Polaroid has many interesting interesting stories, which also includes suing Kodak and winning, and developing instant movies, which destroyed them.
The SX-70 is their biggest victory.
A folding, single lens reflex camera.
"Instant" Polaroid film in a pack which included the battery for operating the camera and moving the film.
Through the lens metering, which included the flash.
This is a later model with the ultrasonic auto-focus, which turned up in many other uses.



And using the same film pack:
Polaroid Macro 5
Crazy technical plastic was originally for medical and police ultra macro closeups.
Ah, what stories it could tell.



I picked it out of the FREE box at a garage sale.
