Electronic imaging apparatus

An electronic imaging apparatus comprising:

• a zoom optical system including, in order from an object side, a first lens unit with negative power and a second lens unit with positive power, in which lens components having refracting power in the first lens unit are only a single biconcave negative lens element located at a most object-side position and a positive lens component located at a most image-side position;
• an electronic image sensor placed on an image side of the zoom optical system;
• and
• an image processing section electrically processing image data obtained by the electronic image sensor to change a shape thereof,
• the zoom lens system satisfying the following condition in focusing of a nearly infinite object point:
• 0.85<y07/(fw·tan ω07w)|<0.97
• 0.75<y10/(fw·tan ω10w)|<0.93
• where fw is a focal length of an entire zoom optical system at a wide-angle position, y10 is a distance from a center of an effective imaging surface to a point furthest from the center of the electronic image sensor, y07 is an image height expressed by 0.7 y10, ω07w is an angle made by a direction of an object point corresponding to an image point, connecting the center of the effective imaging surface of the electronic image sensor at the wide-angle position and the position of the image height y07, with the optical axis, and a lens component is such that only a most object-side surface and a most image-side surface thereof come in contact with air and there is no air spacing between both surfaces, taking a single lens element or a cemented lens component as one unit.
