Originally posted by Na Horuk But! The Medium format cameras are really not that easy to use. They are bigger, heavier, slower and they don't have as many features as current APSC and FF cameras. MF cameras are "bare essentials", but they excel in that.
The next level are view cameras or technical cameras. Even more expensive, even more difficult to use, but they can give stunning results in the right hands. And terrible results in the wrong hands!
Bigger, heavier, slower, yes. But my 645N is maybe the easiest camera to use that I own. The size helps -- the huge viewfinder makes framing shots very easy. The metering is accurate, so put the camera in Av or Tv and it is point and shoot. Not quite a bare-bones camera but pretty close, and that simplicity is part of why the camera is so easy to use.
And I agree about view cameras -- not so easy to use, with many ways to completely ruin the shot.
To the OP's question about the medium format "look", the Pentax 67 with 105/2.4 lens wide open is so popular because it indeed does have a "look" you can't get on small format (without stitching). Taking this even further, this is why the Aero Ektar 7" f/2.5 large-format lens is so coveted.
