If you happen to have an old SX-70 camera lying around, you're in luck. SX-70 cameras can take Polaroid 600 film with an easy modification. Folding SX-70 cameras are superior to 600 cameras as they have optional neutral density filters, glass lenses and a starting focal length of 10.4 inches. The modification to use 600 film with SX-70 cameras is not a modification to the camera, but to the film cartridge and is simple to do.
