Abstract:
Provided are: a zoom lens including, in order from an object side, a first lens group having positive refractive power, a second lens group having negative refractive power, an Intermediate group having one or more lens groups and having positive refractive power as a whole, a lens group having negative refractive power, and a rear group having one or more lens groups, wherein the intermediate group includes at least two lens surfaces each of which is a cemented surface and is a diverging surface, a space between adjacent lens groups changes in zooming, the lens group moves on an optical axis in focusing, and the zoom lens satisfies the predetermined conditional expression; and an imaging apparatus including the zoom lens.
