I was shocked reading about this article digital photography school: Life with a rangefinder. In this article, the author states that he replaced his bag of Canon camera bodies and lenses for a $13,000 digital rangefinder Leica M system camera. The only advantages is the compact size, silent operation and light weight.
Obviously this is a retro thing, and I cannot imagine myself using this camera for stunning black and white images. I will stick with my HS25EXR camera.
