This is the POLAROID 660 Sun . It is one of the better Polaroid models from the
"square corner" series, marketed just under the number or as "Sun" and "OneStep",
this one has Autofocus via a Sonar system. The Autofocus can be
disabled (for photographing through a window-pane e.g.). The
disable-switch is under the flash and has to be held while
photographing.
To save the battery the flash only charges when
the shutter button is pressed half way down. It charges quickly, but
you loose some seconds as the camera will not shoot until it's
charged. There is a red light in the viewer while the flash is charging. It has nevertheless a 2-part shutter button like
the Lightmixer, which enables you to not fire the flash if you only
push the second part of the button and not the first (red) one.
