Title (EN) ZOOM LENS SYSTEM, IMAGE CAPTURING DEVICE AND CAMERA
(FR) SYSTÈME DE LENTILLES DE BOURDONNEMENT, DISPOSITIF DE CAPTURE D'IMAGE ET CAMÉRA
(JA) ズームレンズ系、撮像装置及びカメラ
Abstract:
(EN) A zoom lens system is provided with, in order from the object side to the image side, at least a first lens group having positive power, and a second lens group having negative power, increases the distance between the first lens group and the second lens group during zooming from a wide angle end to a telephoto end when an image is captured, and satisfies conditions: D1>D2 and D3>D2 at the same time, where D1 is the effective diameter of an aperture stop at the wide angle end, D2 is the effective diameter of the aperture stop at an intermediate position, and D3 is the effective diameter of the aperture stop at the telephoto end.
(FR) La présente invention porte sur un système de lentilles de bourdonnement muni de , dans l'ordre depuis le côté objet vers le côté image, au moins un premier groupe de lentilles ayant une réfringence positive et un second groupe de lentilles ayant une réfringence négative, augmentant la distance entre le premier groupe de lentilles et le second groupe de lentilles pendant le bourdonnement d'une fin de type grand angle à une fin de type téléphoto lorsqu'une image est prise, et remplit les conditions suivantes : D1>D2 et D3>D2 en même temps où D1 représente li diamètre effectif d'un diaphragme au niveau de la fin de type grand angle, D2 représente le diamètre effectif de diaphragme à une position intermédiaire et D3 représente le diamètre effectif du diaphragme au niveau de la fin de type téléphoto.
(JA)  物体側から像側へと順に、正のパワーを有する第1レンズ群と、負のパワーを有する第2レンズ群とを少なくとも備え、撮像時の広角端から望遠端へのズーミングの際に、第1レンズ群と第2レンズ群との間隔を増大させ、条件:D1>D2及びD3>D2(D1:広角端における開口絞りの有効径、D2:中間位置における開口絞りの有効径、D3:望遠端における開口絞りの有効径)を同時に満足するズームレンズ系。
