The camera features a folding bellows and auto exposure. The camera does not have a typical rangefinder viewfinder with a double image. Instead of being a true rangefinder, this particular model has a simplified "image sizer" that is used as a focusing aid for portrait shots. There are two horizontal lines in the viewfinder, and one remains stationary while the other shifts up and down as the camera is focused. This allows the shooter to adjust the focus so the subject's head fits between the two lines, thus resulting in a properly composed image. The Polaroid Automatic 104 uses a 532 3V battery, and 100 series packfilm (FujiFilm's FP-100C is readily available today). Another neat vintage find!
