Zoom lens and imaging apparatus

Abstract

The present disclosure provides a zoom lens having a wide angle of view at the wide angle end, a small F value throughout the entire zoom range, which favorably corrects various aberrations. The present disclosure also provides an imaging apparatus equipped with such a zoom lens. The zoom lens is constituted by, in order from the object side: a positive first lens group (G1); a negative second lens group (G2); a positive third lens group (G3); a negative fourth lens group (G4); and a positive fifth lens group (G5). The distance between the first and second lens groups constantly increases, the distance between the second and third lens groups constantly decreases, the distance between the third and fourth lens groups constantly changes, and the distance between the fourth and fifth lens groups constantly increases when changing magnification from the wide angle end to the telephoto end. The first lens group (G1) is constituted by three lenses, which are negative, positive, and positive in order from the object side. The second lens group is constituted by five lenses, which are negative, negative, positive, positive, and negative in order from the object side. The fifth lens group is constituted by a single lens component.

Description

technical field [0001] The present invention relates to a zoom lens particularly suitable for a digital camera, a lens interchangeable digital camera, a camera for cinematography, and the like, and an imaging device including the zoom lens.
