PROBLEM TO BE SOLVED: To enable a user himself (herself) to select the propriety of strobe light emission, to obtain an appropriate main object/background density ratio in the case of photographing in a room or at night and to provide a desirable photograph within appropriate exposure in the case of photographing in the daytime or outdoors. SOLUTION: This film unit with a lens is equipped with a photographing mechanism having a photographing lens, a fixed speed shutter device, a diaphragm and a stroboscopic device, and unexposed photographic film is previously loaded in the film unit with a lens. When it is assumed that the shutter speed of the shutter device is T seconds, and the guide number of the stroboscopic device is G (ISO100.m), the film unit satisfies relation being 7.0<=log2(G2)+ log2(1/T)<=12.5 and is equipped with a photometry means outputting a light quantity signal in accordance with the light quantity of an object, and an adjusting mechanism changing exposure to photographic film in accordance with the light quantity signal. The photographic film has at least one photosensitive silver halide emulsion layer incorporating silver halide emulsion whose average aspect ratio is >=4.0. |
