Zusammenfassung:PURPOSE:To correct automatically parallax by providing an electro-mechanical converter which is displaced according to the distance measuring signal inputted from a range finder via a driving device and providing a finder visual field frame which is moved in the direction for correcting the parallax cooperatively with said displacement. CONSTITUTION:The focusing of a photographing film 1 for an object to a film 2 is accomplished by inputting the distance measuring signal from a range finder 3 to a focusing device 4 and moving the lens 1 toward the direction of arrow. A finder block 5 provided in the upper part of the lens 1 is constituted of an objective lens 6, an eyepiece lens 7, a semitransparent plane mirror 10, a visual field frame 8 provided with a finder visual field 8A, a total reflection plane mirror 9 which superposes the field 8A on the finder image of the object passing through the lens 6 and an electro-mechanical converter 11 which moves downward the frame 8 held movably in a vertical direction by as mush as the parallax against the energizing of a spring 12.
