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。
