I'll believe it when I see it - and if it does materialise - and accept M lenses; it will NOT be a budget item.
I'm thinking M9 price minimum, and if limited edition, quite a bit more.

LOL this will thrill the Leica fans ;-)

Wait a minute, I always thought the best B&W conversions are the ones that have colour information in the RAW?

As Brian stated, a sensor is a monochrome device, it is sensitive to light level only. The colour information is added by either the Bayer filter, or in the case of the Foveon the depth to which various wavelengths of light, i.e. different colours penetrate the silicon. Therefore the camera has added the colour information to the image. The uncoloured information must by inference be the truest representation of the light levels of the original scene.

Well that's my understanding for what it's worth.

hmmm ok thanks for explaining that.

No- the best Monochrome images are done with a Monochrome sensor, whether electronic or chemical based. Otherwise, Kodacolor 400 would have put tri-X out of production decades ago. Filtering, also best done optically rather than digitally.

That way you do not have to maintain two code trees and test procedures. That is the hard part of having different versions of a camera. Otherwise, a Monochrome sensor is just like ordering a Bacon, Lettuce, and Tomato sandwich without the mayo. Leave out the color dye, have the firmware skip color interpolation, everything else stays the same.

I'm not sure whether I'm nitpicking, or simply not understanding a couple of things:
Black and white film (whether silver- or dye-based) doesn't have equal sensitivity to all wavelengths of light (hence pan- and ortho-); How does this play into the discussion?
I "get" that a Bayer filter adds colour, but if the Foveon is sensitive to different wavelengths, is it not recording rather than adding colour?

Hmm, I knew there was a reason why I normally avoid discussions such as this Paul, I would suggest that you are correct about the Foveon sensor.

The Foveon sensor has separate layers for RGB. The RGB Dye still absorbs most of the light that passes through the detector array.
"Brian's world": For improved Monochrome Dynamic Range, I would use Neutral Density filters on the Foveon sensor so that each layer captures a different level of intensity, then add the layers. Preserve more highlights and shadow detail.
