A waterproof casing contains a lens-fitted photographic film unit in a watertight manner so as to take underwater photograph. The waterproof casing is provided with an air flow opening. An air-permeable waterproof sheet is attached to the air flow opening form the inside so that air can pass through the sheet freely so as to regulate the internal pressure of the waterproof casing but water will not enter the waterproof casing. In a preferred embodiment, the waterproof casing consists of a transparent main body with a bottom opening and a bottom lid. The air flow opening is formed os as to be covered by a film winding knob of the waterproof casing. Structure to be fitted in the bottom opening is formed with another air flow opening to which the air-permeable waterproof sheet is attached. Outside this structure is disposed a waterproof sheet having an opening at a position facing the air flow opening of this structure. The waterproof sheet is covered by the bottom lid.

Waterproof casing

A camera having a standard taking lens and a macro lens which are held in a lens holder rotatable in a plane perpendicular to the photographic light path, whereby either one of standard and macro lenses can be inserted selectively into the light path. The macro lens is smaller in diameter than the standard lens so as to distinguish the lenses from each other during manufacture and assembly. When the macro lens is placed in the photographic light path, switching means turns a charge switch on, thereby to charge a main condenser for flashing. In macrophotography, upon depression of a shutter release button, flash light is automatically emitted.
