Some technical highlights of the the Bronica RF645 system:
Not only does the lenses have built-in motors for self cocking, they also have electromagnetic diaphragms. No other MF RF use that - in fact it's basically unheard of in MF world, and in the smaller format scene Nikon is still playing catchup recently with this advanced feat Canon managed years ago.
The body automatically engage and disengages the dark slide as you dismount/mount the lens. Gone are the ungainly manually cocked dark slides on the Mamiya 6 and 7s that you always forget to disengage after mounting a new lens.
The flash, being hampered by the leaf shutter, is non-TTL. Yet they invented a unique protocol for the dedicated auto flash to communicate with the body for current ISO and aperture setting, basically making the little flash as advanced as a TTL one - just with the meter on the flash instead of behind the lens.
...
The list can go on for another page. The camera itself handles very well and reminds you all the time that it's "sculpted", which I found is just the word for the build quality.
Yet I still sold it. I mean, it feels a bit too advanced. None of these new gadgets got in my way - they are all very fine, intuitive innovations, yet they didn't inspire confidence either. It's not known to be an ultra reliable camera - many RF645 fail on the film advance mechanism as there too was implemented with some cutting edge staff of which the details I could no longer remember...but you know what I mean.
