I've just recieved delivery of a Fuji BYU N-16, the same as a Kalimar Actionshot 16 ( http://shop.lomography.com/actionshot16/ ), but the Japanese market model, with entirely Japanese instructions.
A bit of playing and the aforementioned website has resolved the operation of the main functions, but I'm not sure how, if at all, one sets the film speed. Attached is the only mention I can find of ISO speeds in the manual, is anyone able to translate it for me, or has one themselves and knows these things ?
