This is the POLAROID One600Pro,
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: probably F12.9/100mm (2-element plastic), there is little information about it. Autofocus, down to 60 cm (2 feet), some models 45cm (1.5 feet), shown here, distance inscribed around the lens. Shutter: 1/3 - 1/200 s Size: approx. 9x12x15cm, Weight: 495gr. Automatic flash with quick charge, flash always fires. Self timer. Tripod socket.
