Polaroid One Step (original) uses SX-70 instant film (serial CVC914DA)

With its single red button and rainbow stripe motif, the original 1977 Polaroid One Step is an iconic instant camera. The Financial Times ran a piece on this model in 2017, hailing it a design classic. 

It's a very simple camera, it has a fixed focus lens where everything from 4 feet to infinity should be in focus in good light. Apart from the shutter, its only control is a brighten/darken dial. This camera uses Polaroid Originals SX-70 type films. We recommend using this camera outdoors in bright light for best results. Alternatively a compatible flash can be fitted for indoor use (not included).
