Digital BW, The Print

I too was wondering about the difference in the types of sensors and IR.  My 1Ds makes a very different B&W photograph then my 5D or Nikon D3.  The 1Ds looks more like a typical film B&W then the other two.  The 1Ds produces a grain like look, and the other two don't.

I noticed on the web sights, that the Fuji S3 seemed favored.  Is that because of the type of sensor?  The Fuji Sensor is very different then the Nikon, and Canon sensors.
