And in fact I wrote "all three colour components".

By the way, you should stop your ridicolous crusade against full colour
sensors. The Foveon implementation may have its weaknesses, but there is
no question that capturing the full colour information at each pixel
delivers way superior results.

One day all cameras will use full-colour sensors. Nobody will use Bayer
sensor cameras anymore.

it does not measure any components, it calculates them. if bayer
'guesses' missing data (according to foveon fans), so does foveon. in
fact, foveon guesses much more than bayer does (and is measurably less
accurate).

i have nothing against full colour sensors. what i have a problem with
are the lies from sigma/foveon. some of the stuff they claim is
physically impossible and even contradicts their own patents. deception
doesn't even begin to describe it.

only *if* they don't compromise other more important aspects, such as
resolution, noise, dynamic range, etc.

right now you have a choice between 4.7 megapixels on foveon or 18
megapixels bayer (of similar crop factor). the image quality of the
bayer sensor is so far ahead it's not even funny.

if someone comes up with an 18 megapixel full colour sensor, then it
might be worth a second look.

maybe, but it won't be that soon. physics gets in the way and bayer is
actually very good.

It actually sucks a lot, it's just that you don't know.

right, all those gorgeous images with lots of detail and accurate
colours had me confused.

The loss of resolution is the problem. But you already know this.
