Abstract

　十分なコンパクト化を達成しつつ、レンズの製造難易度を従来と同程度に抑えた変倍光学系を提供する。変倍光学系は、物体側から順に、負の光学的パワーを有する第１レンズ群と、正の光学的パワーを有する第２レンズ群とを含み、広角端から望遠端への変倍時に第１レンズ群と第２レンズ群との間隔が狭くなる変倍光学系である。第１レンズ群は負レンズ及び正メニスカスレンズで、第２レンズ群は両凸正レンズ及び負メニスカスレンズで構成されている。そして、第１レンズ群のレンズ最前面から第１レンズ群のレンズ最後面までの光軸ＡＸ上の厚みをＤ１、当該変倍光学系の広角端での全光学系の合成焦点距離をｆｗ、第２レンズ群の合成焦点距離をｆ２とするとき、次の関係を満たすように構成される。 　　０．５＜Ｄ１／ｆｗ＜０．８ 　　０．７＜ｆ２／ｆｗ＜２．０
