Polaroid Time Zero SX-70 AutoFocus

1981

Lens -

A later version of the famous SX-70 it is an instant, auto-focus(sonar!) SLR.  Also called the 'OneStep Sonar' it was at one point the best selling camera in the country - due to its cheap price.  Mine is marked 'Model 2 Special Edition' - I haven't been able to a ascertain what sets it apart form the non-Special Edition
(other than the blue instead of red shutter release).
