置を提供する。
