Polaroid SX-70
The Polaroid SX-70 is an actual SLR camera with manual focus. It was originally introduced in 1972.
The camera uses SX-70 film which has a film speed of 160 ISO. Combined with the f8 aperture it makes this camera mainly usable in bright light. I do have a Mint Flashbar with it, but it's not that powerful so results vary.
Its main party trick is that it folds down to a flat box. Opening the camera usually extracts some oohs and aahs.
Polaroid Impulse AF
The Polaroid Impulse AF has a zone focusing autofocus system where it swaps lenses mounted on a wheel inside the camera depending on the distance it measures with the ultrasonic sensor. Because the sensor is ultrasonic, which means it uses sound waves to measure the distance, it is not possible to focus through windows. The foto's it produces are usually very sharp and with the 600 film which has a film speed of 640 ISO and it's always firing flash it's also good for indoor use.
Lomo’Instant Square Glass
This is a Instax Square camera. It has a manual zone focusing system and a lens that folds out. The photos it produces are great, but in general I don't like the smaller size of the images compared to full size polaroids.
