ABSTRACT:
Disclosed is a zoom lens which is composed of a plurality of groups of lenses and which varies the power thereof by changing inter-group spacings. The zoom lens is configured such that: the last group of lenses that is located at the end of an image space and is negatively refractive is held stationary in optical-axis directions during variation of the power of the zoom lens, and includes a front group of negative lenses and a rear group of positive lenses; and the rear group of positive lenses or part of the rear group of positive lenses (hereinafter, referred to as a group of blur compensation lenses) is movable in directions orthogonal to the optical axis of the zoom lens. In this configuration, the group of blur compensation lenses is moved in the directions orthogonal to the optical axis in order to shift an image.
