Design Features
The SX-70 included many sophisticated design elements. A collapsible SLR required a complex light path for the viewfinder, with three mirrors (including one Fresnel reflector) of unusual, aspheric shapes set at odd angles to create an erect image on the film and an erect aerial image for the viewfinder. Many mechanical parts were precision plastic moldings. The body was glass-filled polysulfone, a very rigid plastic which could be plated with genuine copper-nickel-chromium. Models 2 & 3 used the less expensive and more-easily cracked ABS in either Ebony or Ivory color. 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 (five on each side, with the user rotating the bar half way through) from General Electric, used logic circuits to detect and fire the next unused flash.
