The point of using such a pitifully small piece of film from my view is always having a camera with me. While I would never be able to produce poster-sized prints, relatively sharp 4x5 prints are possible. Even a Leica ltm camera is bulky and heavy in a pants pocket for every day walking around. Minolta 16 and Minox take up little space and are reliable viewfinder cameras. I don’t see the advantage of a bulky SLR that takes a pitifully small piece of film. My next step up in portability is an Olympus XA. Minox 35s are just too unreliable. None of the above are meant to replace 35mm, MF, etc. just handy to have around.
