PROBLEM TO BE SOLVED: To easily attain regular panoramic photographing and to easily develop and print out panoramic photographs. SOLUTION: A pin 5a is erected on an axial line orthogonal to an optical axis from a position coincident with a main point of a zoom lens in a back lens holding cylinder 5 of the zoom lens, one-end parts of a plurality of arms 7 are orthogonally fixed on the vertical edge part of an aperture forming member 6, and a slot 7a formed on the other end parts of the arms 7 is engaged with the pin 5a. The focal distance of the zoom lens is conformed to the radius of circular arc shape of a film consisting of an aperture forming member. A motor 9 is coupled to the pin 5a. When the focal distance is changed by displacing the pin 5a, the radius of the circular arc shape of the film is changed in accordance with the focal distance, and when the mirror barrel 2 is swung around the focal distance which is the radius, photographing based on photographing angles including a human natural visual field range (90°) and photographing angles corresponding to panoramic photographing (100-130°) can be easily performed.
