Helpful practical info, thanks

Just purchased one of these units.takes you back to when you were a kid with your old Polaroid. But with a way better lens

Thanks for sharing. It for sure looks like a steep learning curve getting the exposure to work. I had a mamiya rb67 instax back from a maker on FB (he repurposed an instax square camera) the images were really good at box speed 800) I used color film. The back was $350 i think. unfortunately the wiring job was crap bc a single pack of film and it was toast! It wouldn’t turn on. i sent it back and he fixed it and the same thing happened again. it’s too bad because the images were amazingly sharp! I’m happy your back seems to be a better build.
