PROBLEM TO BE SOLVED: To freely separate subject light in accordance with an attaching position of a functional unit.SOLUTION: In accordance with a photographing scene, any of a plurality of functional units 12 to 14 is attached to a camera body 11 and used. A semi-transmissive mirror 19 is rotatable to a plurality of rotation positions between an imaging lens 21 and an imaging part 18, and is rotated to any of the rotation positions, thereby a part of subject light is branched to any of a plurality of branch positions. A plurality of attachment parts 16 and 17 is respectively provided at a position corresponding to the plurality of branch positions, and has any of the plurality of functional units 12 to 14 freely detachably attached. A rotation position determination part determines positions of the attachment parts 16 and 17 to which the functional units 12 to 14 are attached of the attachment parts 16 and 17 or a rotation position of the semi-transmissive mirror 19 in accordance with a type of the attached functional units 12 to 14. |
