It's pretty well known that you can use certain Fuji films in Polaroid cameras. But the question is, does it work the other way around?
Well, I ran out of film for my Fuji Instax Mini recently. I knew that Target sold the Polaroid 300 that looks just like the Mini 7s and that they also carried the film for it. So, I picked up a pack to test.
The cartridges look exactly the same. The film does too (Fuji on the left and Polaroid on the right). I've taken several shots with the Polaroid film, and I'll definitely be picking up more on my next Target run.
