In the description of the DP2 Quattro at B&H the resolution already looks very confusing.

Maximum resolution is stated as "5424 x 3616" under "Specifications" . . . but in the "Overview" there is this statement:

"The Sigma dp2 Quattro Digital Camera combines the 29MP Foveon X3 Direct Image Sensor with the TRUE III image processing engine to create high quality images with an equivalent resolution of 39 megapixels due to the unique sensor design. This method uses layers of pixels to capture the color data of the red, green, and blue spectrums vertically, requiring no interpolation. This results in a sharper image with better color gradations."

5424*3616=19,613,148 pixels - that defines the resolution since that defines the spatial sampling.  Of course the Q is not a 29 MP sensor when it comes to resolution since that is defined by 5424x3616 - the spatial sampling - nor does it have an "equivalent (equivalent to what?)" resolution of 39 MP.

B&H is in business to sell cameras.  Look at all of their descriptions of all their products - there is a lot of marketing going on.  However the Q camera has does 29 million detectors.  They have picked up on the market line that Sigma used when advertising the DPXM and SD1M as 45 MP sensors when in reality the sensor resolution is defined by the 15 MP locations counting each of the three detectors at each location.

It's probably best to give it a rest - since this marketing has been going on a long time.  If it sells more cameras - B&H will be happy.
