Polaroid SX-70 Land One Step Sonar Camera. Though Polaroid had considered a. Designed SLR for its Colorpack film, the SX-70 was the first. SLR and the first camera to use Polaroid’s new SX-70 integral print film, which developed automatically in broad daylight without the need for intervention from the photographer. The SX-70 was also notable for its elegant folding design, which allowed the camera to be compact enough to fit a man’s suit-jacket pocket when collapsed. There were a variety of models beginning in 1972 with the original SX-70, though all shared the same basic design. (the user was expected to be able to see the difference between in- and out-of focus) because Dr. Land wanted to encourage photographers to think they were looking at the subject, rather than through a viewfinder. When many users complained that focusing was difficult, especially in dim light, a split-image rangefinder prism was added. This feature is standard on all later manual focus models. The later Sonar OneStep and SLR 680 models were equipped with a. System, which permitted returning to the plain focusing screen. The Sonar Onestep models were the first autofocus SLRs available to consumers. Polaroid Corporation marketed this relatively inexpensive, novel sonar technology as a set of components to hobbyists in order for them to incorporate distance sensing into other systems. The later SLR 680/690 models updated the basic design of the Sonar Onestep to more modern standards by incorporating support for newer 600 cartridges instead of SX-70 cartridges, and a built-in flash instead of the disposable Flashbar. Today they are the most evolved forms of the SX-70, and are highly sought after by Polaroid enthusiasts. Though expensive, the SX-70 was popular in the 1970s and retains a cult following today. The SX-70 included many sophisticated design elements. A collapsible SLR required a complex light path for the viewfinder, with three mirrors including one. Of unusual, aspheric shapes set at odd angles to create erect images both in the viewfinder and on the film. Many mechanical parts were precision plastic moldings. The body was glass-filled. A very rigid plastic which could be plated with genuine copper-nickel-chromium. Models 2 & 3 would switch to the less-expensive and more-easily cracked. In either Ebony or Ivory color. The film pack contained a flat, 6-volt “PolaPulse” battery to power the camera electronics, drive motor and flash. The original flash system, a disposable Flash Bar. Of 10 bulbs from General Electric, used logic circuits to detect and fire the next unused flash. The original SX-70 was a high-end consumer market camera, with a folding body finished in brushed chrome and genuine leather panels. Polaroid SX-70 film was introduced to the market in 1972, and was a market success despite some problems with the batteries on early film packs. The original SX-70 film was improved once in the mid-’70s New Improved Faster Developing! And replaced in 1980 by the further advanced “SX-70 Time-Zero Supercolor” product, in which the layers in the film pack were altered to allow a much faster development time (hence the “time zero”). It also had richer, brighter colors than the original 1972 product. There were also professional market varieties of the SX-70 film including 778 (Time Zero equivalent) and the similar 708, Time Zero film without a battery, intended for use in applications such as the “Face Place” photo booth and professional or laboratory film-backs, where a battery is not needed. Time Zero was the film manufactured up until 2005, though overseas-market and some last run film packs were marked only as SX-70. A feature of the SX-70 film packs was a built-in battery to power the camera motors and exposure control, ensuring that the battery would never be exhausted as long as film was in the camera. The “Polapulse” battery was configured as a 6 volt thin flat battery, and used zinc-chloride chemistry to provide for the high pulse demand of the camera motors. Polaroid later released development kits to allow the Polapulse battery to be used in non-photographic applications.
