Abstract

　本発明のズームレンズ系は、物体側から正パワーの第１レンズ群、負パワーの第２レンズ群、正パワーの第３レンズ群、正パワーの第４レンズ群を備え、ズーミング時に第１～４群全てが光軸に沿って移動し、第３レンズ群が３枚以上のレンズ素子で、条件（６）：ｎｄ８≦１．５かつｖｄ８≧７５及び（７）：（ｎｄ９－１）＋（ｎｄ１０－１）≧１．５５（１６＜ｆＴ／ｆＷ、ω＞３５、第３レンズ群において、ｎｄ８、ｎｄ９、ｎｄ１０：最物体側、物体側から２番目、３番目のレンズ素子のｄ線に対する屈折率、ｖｄ８：最物体側のレンズ素子のｄ線に対するアッベ数、ω：広角端での半画角、ｆＴ：望遠端での全系の焦点距離、ｆＷ：広角端での全系の焦点距離）を満足し、小型でありながら広角端での画角が広く、ズーミング比が極めて高く高性能である。
