1978 Polaroid 1000 commercial.
Alongside the ‘prosumer’ range of folding SLRs, Polaroid released a large number of plastic bodied, non-folding consumer cameras that used the SX-70 integral film. There were several lines that varied in the type and amount of features they offered, but fall into three distinct categories differentiated by the method of focusing:
- Fixed focus – Generally known (in the US) as OneStep models
- Zone-focused – Generally known (in the US) as Pronto! models; e.g. Pronto RF
- Sonar Autofocus – Labelled as both Pronto! and OneStep models, but usually with an AF or Sonar moniker.
All these models use the SX-70 integral film, meaning the camera is powered by a battery built into the film pack. Many of these models were able to use certain accessories designed for the folding SLR line of SX-70 cameras, such as flashbars, electronic flashes and tripod mounts.
The Land Camera 1000 is a foreign-markets version of the original Onestep model, meaning it has a fixed focus plastic lens. The model 1000 or original OneStep models are distinguished among the range in that they were made available with 2 different coloured shutter buttons – either green or red; there is some debate among collectors as to which was more common. A matching electronic flash was also released for the Onestep/1000 model, known as the Q-Light. It fits onto any SX-70 non-folding camera model, but was cosmetically matched to the original models.
