I'm looking for a compact medium format RF. I'd prefer it to be mechanical (but not a deal breaker) and I do not need a meter or interchangeable lenses. Originally, I narrowed it down to these three cameras: -Makina 67 -Bessa III (GF670) -Fuji GS645 But I would perhaps consider these two: -Bronica RF645 -Mamiya 6 I'm not really interested in these cameras: -GA645: I want manual focus -Mamiya 7: I'd rather get a 6 because it is more compact and 6x6 (my preferred format) -Classic Folders: too unergonomic -Fuji 6x7/6x9: too large Well I'm not so concerned about lens quality, lens speed, and negative size but mostly the reliability and useability. -How do these cameras compare in reliability/durability? I like the compactness of the Makina and Fuji GS645 but I fear that they are not that reliable and durable. I plan on "throwing" this camera in my bag without hesitation. -viewfinder/rangefinder: can I assume that they re all good enough? Well I'm really interested in the Makina but I fear that it is too expensive (6x7 and an f2.8 lens commands $$$) so the Fuji GS645 is a good alternative given that I can accept 645 and an f3.4 lens. But then I fear that these cameras are not that reliable so perhaps I should just get a Mamiya 6 since it is probably cheaper than the Makina, more reliable, easier to find, and just more practical at the expense of bulk.
