Abstract

The invention provides a zoom lens and an electronic camera device using the zoom lens. This zoom lens has: the first lens group with positive refractive power; the second lens group with negative refractive power; and the third lens group with positive refractive power. The interval between the second group (G2) and the interval between the second group (G2) and the third group (G3) are changed. Compared with the wide-angle end, the first group (G1) and the second group (G2) The distance between them becomes wider at the telephoto end, and the distance between Group 2 (G2) and Group 3 (G3) narrows at the telephoto end than at the wide-angle end.

Description

[0001] This application claims priority from Japanese Patent No. 2006-252569 filed on September 19, 2006 and Japanese Patent No. 2006-290117 filed on October 25, 2006, the contents of which are incorporated herein by reference In this application. technical field [0002] The present invention relates to a zoom lens and an electronic imaging device using the zoom lens. Background technique [0003] In recent years, instead of silver halide film cameras, digital cameras that use electronic imaging elements such as CCD image sensors (CCD image sensors) and CMOS type image sensors (CMOS type image sensors) to capture subjects have become mainstream. Furthermore, it has various types in a wide range from a high-performance type for business use to a small popular type. [0004] Users of popular digital cameras want to be able to conveniently enjoy shooting in various scenes anytime, anywhere. Therefore, small-sized products, especially digital cameras that are easy to carry in...
