I own 2 of the original Foveon prism cameras. I have also tested the Sigma 
SD-9 (SD-10 will be even better) with the X3 sensor, which as a consultant, I 
pushed them hard to develop.

I really like the sharpness of the X3 chip and they have managed to match the 
amazing color response of their original prism camera to the point where's 
it's hard to tell them apart side by side, except the X3 is 
sharper.......without Quarter Wave Plate and prisms in the way, plus the 9 micron well site pitch 
is less taxing on the glass than the orinal's 6 micron pitch. Also no anti 
aliasing filter is used on the X3 as the silicon senses full RGB color data at 
every point, just like film (color or B&W). 

The B&W prints I have shown from it have impressed the traditional darkroom 
guys doing only optical printing. They might not be so impressive to the 
advanced crowd here, but then again, they could be.

Contact me off list and I can Email you the file if you wish.
