ABSTRACT:
A live-view optical system A is, in an image capture apparatus capable of obtaining an image of an object in a moving picture mode by reflecting an optical image formed on a focusing plate D from a part of a reflective surface F of a penta-dach mirror B and by re-forming the optical image on a live-view imaging device H, positioned between an opening G of the penta-dach mirror and the live-view imaging device, and re-forms light reflected from the part of the reflective surface on the live-view imaging device, whereina position of an entrance pupil K satisfies the following conditional expression (1).in-line-formulae description="In-line Formulae" end="lead"?0.75<((Dp/2−Y)·Za)/((Ra/√2−Y)·Zp) (1)in-line-formulae description="In-line Formulae" end="tail"?whereDp is a diameter of the entrance pupil of the live-view optical system, Zp is a distance from the focusing plate to the entrance pupil of the live-view optical system, Y is a maximum image height on the focusing plate, Za is a distance from the focusing plate to the opening of the penta-dach mirror, and Ra is a distance from an optical axis of the live-view optical system to a dach ridgeline.
