Which cameras were the FP-3000B and FP100C films originally made for? Were the Polaroid 100-series the main sales target? I know the -45 versions were intended for 4x5 cameras.

I know people use them on the Polaroid 100-series and also Colorpack, but I've read that the springs in the back need to be modified so as to not dig into the film pack. True?

I'd love to use such a large instant film. My Speed Graphic has a Graflok back, but that needs to be replaced with a Polaroid or Fuji adaptor for FP100C, right?

It is true that the springs in the Polaroid pack-film cameras apply too much pressure to the FP100C and FP3000B film packs. The reason is that the outer case of the Fuji packs are made of plastic where the original Polaroid packs were made of sheet metal. One solution to this problem that has worked well for me is to take the metal back from an old Polaroid pack and use it to replace the same plastic back on the new Fuji pack. Of course you need to have an old Polaroid pack to salvage the metal back from. I've never had a problem making the swap in subdued light.

To use FP100C or FP3000B with the Speed Graphic and Graflok back, you will need either a Polaroid 405 or a Fuji PA-145 holder.

Those films really work great with the Polaroid 100-type pack film cameras (including the flagship 250). Some, not all, of those cameras give excess resistance when you pull the tabs, especially for the first one or two shots in the pack. I've shot Fuji pack film in dozens of Polaroid cameras. Some worked just fine, others were a little stiff, especially the ones that have a development timer in the back.

For cameras that are difficult to pull tabs, just remove the pressure spring from the inside of the back. It takes two minutes and works great. If you don't want to do that, you can open the camera slightly to relieve the pressure when you are pulling tabs, especially for the first two shots. It won't fog the film, though it is awkward.

I've used this technique with my Polaroid Colorpack II. Works fine. Just unsnap the metal latch and allow the camera back to open very slightly when pulling the tabs. It has only been necessary to do this with the first few shots in the pack.

Thank you for the replies.

So which cameras were FP100C and FP3000B originally made for?
