Leica M Cameras cost about 7000$ without even a objective, compared to DSLR which much more qualities, which cost only a quarter of this.
Only very few of real photographers use them, much to pricey....but something magic about the pictures and bokeh really exists
But there are rich boys loving to show the red Leica dots on their camera - nobody likes these guys, but they keep this little manufacturer alive....
I'm a pro photographer. Leica does have their "ambassadors" like any other brand. However, most Leica users are upper class hobbyist photographers or artistic photographers. Leica's bread and butter come from their optics which is used in many applications (science, medical, etc) and of course, their name (example Panasonic cameras with Leica optics).
