If you buy 16mm film get single perforated film as the Minota 16 cameras were designed to use this rather than double perforated film. Although double perf will work in the II model but not later models. Buy only genuine Minota ones. Some years ago there was a guy selling homemade ones that were aweful. You can also slit 120 film for use and there are some unperforated 16 mm microfims.
