摘要： A zoom lens is composed of a first lens group of a negative refractive power, a second lens group of a positive refractive power and a third lens group of a positive refractive power, in which, in the zooming operation from the wide angle end to the telephoto end, the distance between the first and second lens groups decreases and the distance between the second and third lens groups varies.

摘要： A zoom lens structured so that a substantially constant amount of movement of a focusing lens group is required for focusing on objects at the same distance regardless of the zoom position even when an inner focusing method is implemented. The zoom lens includes in order from an object side, a first lens group which has a negative refractive power and a second lens group which has a positive refractive power, wherein zooming is executed by changing a distance between the first lens group and the second lens group, wherein the second lens group includes, in order from the object side, a front group which has a positive refractive power and a rear group which has a positive refractive power, and wherein focusing from an object at a far distance to an object at a close distance is executed by moving the front group towards an image side.
