Polaroid 640 instant film camera (serial F1Z93529NB)

The Polaroid 640 is a simple, elegant Polaroid 600 series film compatible camera from the 1980s. It was tested with a film pack and works very well (it's extremely easy to use). 

This is a very simple fixed-focus instant camera so for sharp indoor photos, your subject should ideally be from 4 to 10 feet away. For outdoor photos in good light, anything beyond 4 feet (1.2m) should be in focus.
