ABSTRACT:
There is disclosed a camera having a first imaging medium which acquires subject image data from a subject light flux transmitted through a photographing lens; an optical path branching member which is disposed in an image pickup optical path of the first imaging medium to branch an optical path of the subject light flux; a primary image forming surface on which the subject light flux branched by the optical path branching member forms an image; and a second imaging medium which picks up the subject image formed on the primary image forming surface. When the present camera satisfies at least one of a plurality of optical conditions, the amount of shading of the light flux guided to the second imaging medium is reduced.
