Polaroid Pronto Sonar OneStep

The Pronto Sonar OneStep represents a significant step forward in consumer instant photography during Polaroid's golden era. Released in 1976 as part of the mid-range Sonar series, it introduced the pioneering Sonar Autofocus system to the mainstream market. This technology, utilizing sound waves to measure distance, dramatically simplified focusing for users, eliminating one of the biggest hurdles in instant photography and making high-quality snapshots accessible to a wider audience. Styled with the characteristic sleek, functional design typical of 1970s Polaroids, it featured a fixed-focus lens once the Sonar engaged, housed in a compact and lightweight body built primarily of plastic. It used the standard Polaroid Pack film, producing the distinctive black-and-white prints that defined the era's instant aesthetic. While lacking the folding complexity or integral film processing of the flagship SX-70, the Pronto Sonar OneStep offered a practical, reliable, and technologically advanced point-and-shoot experience for families and casual photographers seeking instant results without manual focus adjustment.
