发明名称 SINGLE-LENS REFLEX CAMERA USING PHASE DIFFERENCE DETECTION METHOD
摘要 A single-reflex camera includes a mirror box, and a focus detecting unit. The mirror box further includes a first opening on a side of the image-pickup optical system, which the light flux that has passed the image-pickup optical system enters, and a bottom plate arranged between the mirror and the focus detecting unit, the bottom plate including a plate-shaped front part that extends so as to approach to an optical axis of the image-pickup optical system from the first opening. Part of the condenser lens is located on a side of the optical axis of the image-pickup optical system with respect to a line that is made by extending, parallel to the optical axis of the image-pickup optical system, an end of the first opening on a side of the bottom plate.
