PopPhoto reviewed the Sigma SD14, one that equipped with a second-generation Foveon X3 sensor, which has a 1.7X lens factor, boasts 14.1 megapixels, and is promoted as a color-accurate, detail-obsessed, low-noise alternative to the CMOS and CCD sensors used in other DSLRs. Here’s the conclusion from the article: “Our image quality tests came down in favor of RAW files over JPEGs. In JPEG mode at ISO 100, the SD14 captures detail on par with an 8MP DSLR such as the Canon EOS Digital Rebel XT. Combined with an Extremely High color accuracy (9.9 Delta E), JPEGs earn an Extremely High image quality rating.

But in RAW, also at ISO 100, the SD14 performs more like a good 10MP DSLR, capturing about 10 percent higher resolution and Excellent color, earning it an Excellent image quality rating. Still, NEF RAW files from the $920 (street) 10.2MP Nikon D80 show higher detail. So this is not what you’d expect from a camera billed as having 14.1 megapixels.

…Apparently, the SD14’s internal image processor has a hard time converting high-ISO RAW data into JPEG form, while the supplied computer software handles the job more efficiently. The image processor also takes a glacial 8 to 10 sec to clear the buffer for another shot after a burst sequence of up to a mere six frames at 3 fps. That’s not even in the same ballpark as the burst rate and capacity of competitive DSLRs.

In all, the camera handles well, opens creative doors with IR, and is technologically unique. But the promise of 14.1MP doesn’t pay off. And given what you can find in today’s DSLR market for $1,600, we see the virtue in shopping around.”
