On his blog, photographer Ming Thein has published a lengthy review of the Leica M-Monochrom, the newly released Leica M rangefinder with a black-and-white sensor. 

A skilled photographer, Thein is also a user of the Leica M-9, the similar Leica rangefinder with a Bayer-pattern color sensor. His review contrasts the sensors in these two cameras and also includes a series of highly detailed and tonally rich black-and-white images taken with the new camera.
