Polaroid Autofocus 660

About a year ago I got this Polaroid instant camera as a gift, just for my collection. I wanted to wait with my posting here until I made some experiences, but even this is long done (see here). It's quite a while now that it is standing on the shelf next to my other two Polaroids (the phenomenal SX-70 and the old Highlander). In comparison, the 660 is very simple. But very consistently it implements the Polaroid principle to help the photographer with hidden use of automatic features achieving great images.
When folded, it is quite compact and with its sturdy plastic body it doesn't put a lot of weight on the scale (700 g incl. FilmPack). Except for the red shutter button on the right side of the camera all the controls disappear under the folded-down flash part. Even the viewfinder remains dark. I call that smart industrial design. The outside camera shape let you imagine the optical path inside the camera including the central mirror.
The Polaroid 660 Autofocus was launched on the market in 1981 together with other (more simple) cameras to give the new 600 film a platform. The cartridge had the same dimensions as the old SX-70 film, but instead of ISO 160 it had ISO 640, which means four times the light sensitivity. Of course by design philosophy no Polaroid camera has a control to adjust the film speed, so "unfortunately" new cameras or a neutral gray filter in front of the old SX-70 were needed. Of course there were hobbyists who converted an old SX-70 to the new film. The new cartridge also had a slightly more powerful battery, which also could power the electronic flash.
The 660 was the first of the 600 series cameras which had Polaroids Sonar AF system on board. It just premiered only a few years earlier on the SX-70 Sonar OneStep, and can be recognized by the golden resonator membrane. However, unlike the SX-70 the Polaroid 660 focuses its plastic lens via novel internal focusing, whereby the focal length varies : from 116 mm at infinity, 107 mm (about 3.9 m focal distance), 105 mm (1.5 m to 3.9 m), 99 mm (0.9 m to 1.5 m) down to 90 mm ​​(0.6 m to 0.9 m). In addition, there is a so-called automatic exposure Light Management System (the slider with the black and white arrow), which controls the shutter between 1/4 and 1/200 s. The flash switches on automatically in low light and can not be switched off, of course. Unfortunately, flash doesn't work anymore with my copy. For anybody interested, here is a little more about Polaroid's history.
