Sigma claims the SDx are 10.3MP cameras; what do they know? Trying to redefine industry-wide standards to meet the desires of Sigma/Foveon is your best trick, but it's all smoke.

Most desktop models use tri-linear sensor arrays, sometimes in a staggered layout (double lines per color but with half a pixel offset). Bart
From: Keith Jewell on 20 Jun 2005 14:54 (this is to Preddy, but for some reason quoting isn't working at the moment) I know you're a troll ... and you were trolling here about this years ago. But I really want to know: Do you just not get the difference between luma and chroma resolution? The Canon 20D has 8M of luma resolution, and 2M or 4M of chroma resolution depending on the color. The Foveon has 3.4M of luma resolution, and 3.4M of chroma resolution, the same per color. This really is simple. Are you intentionally unable to grasp this? -Keith

Interpolated pixel counts are completely meaningless. Bayers could easily advertise 800% upscaled recorded pixel counts instead of only 400%. In fact, Fuji does do that with the "12MP" S2 "Pro" which only gathers 1.5MP of optical full color data. > upscaling and interpolating are not the same thing. There are 8MP of > data in a 20D image.

Bayers' advertising only interpolated MPs is strictly aimed at a customer base that large doesn't understand anything about digital. Scanner makers tried the same ripoff scam years ago--advertising interpolated resultions instead of optical, but their more computer savvy customer base clobbered them for it instantly--now they know better. Photographers, as a rule, are artists who don't understand digital so they continue to actually enjoy being ripped off--the higher the interpolation degree the more they want the camera. "Give us more and more interpolation", they collectively shout. The DSLR manufacturers, and particularly Fuji, love it--they are taking candy from babies by the boat load.
