Polaroid Pronto SE1977

History

Polaroid's SX-70, launched in 1972, introduced the world to integral instant film: a self-contained chemical sandwich that developed in daylight without the peel-apart waste of the pack-film era. The SX-70 was brilliant but expensive, and Polaroid needed a lower-cost rigid-body camera to expand the market. The OneStep (1977) accomplished this for the basic consumer tier, while the Pronto series - Pronto B, Pronto SE - added differentiated features at stepped price points.

The SE's headline addition over the base Pronto B was the sonar autofocus module: an ultrasonic transducer mounted above the lens that emitted a pulse and timed the echo to calculate subject distance. This system, first deployed on the SX-70 Sonar, allowed users with no photographic training to achieve correctly focused shots regardless of subject distance, within the system's range. Combined with the electronic flash and fully automatic metering, the Pronto SE required essentially no user input beyond framing.

The Pronto SE's market life was short. By the late 1970s Polaroid was transitioning toward its 600-film platform, which offered a higher-ISO emulsion better suited to the small fixed-aperture lenses used in affordable cameras. Cameras in the 600 series eventually superseded the SX-70-format rigid cameras. The Pronto line was wound down as the 600 OneStep and Sun cameras took over the mass-market segment in the early 1980s.

Why It Matters

The Pronto SE is a useful case study in technology trickle-down. Sonar autofocus was introduced as a premium differentiator on the SX-70 Sonar; within the same model year (1977), Polaroid had it in a budget plastic camera. This rapid democratisation of the sonar system was characteristic of Polaroid's strategy: use the flagship to establish a technology, then drive it into the mass market quickly to recoup R&D costs over a broader base.

For contemporary users, the Pronto SE offers sonar autofocus at a fraction of the cost of an SX-70 Sonar. The trade-off is optical quality: the SX-70's glass optics and larger lens opening produce noticeably sharper results than the Pronto's modest plastic lens. But for social-snapshot and experimental shooting, the Pronto SE's convenience is hard to fault.

Sample Photographers / Notable Use

• The Pronto SE and similar sonar-equipped consumer cameras were used in school and family photography through the late 1970s, where the autofocus removed the most common cause of failed shots.
• Polaroid's advertising for the Pronto series in 1977-1978 emphasised foolproof operation, targeting first-time camera buyers in the US mass market.
• Contemporary instant film enthusiasts occasionally use the Pronto SE as an affordable entry to sonar autofocus shooting, favouring it over the more expensive SX-70 Sonar when optical quality is less critical than ease of use.
