A viewfinder for a reflex camera for viewing the image formed through an objective lens comprises a reflecting member for reflecting a light flux from the objective lens in a predetermined direction, a transparent member for passing the reflected light therethrough, and a mat surface located at the exit side of the transparent member and convexly curved toward the entrance side of the transparent member. Thus, the image plane formed by the light flux passed from the objective lens through the transparent member is coincident with the mat surface convexly curved toward the entrance side.
