Sure I believe it. Stefan Daniel suggested the possibility of a B&W-only Leica digital camera at a LHSA meeting a few years back.

... I'm positive that a b&w only digital camera would be a huge hit, and I would bet that not only Leica could market such a camera sell, but also Fuji and Olympus with their mirrorless cameras.
You do know we are talking of Leica right? This camera, if made, will be $8000+.
Define "huge."
I don't doubt that a lot of people in this forum (as well as some like-minded folks) would like the idea of a B&W camera. But 90 percent of that interest in going to drain away when we see an $8,000+ pricetag.
Really, we are talking about a niche within a niche.
I'm not even sure I'd be interested - and 90 percent of what I do is B&W. I'd just have to see real compelling evidence that this B&W-only sensor would be a marked improvement over what I get from my color sensor.
Bob,
My understanding might be wrong, but I understand it takes three pixels to make a color signal and the required filtering for color processing degrades the signal.
At home I have single ended triode monoblocks using a 300B vacuum tube for a stereo. Signal processing is a big factor. I'm assuming that signal processing in a B&W only sensor would be simple and more pure in a similar analog way to my audio where less is more.
Your explaination about sensitivity makes sense. and there's a lot of grey area that I'm hoping leads to other possibilities.
As I remember Phase One did a comparision between their B&W sensor and one of their much larger color sensors to compare remarkable resolution and make a statement about the jump in resolution. This lead me to believe that there is a possibility that making a more basic B&W only digital camera might have some real performance advantages.
Any help in further understand is greatly appreciated. I'm just an old film guy who doesn't even scan.

Don't see a point as digital is basically just good for color.
Well I thought if there would be no LCD the could save a lot on making it, dont know about making a B&W sensor though, maybe that is very expensive.
If it will be 8000+ the image quality has to be something that has never been seen before, a camera with limitations like b&w only and no LCD cant be priced this high.
Tell that to Salgado.

Salgado is still using a 4x5 internegative..
Cal,
Below are two typical applications of a 16MP CCD sensor ; one is monochromatic and the other one color, both are the same sensor made by Kodak, same overall dimensions, same pixel count and as you note the same (!) dynamic ranges too. What differs? Only the sensitivity: One is 0.1 lux @f1.4 (color) and the other one 0.01 lux (monochromatic). If you add the R,G and B curves on the Quantum Efficiency plot graphically you will end up more or less with a similar looking but somewhat lower efficiency curve of the Monochromatic Quantum Efficiency + some IR portion away from the visible light due to (almost) no filter layer on the monochromatic sensor. Further, removing the CFA (color filter array) without pixel binning may lead only to comperatively lower sensitivity compared to the one with CFA which would not be desired by Leica (or any other sensor user), especially these days while even the APS-C sensors are claiming perfectly usable ISO-6400. (See the new XP1, setting a standard for IQ! Yes, just pray that Leica would catch up with the rest of industry, at least for B&W..)
As for signal processing: I hope and wish Leica could come up with an excellent OOC jpeg capability to provide some convenience for the users.. How Fujifilm succeeded with such state-of-art in camera processing to deliver examplary OOC color photos with film simulation! Leica is supposed to do the same for a much simpler B&W processing this time. 🙄

(BTW, I too listen to single-ended triodes, I am 11 years of your senior and am still developing my own films since 50 years..🙂 )
It's very plausible. The only Leica affienados who have not yet switched to Digital are the die hard B&W film shooters. Combine that with the fact that (at least in my perception) the majority of M8 & M9 pictures posted on the web are B&W converted.
So it makes A LOT OF SENSE to target the B&W market IF they have a spectacular product at hand.
There is also the possibility of crosselling the B&W only camera giving their wealthy customerbase.
So it al depends on how good the B&W only camera is compared to B&W film. And how much better it is compared to a converted digital file from the M9.
It would be an exciting camera, although i doubt it can substitute B&W film for me personally.
Well I thought if there would be no LCD the could save a lot on making it, dont know about making a B&W sensor though, maybe that is very expensive.
I heard rumors that the Leica announcement will be about a Leica M-wet plate collodion version. Insider information, couldn't get confirmation, but very interesting indeed if true.
