I have several packs of the discontinued Fuji FP300C, but as it's discontinued I am a bit savy using it. My best camera for utilizing it is the mighty Fuji GX680 which takes 80mm x 80mm images on that instant film. But, this film only increases in price because of availability, and eventually some company would have to start making a replacement for all those nice medium format cameras which use pack FP300C. I believe it's only a question of time with the boom of instant film photography.
Instant film is interesting and would we get an usable negative for scanning, like it was with some type of Polaroid, why wouldn't it be the easiest and most convenient way into film photography.
You can retrieve the negatives from FP300c (and even FP3000b with effort, I think) by using a mild bleach rinse on the discard portion of the peel apart packet.
The remains of my last pack of FP300c are in my Hasselblad Polaroid back. I've been saving the remaining exposures (about six) for something special... Maybe I'll shoot them on TDay (tomorrow).
I sold the rest of my pack film and pack film cameras to another enthusiast, and gave away all my extra Polaroid cameras (four Spectras, One Step+, three SX-70 autofocus cameras) to concentrate on one last original SX-70, the MiNT SLR670a and SLR670m, and a Kickstarter instant that takes Instax SQ. The latest revisions to the Impossible Project films, now Polaroid Originals, have improved dramatically and the Fuji film is quite good.
Then this MiNT InstaKon RF70 (Instax Wide format) came up as being in early development. I sent a note in to them with a check, saying, "I'll take one whenever you get it done." That was a while back, they've just recently gotten enough made to satisfy some of the pre-orders. And it proves to have been worth it.
These first two posts with it I 'scanned' by snapping a photo with my iPhone 8 Plus, but I'll make reference captures with the Leica CL and a more rigorous copy camera setup. That's good enough for me, I don't need negatives anymore. Just good quality captures.
