Here comes a digital-camera chip that could change everything...

The Foveon chip has a *lot* of promise, but it's still up for grabs whether it will beat traditional CCD/CMOS chips. The new Sigma SLR with the chip has beautiful image quality and amazing resolution for the sensor size, but it also has some noise problems, poor low-light performance, some strange artifacts, and somewhat diminished dynamic range. It'll be real interesting to see the next generation.

A more informative review about the Sigma SD9 and it's X3 chip can be read at:http://www.dpreview.com/reviews/sigmasd9/

Hmm, certainly looks an interesting technology for the future - but some of the artefacts in over-exposed areas are pretty horrific. Great big solid white disks, and large areas with all the colour sucked out...

If they can sort these things out for version 2, then they could well have a winner. Certainly, they've come up with something worth keeping an eye on.

Cheers - Steve

You have any links on that? I haven't seen any photos with the problems you describe?

The review of the Sigma(which uses the X3 chip) isn't all that glowing on dpreview.com. They compared it to Canon and Nikon cameras, and I think Canon's CMOS sensors had the X3 beat in a few areas, but the X3 did hold up very well. I think CMOS chips are similar to X3 anyway?
