    Abstract: A zoom lens includes, in order from the object side, a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third lens unit having a positive refractive power. The first lens unit includes a negative lens and a positive lens. The zoom lens satisfies the following conditional expression (1): Σd13/ft

    Abstract translation: 变焦透镜从物体侧依次包括具有负屈光力的第一透镜单元,具有正折光力的第二透镜单元和具有正折光力的第三透镜单元。 第一透镜单元包括负透镜和正透镜。 变焦透镜满足以下条件表达式(1):&Sgr; d13 / ft <0.4(1)其中&Sgr; d13是包括在变焦透镜的第一至第三透镜单元中的透镜的厚度的总和 光轴,ft是整个变焦镜头系统在远摄端的焦距。
