Abstract:
An imaging optical system includes a plurality of lens groups each moving such that spaces between each one of the plurality of lens groups change during a zooming. The imaging optical system conjugates a conjugate point on a magnification side and an intermediate imaging position, and conjugates a conjugate point on a reduction side and the intermediate imaging position. The imaging optical system includes a first lens group located at a furthest place on the magnification side and a rear group in this order from the magnification side toward the reduction side. The first lens group includes a field curvature correction lens group moving along an optical axis when an amount of a field curvature is changed, and a focusing lens group. The imaging optical system satisfies condition (4) below: |{(1− βcw 2 )×β crw 2 }/{(1−β fw 2 )×β frw 2 }|<0.2   (4)

Claim (Index 11):
The imaging optical system according to  claim 10 , wherein the imaging optical system satisfies condition (8) below:\n 2.0<| f 4/ ft|<b  10 . 0   \u2003\u2003(8) where, f 4  is a focal length of the fourth lens group; and\n ft is a composite focal length of a total system at a telephoto end.
