Jim ... (iirc) I think the BASE ISO for the Kodak is 160 ... and does go down to ISO 6.
... it uses some form of interpolation of multiple exposures (pre-HDR) in camera to achieve the 'super-low' ISO's (somebody please correct me on this).
The only literature I've seen on it makes reference to CMOS, but is worded in such a way that I'm still wondering if they are talking about some form of architecture, rather than the sensor itself ... hence, still wondering if it is actually a CCD sensor. CCD's are SLOW ... and the Kodak is definitely SLOW by comparison to CMOS sensor based bodies.
