PROBLEM TO BE SOLVED: To provide a film unit with a lens capable of switching a photographing focusing position. SOLUTION: A lens base 33 is freely turnably attached to a cylindrical part 32. A cam part 36 is formed on the part 32. A photographing lens 8 is pressed along an optical axis direction L to a shutter cover 31 side by a coil spring 34. A protruding part 33e is provided on the base 33. The part 33e is pressed to the cam part 36 by the pressing of the spring 34. The part 36 is constituted of a normal photographing cam surface 36a, an inclined cam surface 36b, and a distance view photographing cam surface 36c. The lens base 33 is pressed clockwise by a coil spring 35, and the base 33 is set on the normal photographing position. The base 33 is rotated counterclockwise by a focusing switching knob 11 through an arm part 33c and is set on a distant view photographing position. Since the focusing switching mechanism is provided, the extent of blur can be reduced even though a bright lens having a small F value is used.
