<p>Provided is a zoom lens which exhibits a reduction in size, increased magnification, and a reduction in variation of angle of view during zooming, and which is capable of easily achieving an increased focusing speed, said zoom lens being suitable for an imaging apparatus using a solid-state imaging device such as an interchangeable lens, a digital still camera, a digital video camera, or the like. The zoom lens has, in the lens system thereof, at least: a first negative lens group having negative refractive power; a second negative lens group which is disposed further towards the image side than the first negative lens group, and which has negative refractive power; and a lens group (A) which is disposed so as to be adjacent to the image side of the second negative lens group. In the zoom lens, focusing from an infinite distance to a near object is performed by moving only the second negative lens group towards the image side, and prescribed conditions are satisfied.</p> |
