Polaroid SX-70 Land Camera Sonar OneStep

All too often, the word "instant" is conflated with the word "bad."  In the world of eggs, coffee, and soup, that conflation may be warranted.  In photography, however, "instant" does not carry that connotation.  This is largely thanks to the work of one, Edwin Land, who revolutionized the world of photography with his "self developing" film and the release of his Land Camera in the 1940s. 

After years of improvements and refinements, the Polaroid SX-70 Land Camera quickly established itself as the flagship Polaroid camera.  Introduced in 1972, this single lens reflex (SLR) camera provided photographers with a true view of their composition, which was not available with any of the other Polaroid cameras.

The Polaroid SX-70 Sonar OneStep shared the same basic design as the other collapsible SX-70s.  It came with the standard 114mm f/8, four element lens of the SX-70s; along with the 77mm square image.  The resulting image is roughly equivalent to using a 45mm focal length lens on a standard 35mm film camera.

What set the Polaroid SX-70 Sonar OneStep apart from its other SX-70 cousins is that it used sonar for determining focus distance.  With the addition of an auto-focus motor in the camera, the Polaroid SX-70 Sonar OneStep became the go-to SX-70 for photographers who wanted a premier instant film camera without the stigma of whatever makes up an instant omelet.
