Polaroid SX-70 Sonar One Step

The Polaroid SX-70 Sonar One Step is an instant film camera in the SLR-bodied SX-70 family, distinguished by its ultrasonic Sonar autofocus system. Introduced in the late 1970s, it was positioned as a more advanced, autofocus-equipped variant of the folding SX-70 line.

Sales data for the SX-70 Sonar One Step is thin: a single July 2025 hammer result of £56 at UK auction is the only verified data point available, so today's market value is best framed by that one wholesale saleroom outcome rather than a true range. Buyers researching what an SX-70 Sonar One Step is worth or sells for in 2026 should treat that £56 figure as indicative only, and expect condition, working electronics, and the presence of original leatherette to swing the price meaningfully.

Frequently asked questions

What is a Polaroid SX-70 Sonar One Step worth today?

Based on the limited UK auction evidence available, a working example hammered at £56 in mid-2025; with only one verified sale, that figure is the best current reference for value rather than a firm market price.

How much does a Polaroid SX-70 Sonar One Step sell for at UK auction?

The only verified recent UK hammer price on file is £56 from July 2025, so any quoted price range would be speculative beyond that single data point.

What makes the Sonar One Step different from a standard SX-70?

The Sonar variant adds an ultrasonic autofocus system mounted on the front of the viewfinder housing, whereas the original SX-70 is manual focus.
