This camera is probably for affluent eccentrics. I like it enormously. It's expensive but you should save money by buying the lenses used, for example from KEH. Be sure to read the instruction manual for the camera before buying your M series lens. Certain ones won't work.
Walker Evans observed that "color is vulgar." I agree with that . This camera does not record color info and thus gives you an immense gray scale as compensation. Too bad Ansel didn't live to own one. I suspect he'd give it 5 stars too.
I especially like how inconspicuous it looks-- it doesn't scream Leica--and it's small. You can blend into the masses and pretend you're Cartier-Bresson.
