hearing about Sigma's SD14 14.1-megapixel DSLR with that nifty Foveon 3-layer image sensor since last year, but it looks like all the hype was just that: Popular Photography got their hands on a review unit and wasn't too impressed. Although the cam earned high marks for color accuracy and image quality, the reviewers didn't see the full potential of the novel image sensor -- JPEG shots were rated on par with the 8-megapixel Canon Digital Rebel XT, while RAW images actually had less detail in them than shots taken by the 10-megapixel Nikon D80. The reviewers also knocked the slow image processor, which they found produced blocky JPEG images at higher ISOs and took 8-10 seconds to clear its buffer after shooting just six pictures in burst mode. Although the Foveon sensor is promising, the review concludes that you're probably better off spending your $1,600 elsewhere -- not exactly a ringing endorsement of the "fundamentally better technology" Sigma and Foveon promised.
