Abstract:
An imaging optical system includes a first lens group having positive power, a second lens group, and a third lens group. The first lens group includes a sub-lens group G1A, an aperture stop, and a sub-lens group G1B. The sub-lens group G1A includes a lens L1A1 and a lens L1A2. An object-side surface of the lens L1A1 is convex toward an object. The third lens group includes a lens L3E having negative power and a lens L3P located adjacent to, and closer to the object than, the lens L3E.
