Abstract:
The present invention provides a zoom lens that can perform favorable correction of chromatic aberration in the entire zoom range, and can have higher performance and a smaller size than conventional ones; and an imaging apparatus including the zoom lens. To achieve the object, provided are a zoom lens and an imaging apparatus including the zoom lens. The zoom lens includes, in order from an object side: a positive first lens group G 1 ; a negative second lens group G 2 ; and a GR group including one or more lens groups. In the zoom lens, changing focal length is performed by varying intervals between the lens groups. The GR group has at least two cemented surfaces having negative refractive power, convex lenses GpH and GpL satisfying predetermined conditional expressions. An aperture stop is arranged in the first lens group or after. The zoom lens satisfies predetermined conditional expressions.

Claim (Index 5):
An imaging apparatus, comprising:\n a zoom lens according to  claim 1 ; and an imaging device arranged on the image side of the zoom lens and configured to convert an optical image formed by the zoom lens to electrical signals.
