a B&W digital camera would be really, really stupid, Canon!

NOT done - roughly 75% loss of photons due to color filters in bayer array.
Really? Seriously?!? See, I wasn't really sure why but I just knew there had to be some reason I bought a couple of $14,000 Zeiss AxioCam HRc color cameras for brightfield microscopy, and a couple of $14,000 Zeiss AxioCam HRm monochrome cameras for fluorescence microscopy where sensitivity for low intensity signals is critical. Thanks for edumacating me!

In that case, why not start up a crowd funded operation to produce one, its so easy.
If there were even half a million buyers, smaller camera companies would be all over it. Even 100,000 units!
There were about 5.8 million DSLR's shipped from Jan - Sept of 2016. How many millions of those would have been sold if they did not have color? Certainly not 20%.

Don Haines said:Ok... Seriously..... can you explain to me why I am wrong?
A normal colour camera has a bayer filter.

I'd certainly be very interested...

Like just about everything else, it's a trade-off....unfocused said:I'm just curious, doesn't having three color channels have some advantages? Pick the channel you want to emphasize and adjust accordingly. Probably couldn't do that with a single monochrome channel.
danski0224 said:Anything with a Foveon sensor will give you monochrome capabilities and no resolution loss due to a Bayer filter.
Something from the Merrill or Quattro sensor generations are most current. There are differences.
The Merrill SD1M and current production SDQ mirrorless have a removable "hot mirror" that opens the door to IR photography.
One is limited to either Sigma lenses or M42 for easy adaptation.
A single well exposed image from either of those sensors will give a 50mp 35mm format camera a run for its money.

jolyonralph said:Except that the Foevon sensors, including the one in the Quattro, have a poor reputation for noise.

I looked that up: http://www.dspguide.com/ch25/1.htm
I won't pretend to understand all of it, but the first two sentences make sense.
A Foveon sensor does not have any interpolation like a Bayer sensor. This is critical along things like high contrast edges.
A Foveon sensor will resolve more detail.
A "50mp" Bayer sensor really only has either 16.6mp (50/3- RGB) or 12.5mp (50/4- RGGB) of image data, and these sensors are in 35mm format cameras. The Merrill generation is 46mp using Bayer math and it is APS-C.
