Rebuilt Polaroid SX70 Sonar Autofocus - Updated to use 600 Film Cartridges and New Black Coverings

Sorry, this item has sold.

This is a fully rebuilt SX70 Sonar Autofocus with new black coverings. After rebuilding this Polaroid SX-70 Sonar has had it’s electronics updated for the use of the new faster 600 Style instant film from Polaroid.

The normal SX-70 Sonar uses the SX70 Style film (160 speed), which is fine. But, the 600 film is much faster. The need to use 600 film is why most people move from a SX-70 to the SLR680. The update only impacts the use of the camera without a flash. Working best in well lit areas, indoors and outdoors. When using a flash with this camera, the disposable flash bar are too bright for the 600 speed film so you should use a Mint Electronic Flash at 1/2 power.

The SX-70 Sonar offers a famous package of features:
- You see exactly what your taking a picture of, the view finder looks through the front photo lens
- The sonar auto focus (you can turn it off) will focus on items down to a foot out to infinity.
- The shutter auto adjusts from 1/175 second to 5 seconds
- Auto aperture adjusts from f8 to f22 (you can manually adjust too, which creates fun results with the 600 film)
- Glass lens is 116mm f8, 4 element

A light pressure on the shutter button activates the Sonar Autofocus so you can see what will be in focus in your final print (great for depth photography).

The SX70 Sonar was originally released in 1978 ($250 in 1978 dollars = $1078 in 2022 dollars). It is fun to finally be able to afford the camera that was out of the budget back in the late 70s.
