Well, I don't see that value for the Sony RX1. To me, the RX1 is very expensive and has limited application. I do not find a 35mm lens adequate as my only lens for a FF camera. Now, had it had a zoom lens or better yet the ability of interchangeable lenses, that would be a different story.
There's a long and rich tradition of cameras sold with only a 35mm lens. Konica Hexar, Fuji GA645, Fuji X100, and probably a whole host of ones I can't recall now. Surely they are specialist cameras as any single focal length camera has to be.
The RX1 is a technological accomplishment, giving you the smallest 35mm full frame sensor in the smallest package. It is an extraordinary camera based on that alone. Along with that, you get an extremely fine Carl Zeiss lens, and in this forum you can see the enormous quality such fine glass can produce from many members here.
Yes, the RX1 is expensive but at least it gives you a pretty ground breaking camera for that money. I see nothing of interest at all with what this Leica can produce, at this price point.
