Convert your Polaroid to 120 roll film and enjoy it

Minh Nguyen , Oct 10, 2007; 01:04 a.m.

Many Polaroid lovers e-mail me about converting a Polaroid to MF roll film and I decide to post it up to offer them a start-point. But be careful you do it yourself and safety first.
1) Drill a 1/4 inch hole at the right film chamber, get a 1/4 inch bolt, 1 1/2 inches long make a winding shaft by grinding to made it tip fit the hole of 120 roll film, get a 1/4 inch knob from home depot or surplus store, make an adapter by two ends from the old roll film.
2) At the left chamber make a film holder bracket or just shim both side to prevent the roll film bouncing.
3) Drill a 7/16 hole in the pressure plate and cover by a clear red plastic or glass.
4) Prevent light leak from the back by black cloth or velvet..., very careful. I still make mistake some time but better now.

You can make masks for different formats. Here are some pictures of the Polaroids and some taken by Polaroids in 6x12 format

I have done this exact mod to mine and it works very well. I did some research before I modified mine and other people were drilling through the top for the winder which makes no sense at all. I have a label on the bottom of mine which gives the amount of rotation needed between frames.

I used the spool holding mechanism from a defunct Agfa Isolette for the supply spool.

6 x 12 is a bit optimistic. It's closer to 6 x 10 - but still worth doing though.

Nice work, great pictures ! What I want to see though is someone converting an SX-70 to 120 roll film :-) I reckon there's jussst enough space in a 600 film pack for a roll of film if the battery was taken out and the camera powered externally.

What model Polaroid are you working with?

Luis Triguez , Oct 10, 2007; 01:55 p.m.

Well done Minh!

Patrick Dempsey , Oct 10, 2007; 03:26 p.m.

Eddie... this conversion will work with pretty much ANY of the roll-film Polaroid cameras except the Model 80... it CAN be done to the Model 80 as well but that requires some grinding of rivets down in the body. Just to encourage more...

This is a crop from a 6x12cm neg... probably about a 5x6cm section. This is from a Model 150. It also looks really cool when its strapped to your side... sorta reminds me of the scientific equipment Mr. Spock used to carry on away missions... Mr. Spock I aint:

Who is that handsome guy ?

Thanks for looking at this gentlemen. Minh

I have a PL 250 that works fine with PL pack film. PL Film is really too expensive. Can that model be converted and how do we bypass the exposure meter or do we just use 120 film that is ISO campatable like 100 ISO and simply use the internal metering system? I'm guessing that's a good way to go. This sound very interesting.

Patrick, your photos are wonderful.

Minh, thank you.
