Designed for Polaroid's 600-series integral film in 1988, the Impulse models are similar in body design to the “OneStep +”, “OneStep 2” or “Pronto!”, models released that feature a non-folding plastic body, a single-element plastic lens with a fixed aperture (116mm, f9), and fixed focus. The basic Impulse model is usually found in a dark gray color, but there were a variety of different colors of Impulse released including yellow, red, green, black, blue, purple, plum, and light gray. Some autofocus models were also made which were designated as Impulse AF like the one pictured and they feature higher quality 3-element lenses. The body is a hard-wearing plastic and features rubber grips around the rear, a tripod-socket, plus flash-ready LED and film counter. The flash is raised by pressing down onto the top of the unit; this also turns the camera on and retracts the lens cover. This camera also has a 4-foot minimum focus distance, Exposure compensation controls below the lens, viewfinder, and a handy carry strap.
