Comparison of Sensor Specs - Latest FFs Against Pentaxes

Similar to what I did last time for the 645D, here is an updated comparison with the addition of the latest hot Full Frame cameras from Canon and Nikon (4/5 Nos.) and also the Pentax K-5/K-01 plus the now somewhat old Leica M9, total of 12 models:-

It can be noted that the pixel pitch size has direct relationship with the basic supported ISO range and the expanded span as well, as it is directly related to the primitive noise level of the sensors themselves. Besides, CCD is inferior to CMOS for lower noise higher ISOs, as we all knew.
