How many people would like Canon to do a monochrome-only body option, similar in concept to the Leica M Monochrom?
I'd certainly be very interested...

Monochrome-only body?

LR had a look at a Leica Monochrom vs. color FF sensor comparison with a 'stump the judges' element to it:

But they somewhat s--- the bed and confounded the comparison by using a higher resolution color sensor.

Interesting, looks like I was on the right path in guessing that you have to factor in the Bayer array effect when looking at higher pixel numbers and resolution. Anyway, the B&W sensor. My understanding is the major "benefit" is being able to use traditional coloured filters, so you'll be looking through yellow or orange or whatever colour your wanting to use for a specific effect.

There wouldn't be much point with a lower-resolution sensor as downsampling would overcome any issues with the bayer filter's conversion to mono - so I'd expect theoretically a 5DSR to be able to generate a 12 megapixel greyscale image that would be every bit as good as a dedicated 12 megapixel monochrome sensor (assuming all else equal.)
But I could imagine a 30 megapixel 5DIV sensor designed for monochrome would be seriously interesting.
I expect it'd also be very popular for deep-sky astronomy (if the UV filter isn't too hard to remove)

Not many. The development cost and low production rate would put the price out of sight.
Canon is geared for high production, they do not know how to produce just a few cameras, their business systems, buying contracts, everything is geared to mass production. Cheaper to buy the Leica. Leica is geared for low production rates.
I've seen companies who excelled at high production rates stumble with low production rates before, its a real thing, and not easy or cheap to overcome.

NOT done - roughly 75% loss of photons due to color filters in bayer array.

I am interested too - just remove the bayer filter (like DonHaines proposed) but just scratching off the filter array from the sensor maybe doesn't work and if, you have to live with a permanent setting in exposure compensation - because the camera firmware doesn't know about the increased sensor sensitivity.

What production issues are there, beside
1. Not adding the Bayer matrix to the sensor? Should be as simple as the difference than that between the 5Ds and 5Ds R.
2. Software modification, e.g. adding a raw format variant, skipping the demosaicing stage, and a gray scale JPEG engine (the standard exists). I guess this part would be harder to implement.

Obviously one would have to adjust the software, but in this case it would consist mainly of removing colour settings from the menus, and as you say, adjusting the software for (roughly) four times the amount of light. The RAW files would also need to be decoded appropriately as well....

There is a difference between a Monochrome ONLY body, and converting a colour image to simulate monochrome. You end up missing all the light that the bayer filter blocked.neuroanatomist said:mb66energy said:neuroanatomist said:

Here, let me make this a bit bigger since maybe you missed the little one.

It's not much different than the difference between the 20D and the small-scale 20Da, 60D and 60Da already produced for astrophotography.
The 20Da was actually quite a revolutionary camera, far more than just a 20D without the UV/IR filter - it also was the first EOS to have live view.
I'm sure the market for a mono body is going to be larger than for astrophotography (and could possibly cover this market too).
And although greyscale jpeg is not a bad option - the camera could record 8-bit lossless greyscale images in PNG format - or even as GIF files!

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!
Now, let's try this again, shall we?

not missed but misinterpreted + size sometimes doesn't matter
