Have you seen Memento? You should if not. It's a great film that uses amnesia as key plot device, and a Polaroid camera as another. The camera in question is an SLR 690, which featured a sonar auto focus systems, and marked the end of the line for the ingenious collapsible Polaroid SX range, a promotional video of which can be seen here. If you struggle with the length of the video, at least skip to 4min 50sec and enjoy leaning how the single lens reflex mirror system works. Furthermore, to see one in the flesh, why not pop in to see us sometime as we have one on display!
