This camera was introduced in the Sears catalog in 1977. The solid body One Step was also introduced by Polaroid at that time. The One-Step is in the same family as the SX-70 using SX-70 film. It was much less expensive and had many fewer features, however. It has a solid, instead of folding, body, with a simple direct viewfinder. According to The Land List, it has a single element 103mm f14.6 plastic, fixed focus, lens. Also it has an electronic shutter with programmed auto exposure. A flash bar with ten flashes can be inserted on the top or a strobe made by Polaroid to fit. The suggested retail price was $39.95, about $200 in 2020 dollars. The film pack includes the battery and is needed to test the shutter. You will not find any difference between the regular One Step and the One Step Sears Special other than “Sears Special” printed in small red letters over the film exit slot.
