really truly innovative!

it is a very interesting design.

RGB ration is:
1:1:4, instead of former foveon 1:1:1, or Imacon multi-shot, which is 1:2:1

i think the result is less heat dissipation, but higher "real" resolution (in terms of image size).
dunno if the IQ remains the same, or even better than before??!!

Tempting?

I bet the IQ should at least hold the same level as its last generation?

Here is another statement from Sigma...

http://www.sigmaphoto.com/article/sigma-dp-quattro

The newly developed Foveon X3 Quattro is the latest generation of this unique sensor. While retaining the distinctive characteristics of its predecessors, it offers an even higher level of image quality. In addition to 30% higher resolution, the volume of image data has become lighter, and it enables much faster image processing and lower current consumption.

At the same time, Able to maintain the same exacting standard of image quality while increasing megapixels and enhancing noise characteristics, this 1:1:4 solution was the inspiration for the name of the current generation of Foveon sensor: “Quattro.”

The name of "Quattro" made my thinking of the top series of Audi...

希望電子性能正常一點就好了..

The Foveon X3 'Quattro' sensor samples 19.6MP of data at its top layer, but only 4.9MP at the two lower levels, meaning it captures higher luminance resolution than color resolution (something that's also true of conventional 'Bayer' sensors)

I don't know what is the idea behind... why don't simply make all 3 layers to 20MP?

According to optics, the theoretical resolution of a lens depends on the wave-length of the incident light through the lens: the shorter the wave-length, the lower the resolution.  Therefore, it makes sense to increase the no. of pixels in the blue layer of the senors to enhance the senor resolution because blue light has shorter wave-length.

However, I have no interest to have another APS-C camera.

Sorry, I've made a mistake.  It should read: "the longer the wave-lengh, the higher the resolution"
To clarified a bit, the claimed resolution improvement is "luminance resolution" and not "colour resolution" as stated, otherwise Sigma should increase the no. of pixels in the red layer or even the green layer (since red and green light has higher wave-length).

Thanks for the explanation!!
