Claude,

Some tests on dpreview show that the new Fuji sensor has some 
advantages. The 6 MP of the E510 is roughly equivalent to the 7-8 
MP of the more traditional Bayer lay-outs of similar size. That 
Fuji new sensor lay-out is more related to a kind of multi 
sampling than to higher resolution as a result of the lay-out. At 
least that's what I think happens. Signal/noise being better.

I've never seen discussed the relation between 45 degrees 
halftone screens in monochrome printing and the original Fuji 
sensor lay-out.  The 45 d angle of the halftone screen is far 
less "visible" than when the same resolution screen is used at 0 
degree. Same information with less artifacts. For many scenes the 
Fuji sensor should be less prone to moire creation too. That the 
45 degrees angle of the sensor wells isn't there anymore in the 
displayed image is another matter, I wonder whether the eye > 
brain translation isn't in line with the Fuji interpolation 
algorithms to a higher resolution.

Fuji's claims are exaggerated but there's some gain there. I do 
not have Fuji cameras :-)
