To perform enlarged printing at a low cost, using a simple constitution.

This film unit with a lens is provided with a finder magnification changeover switch. By operating the finder magnification changeover switch, finder magnification is changed over between standard magnification and telephotographic magnification. At the same time, the number of PAR bits 28 inputted onto photographic film 23 by a mark exposure device is changed over. At carrying out standard photography, two bits 28 are inputted onto the film 23. At carrying out telephotography, a subject image enlarged 1.63 times as large as that at the time of standard photography is observed in finder field, and three bits 28 are inputted onto the film 23. When two bits 28 are detected at the printing a picture, printing in the range 29 is performed on printing paper of size C, by using a magnification lens (magnification of 5.7) of standard size and a paper mask. When three bits 28 are detected, printing is performed on the printing paper of size C, by using a magnification lens (magnification is 9.3) for panoramic printing.
