Also if the Pixel size is smaller than the wave length of light that one is attempting to captured, you'll miss an awful lot of light in that wavelength. (I'm not sure how perverse the universe is, I'm betting on maximum amount of perversity here, in that if what will benefit more one more in

Larry, I've had that hypothesis (in the back of my mind) for a while. Your question made me thinking in more detail about it. On one hand the argument for why that should be possible is as follows: If the noise is due to the statistical uncertainty (Sqrt(N)) for the number of counts (N) on th

Do you mean like two full-frame models with different Mpx count sensors? What sensors would be available for Ricoh to use for new Pentax DSLR cameras? I'm thinking the 42Mpx Sony sensor was chosen because Sony was willing to sell it to Ricoh in the quantities Ricoh wants for the projected Pentax

Collin, my understanding that all cameras from K10D through K-5 (K20D, K-7) are supporting some basic PZ operations such as lens retract when camera is turned off. However, it also seems to me that this is where it ends. None of the modern cameras fully support PZ (zoom tracking, etc). So, it c
