However, the Fuji packfilm is slightly different from the Polaroid film as it is made from plastic and not metal. This becomes an issue with the folding Polaroid Land Cameras that use this film, as there is a big spring inside the camera that was used to keep pressure on the pack. On the old Polaroid packs the metal pack could spread the pressure from this spring. The plastic Fuji packs can't do this and the film jams when you try to pull it out and most likely end up tearing the paper tab. Removing this spring fixes this issue.
The electric shutter and if available the electric print timer in these cameras uses either 1 or 2 unusual sized batteries. Again, the batteries are hard to get hold of and expensive. Adding a AAA battery holder means you can use easily available batteries for your camera.
In this example, I am using a 3V Polaroid 350 Land Camera.
