Based on the Infidex 716 camera's helicoid using the Mamiya C330's taking lens this produces gorgeous 645 medium format film photos while being interchangeable with the Infidex 716 camera so you can also take panoramas on 35mm. No darkslide so don't change lenses in the middle of a roll. This took a couple iterations to get right. This can be printed in PLA or ASA, I recommend ASA if you plan on taking it with you on trips since it is a more robust material.
