Ultra Swank - Retro Adventures

Polaroid SX-70 Promotional Film

Written by Christopher Alm • February 10th, 2010

This short promotional film, produced in the early 1970s gives us a insight into how the classical compact Polaroid SX-70 camera functions.

The SX-70 included many sophisticated design elements. A collapsible SLR required a complex light path, with many mirrors (including one Fresnel reflector) of unusual, aspheric shapes and at odd angles. The film pack contained a flat, 6-volt “PolaPulse” battery to power the camera electronics, drive motor and flash. The original flash system, a disposable “Flash Bar” of 10 bulbs from General Electric, used logic circuits to detect and fire the next unused flash.

    I always wanted one back in the day. I have one now in my collection. By the time I got my first really good camera at 17 I went with the Pentax ME.

  • Lucky you, Lee! I always thought that Polaroid cameras were the coolest, wish I had one.
