Patent ID: 6995922

Claim:
A zoom lens comprising: a lens unit located at a most object-side position; and a moving lens unit with positive refracting power, located on an image side of the lens unit, the lens unit including a single positive lens and the moving lens unit being simply moved toward an object side when a magnification of the zoom lens is changed in a range from a wide-angle position to a telephoto position so as to satisfy the following condition: 0.8 <y 07 /( fw ·tan ω 07w )<0.96 where fw is a focal length of an entire system of the zoom lens at the wide-angle position, y 07 is an image height expressed by 0.7×y 10 , where y 10 is a distance from a center to a point farthest therefrom on an effective imaging surface of an electronic image sensor, and ω 07w is an angle made by a direction of an object point with an optical axis, where the object point corresponds to an image point that is at the point y 07 away from the center on the effective imaging surface of the electronic image sensor at the wide angle position.
