This is the POLAROID One600,
a foldable camera for 600 film. The One600 series is smaller and
lighter as the the usual cameras and comes with a wider lens (100mm vs.
116mm). It's the last series built before the company went bust. In my
opinion the One600 series is underestimated, it's easy to carry around,
the built-in strap is very handy.
Lens: F12.9/100mm (2(?)-element plastic), focus free. There is little information about this. Shutter: 1/3 - 1/200 s Size: approx. 9x12x15cm, Weight: 495gr. Automatic flash with quick charge, flash off possible on this model. Tripod socket.
