Imaging device and digital camera using the imaging device
First Claim
1. An imaging device comprising:
- a zoom lens system having a plurality of lens units and forming an optical image of an object so as to continuously optically zoom by varying distances between the lens unit; and
an image sensor converting the optical image formed by the zoom lens system to an electric signal, wherein the zoom lens system comprises from an object side;
a first lens unit being overall negative and including a reflecting surface that bends a luminous flux substantially 90 degrees; and
a second lens unit disposed with a variable air distance from the first lens unit, and having an optical power, and wherein at least one lens element made of resin is included in the entire lens system.

Abstract
An imaging device has a zoom lens system having a plurality of lens units and forming an optical image of an object so as to continuously optically zoom by varying distances between the lens unit; and an image sensor converting the optical image formed by the zoom lens system to an electric signal. The zoom lens system has from an object side, a first lens unit being overall negative and including a reflecting surface that bends a luminous flux substantially 90 degrees; and a second lens unit disposed with a variable air distance from the first lens unit, and having an optical power, and wherein at least one lens element made of resin is included in the entire lens system.
