Vintage Early 1980's Sun 660 Auto Focus Model with Polaroid's patented Sonar Technology for sharper images. Comes with Approx. 60 Sheets of 4 x 6" Photo Paper. This camera has a battery system which employs a charging from the film packet to power to the camera for flash and film advance. You can not see how things work without a new film packet (i.e. power comes from film packet and charges camera). Because I do not have  film packet, I can not test any further. Everything looks clean with the rollers and gears and they turn. See pictures for details. Shipping is USPS. Email questions.
