Abstract:
1. An electronic imaging system comprising a zoom lens comprising a plurality of lens groups wherein a space between adjacent lens groups is variable during zooming or focusing, and a lens group G 1 nearest to an object side of the zoom lens comprises two components consisting of a negative lens component and a positive lens component, each having an aspheric surface, and an electronic image pickup device located on an image side of the zoom lens, wherein an image formed through the zoom lens can be produced as an image data output wherein image data obtained by picking up the image at the electronic image pickup device are processed to change shape, wherein: the zoom lens satisfies the following condition: where y 08 *=0.8y 10 * provided that y 10 * is a distance (maximum image height) from a center to a farthest point in an effective image pickup plane (capable of picking up an image) of the electronic image pickup device, and ω 08W is an angle at a wide-angle end of the zoom lens of an object point with respect to an optical axis of the zoom lens, wherein the object point corresponds to an image point of connecting a center on the image pickup plane with a y 08 * position.
