PROBLEM TO BE SOLVED: To change finder magnification in accordance with the switching of lenses whose focal distances are different. SOLUTION: This film unit is provided with a finder magnification changing mechanism 73 changing the finder magnification in response to the switching of the lens of a lens switching mechanism 36. The mechanism 36 rotates a lens holder 38 in response to the operation of an outside operating member and positions either of photographing lenses 40 and 41 having different focal distances on a photographing optical axis 13a. The mechanism 73 moves a movable lens 64 by utilizing the rotation of the holder 38 between an objective lens 63 and an eyepiece lens 65 along a finder optical axis 62a, and changes the finder magnification of the finder optical system to magnification in accordance with the lens positioned on the axis 13a.
