The Polaroid SX-70 is one of the most famous instant cameras in the world. It was the first instant SLR camera ever made, and the first to use Polaroid’s now-iconic instant film which brought photos to life the moment they left the camera. Its manual controls have made it the go-to camera for artists and dreamers alike, and its fold-down design means you can take it with you, wherever you go. This version was released 1978 a few years after the original SX-70, and features Polaroid's patented Sonar Autofocus, so you can make perfectly-focused instant photos every time. The camera was produced for 8 years until 1986 and used the 778 film packs. Film for the camera has had an off and on production affair with various companies but can still be purchased for the SX-70 averaging $20.00 for 8 exposures. This camera has a sonar autofocus system that greatly helps the user's ability to focus the camera, especially in dark environments, and it can be turned off if manual focus is needed. The lens is a 4-element 116 mm f/8 glass lens, and the camera has an automatic exposure system. You can focus the SX-70 as close as 10.4 inches (26.4 cm), and have a shutter speed range from 1/175 of a second to more than 10 seconds. A whole array of accessories can be utilized with SX-70 cameras, such as a close-up lens (1:1 @ 5 inches), electrical remote shutter release, tripod mount and an Ever-Ready carrying case that hung from the neck and unfolded in concert with the camera.
