If you get yourself a Polaroid 120, to shoot Fuji Instax Wide film, you need to get yourself one of these Belair 612 instant backs.
This is pretty trivial. Everywhere you look online, they will teach you the same thing.
What they don’t tell you is what to do with the back…
Take the metal plate with INSTANT BACK printed on the corner to expose three screws.
Unscrew and remove. You’ll get to here. To get to the other end of the wire, remove more screws.
Then you get here. You’ll see the rollers. Be very gentle around the roller housing, the counter gears and that extraction lever thing.
remove the rubber plug from the crank handle. You’ll see the yellowish foam above. there’s a Philips head screw underneath there. Unscrew it with a screwdriver. Nevermind the foam. You can crush it.
The handle comes off .
Unscrew some more and the back with the cover door comes off. You need that off to get to some other screws… I forgot what though, but it is an unavoidable step. The picture above shows the back (to the right of the picture) already off. I’m taking off the bottom piece that’s towards the front that will eventually get in your way of mounting the back.. and you expose some stegosaurus blade like shapes underneath …
This is the guts. note the springs holding the rollers in place. those are *very important* and are anchored to some very weak looking plastic. Be very gentle and careful with those.
The back cover and hinged door thingy that you had separated from the *guts*
You can put the back cover back onto the *guts* part. See the stegosaurus blades i’m talking about. Those will come off..
You want the back *flat* against the back of the Polaroid 120. Hack off anything that’s sticking out. Add material to anywhere that caved in. See the stegosaurus blades gone, and the top ridge now rests on the white plastic strips. if you note the top right, you’ll see that I’ve hacked some of the corner sticking out off.
