It has a Foveon sensor, essentially 3 16MP sensors stacked for each Red-Green-Blue primaries. Although it is better at color resolution since there is no interpolation, the spatial resolution is still 16MP.

Yeah, and did you see that they are issuing points to those who paid the original price for the camera?? It's a good move on Sigma's part, now let's watch closely what PRIC comes up with over the next 12-18 months. It's going to be interesting...

I am interested in the Foveon technology. We may find that it has more potential than the Bayer sensor(or not), but the Bayer is a proven technology that has been through many many cycles and many manufacturers are working to improve it. At what point does the new idea become superior to the tried and true product. Look at electric vehicles vs combustion cars. Electric cars are the future, but combustion cars, with decades of refinement and established infrastructure are more usable for now.

If these become mainstream I hope they enlarge the sensor.

It's still a full frame for 2300, that's awesome no matter how you cut the cake. And consider that the Foveon is supposed to get really sharp images because of how the sensor works

The physical sensor size is APS-C, not full-frame. Basically this camera is the same exact thing as their normal SD1, but they finally decided to sell it at a somewhat more reasonable price.

I got that email too. At the site under SPECS -- Image Sensor Size: 23.5mm x 15.7mm -- which is a bit less than the nominal APS-C size of 25.1mm x 16.7mm and very close to my K20D's sensor sized 23.4mm x 15.6mm. In other words, ain't no big thang.

Fuji S5 pro did a simlar thing. It was advertised as being 12million pixel but it produced 6million pixel files.
In the fuji they used 6million very large pixels which works great in low light detail and 6million small pixels which gathered more highlight info.
Its a good impresive system that gave great dynamic range and film like quality pics.
Hence it came very popular for weddings. Its a shame they seem to have dropped this approach as it worked well.
I would have loved it if they did another with a true 12million pixel each.
