Claim 23:
24. The zoom lens according to claim 23, wherein
a stop is disposed closest to the object side in the middle group or is disposed inside the middle group,
a distance on the optical axis from the stop to the lens surface as the convex surface at the wide angle end in the state where the infinite distance object is in focus is DStw,
a focal length of the rear subgroup at the wide angle end in the state where the infinite distance object is in focus is fMrw, and
the rear subgroup includes one or more lens surfaces as the convex surfaces satisfying Conditional Expression (6), which is represented by
