摘要： An object of the present invention is to provide: a zoom lens system that has a high resolution, high capability of compensating curvature of field, a high zoom ratio of, for example, 3 or greater, a reduced weight, and a reduced overall optical length at the time of non-use; and an imaging device and a camera that employ this zoom lens system so as to have a reduced thickness and excellent portability as well as high performance. The zoom lens system forms an optical image of an object with variable magnification and, in order from the object side to the image side, comprises: a first lens unit having negative optical power; a second lens unit that has positive optical power and that contains a bi-convex lens element composed of a resin material and serving as the most image side lens element; and a third lens unit having positive optical power. Then, the lens units move respectively along the optical axis in such a manner that intervals between the individual lens units should vary so that the variable magnification is achieved. Further, the condition |(R2mi1+R2mi2)/(R2mi1−R2mi2)|

摘要： A zoom lens system is provided that includes a compactly constructed focusing lens unit and that has a suppressed change in the image magnification at the time of movement of a focusing lens unit. The zoom lens system according to the present invention, in order from an object side to an image side, comprises: a first lens unit having positive optical power; a second lens unit having negative optical power; a third lens unit having positive optical power; and an aperture diaphragm. At the time of zooming, the zoom lens system moves the first to third lens units so that intervals between these lens units vary. At the time of focusing from an infinity in-focus condition to a close-point object in-focus condition, the zoom lens system moves the third lens unit to the object side.
