摘要： 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.

摘要： A digital camera having an image shake correction apparatus and a method of preventing the image shake of an image taken by the digital camera. The digital camera includes optical elements arranged along a bent line for focusing an object image upon a light receiving plane in which the elements include at least one mirror which reflects a light from an object toward the light receiving plane, a driver for moving the mirror so as to turn its light axis having been bent by the mirror, a vibration sensor for sensing a vibration of a camera body, and a processor for making the driver move the mirror based on the sensed vibration. The mirror turns so as to cancel the vibration of the object image focussed on the light receiving plane.
