Patent ID: 7956901

Claim:
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 from a part of a reflective surface of a penta-dach mirror and by re-forming the optical image on a live-view imaging device, a live-view optical system positioned between an opening of the penta-dach mirror and the live-view imaging device, and which re-forms light reflected from the part of the reflective surface on the live-view imaging device, and characterized in that a position of an entrance pupil satisfies the following conditional expression (1): 0.75<(( Dp/ 2 −Y )· Za )/(( Ra/√ 2 −Y )· Zp ) (1) where Dp 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.
