This
camera is a revised and upgraded SX70. It uses 600 film, so shorter
shutter speeds and smaller apertures are possible. It can also use
i-Type Film with the help of an external battery. After Polaroid went
bust, several firms specialized in SX70 repair. Mint, a Hong Kong based
firm and one of the best known, began repairing SX70 cameras some 20
years ago. They offered also upgrades. These cameras are all from the
70s and 80s. In spite of their good build quality, they age.
So Mint then offered new, upgraded electronics for the use of their
time machine, a device that makes it possible to set exposure times
manually. Up to now (2023) the time machine sets the aperture to F8,
smaller apertures are not possible. Bear this in mind if you want one,
they are quite expensive.
There is a whole
community on the web about SX70 repair and electronics, the most known
is OpenSX70. There are also forums which can advise and members that
help with repair. My camera was revised and upgraded by pola.reck, an
Italien repair man. As
the SX70 is
a good camera and a real SLR, prices are still quite high. Prefer a
revised camera, the photo cell gets dirty with time and exposure may
not be good. Beware of
the Model 3, this isn't a SLR, so don't pay a lot of money for it.
In my opinion Polaroid film
made a big step forward in 2023. The colours are bright now, the photos
look sharp and contrasty. Development times are shorter, at room
temperature the photo is ready after 10 minutes and it has no longer to
be protected from light after ejection, although it is still better to put it face
down or into your pocket and keep it warm for the first 10 minutes. I
think the new film is quality wise as good as the famous Time Zero
film, it just takes a bit longer to develop. So prefer film made after
mid-2023. And yes, a good camera makes sense again, even if it is more
expensive.

Some photos:
Camera closed.
It has no tripod socket.
Camera open. Right side and front.
Front. A model 2 with split-screen focus point.
Left side. The camera has a socket for an electric remote control.
Back. It has no strap lugs.
A USB socket to connect an external battery for the use of i-Type film,
which has no battery. There is a Mint model with an internal battery.
As there is no room for a battery in the original housing, Mint built a
new housing which is about 5mm thicker and has a USB socket for
charging. An elegant solution at very high costs.
The camera and an external battery, connected via USB-C. Works fine, so
you can really use i-type film or packs with a weak battery.
A 5000mAh would be sufficient.
A very common USB-C connection. If you are inside, you can connect the cable to a charger as well.
As the Model 2 has no tripod socket, I will look for an adapter and perhaps fix the battery to the adapter.
