PROBLEM TO BE SOLVED: To form a camera having two optical systems such as a single-lens reflex type having one eyepiece in common and a range finder type. SOLUTION: The camera in which a mirror is assembled, whose front side a lens barrel is attached to, and also which has a mirror housing part provided with an exposure surface on a back side has a single-lens reflex type finder optical path forming a visible image which can be observed by an eyepiece having an optical axis which does not share a plane with the optical axis of a condenser lens through the condenser lens, a prismatic prism and a relay lens from an image reflected from the mirror and formed on a focusing glass at a position conjugate to the exposure surface, and a range finder type finder optical path forming the visible image which can be observed by the eyepiece from a double image composed of a real image formed by a prism having a roof surface and a convex lens and a virtual image formed by a concave lens.
