Sigma Releases Two White Papers; Where’s the SD14?

Foveon X3 compares with Mosaic

While spectators fiddle their fingers for the much-awaited release of the Sigma SD14 digital SLR, the company has published two white papers describing how much better the Foveon X3 image sensor is, compared to conventional systems. (Our star’s not ready yet, Joey, do something to entertain the crowd.)

In essence, Sigma is saying their Foveon X3 is a full-color capture image sensor because it catches red, green and blue light at every pixel location, while the conventional mosaic sensors capture only 25% of the red and blue light and just 50% of the green. Therefore, Sigma says the SD14 will deliver true colors as they really are.

Okay, let’s get on with the main show then. Lift the curtain on the Sigma SD14 and impress the market with its promise.

Earlier, two camera models made similar promises of richer photos by offering innovations with their image sensors: the Fujifilm S5 Pro which appears to be delivering on the promise of its double pixel technology, and the Pentax K10D whose 22-bit ADC still has to deliver on its avowed goal of a higher dynamic range.
