This new product will breathe life into all sorts of old cameras that would otherwise be left to the wayside. Camerhack of Italy has made adaptors for a number of different formats, including 116, 118, 122, 130 and 130 roll film formats.
Even the 1970s hit format, the drop in instamatic 126 catridge has an adapter that will spool modern 35mm film. Note that some 126 cartridge cameras will have issues with the extra sprockets in the 35mm film, while other cameras will be fine. The original format had one sprocket per frame.
