Abstract: The invention makes a suitable selection from zoom modes and lens elements so thin that the thickness of each lens group can reduced, thereby slimming down a zoom lens with great thoroughness and, hence, an electronic image pickup system. The electronic image pickup system a zoom lens and an electronic image pickup device located on the image plane side of the zoom lens. The zoom lens comprises, in order from the object side, a first lens group G1 comprising two lens components and having generally negative power and a second lens group G2 comprising two lens components and having generally positive power. The focal length of the zoom lens can be varied by varying the air separation between the first lens group G1 and the second lens group G2. The zoom lens should satisfy at least one of conditions (a) to (n).

Abstract: The object of the invention is to reduce the thickness of electronic image pickup equipment as much as possible, using a zooming mode having stable, high image-formation capabilities from an object at infinity to a near-by object. The electronic image pickup equipment comprises a zoom lens system comprising a negative, first lens group G1, a positive, second lens group G2 and a positive, third lens group G3. For zooming from the wide-angle end to the telephoto end of the zoom lens system upon focused on an object at infinity, the separation between G2 and G3 becomes wise. By moving G3 toward the object side of the system, the system can be focused on a nearer-by object. In the zoom lens system, the second lens group G2 comprises one positive lens 2a, one negative lens 2b and a lens subgroup 2c comprising at least one lens, and the third lens group G3 comprises one positive lens. The zoom lens system satisfies conditions with respect to the optical axis distance from the image-side surface of the positive lens 2a to the image-side surface of the negative lens 2b and the focal length ratio in air between the positive lens 2a and the lens subgroup 2c.
Abstract translation: 本发明的目的是尽可能减小电子摄像设备的厚度，使用具有从无穷远到近距离物体的物体具有稳定的高成像能力的变焦模式。 电子摄像设备包括一个变焦透镜系统，它包括负的第一透镜组G1，正的，第二透镜组G2和正的第三透镜组G3。 为了在聚焦在无限远的物体上时从变焦镜头系统的广角端到望远端的变焦，G2和G3之间的分离变得明智。 通过将G3移动到系统的物体侧，系统可以集中在更近的对象上。 在变焦透镜系统中，第二透镜组G2包括一个正透镜2a，一个负透镜2b和包括至少一个透镜的透镜子组2c，并且第三透镜组G3包括一个正透镜。 变焦透镜系统满足关于从正透镜2a的像侧表面到负透镜2b的像侧表面的光轴距离和正透镜2a与透镜之间的空气焦距比的条件 子组2c。
