SIGMA VIDEO CAMERA W/ FOVEON X75v....Tomorrow the official announcement will be their on D P Reviews

This new Foveon sensor is based on X3 technology and records 3 levels
of colour like movie film. 3 chips will not be needed to give the same
quality as a 3 chip high end Sony. Look for the announcement tomorrow.

Gee George, does that mean you'll be spamming the NG with more garbage under
yet another screen name?

And just like the other Smegma crap, something to avoid.

It would be so very nice if you stopped posting to rec.photo.equipment.35mm

At least until such time when foveon starts making 35mm film.

So ... now you have learned the skill of cross posting.
How very clever of you Mr Preddy.

BTW - movie film does not have three layers with colocated
color sensors. It is more like a Bayer one with the sensing
elements (grains) not colocated. And ... sometimes it is
more than three layers. And the layers do record rather clean
colors, not like the Foveon crap where all layers are a
variant of monochrome layers, slightly filtered.

I wouldn't be surprised if the current 3.43MP X3 records 3 levels of
blue and green, blurs the hue, and gets the luminance directly from the
red channel, because that's what the images look like.

The precise spectral response of the 10M is published all over the
web, same for the 5M.

That is exactly why the Foveon Pro 10M used in the SIgma SD9 and SD10
are also used for exacting scientific applications like the above,
while Bayers never are as the data they present is 75% made up during
interpolatative color processing. That's right, every pixel color in
every Bayer image is 75% guessed, while 100% of every pixel color in a
Foveon image was measured with perfect quantum accuracy precisely as
presented, much like the time keeping accuracy of an atomic
clock--absolutely perfect, all the time.

How do you keep a straight face with this bull****?

Which indicates that e.g. green (550 nm wavelength) is seen as 49% blue,
63%green, and 45% red. That means the color is VERY desaturated and massive
postprocessing is needed to get a usable color (but with lots of noise).
The above implementation is also only 30-bits digital color output!

LOL. 9-bit colour 8-) a whopping 128 different colours! excellent match to
the colour screen of your first-gen colour screen mobile phone.
