Don Roberts asks: So where do you classify 127? Just curious. I'd forgotten about 127! http://en.wikipedia.org/wiki/127_film In Australia my recollection was that it was considered a miniature format, a competitor to 35mm. The cameras themselves were probably in part responsible for this attitude, though a 4x6 is so close to 645 as to suggest no difference. Mind you, European books and magazines of the 50's and earlier often refered to 120 as miniature format, 4x5 was medium format then but small, medium and large are kinda subjective. If I go by the standard of what is most commonly used here these days in Oz by the majority, my 35mm is large format. All those 5x4mm sensors make my camera look HUGE! karl
