From what I understand there are no supply issues with Leica M9 sensors. The cameras are still available brand new and we can always order more from Leica when needed.
Leica is all about unique products that are peerless, and I think the new Leica M Monochrom fits that perfectly. Of course they understand it won’t be the volume seller so that puts the price point a bit higher.
Leica never planned on launching an M10 today, that should hopefully be something we see at Photokina this year!
So I suppose I respectfully disagree that this is a waste of time. The M9 has been hugely successful for Leica, and they have a clear understanding of the customer base. Thousands of M users came from shooting black and white film and value a beautiful, natural black and white image, and now have the ability to shoot the finest black and white photographs possible with a 35mm sized sensor.
I think the Leica M Monochrom will be a smashing success, and offer breathtaking image quality and the truest, purest black and white shooting experience this side of Tri-X.
