The reason the Fuji isn't 6M pixels is because the sensor isn't a 6M pixel
sensor!  It's a 4.3M pixel sensor, interpolated to make 6M pixels.

<snip> I believe you missed my point.  You need contrast...ANY contrast to
distinguish two lines.  It is the amount of contrast that will vary
depending on how far the two line "tones" are apart.  It obviously depends
on what you are comparing to what.  If you compare Zone III with Zone IV,
you have substantially reduced contrast, but that does not make it less
resolution, just less contrast.  If you compare Zone III with Zone X, you
have higher contrast, and not necessarily higher resolution.
