There is a new Leica M Monochrom Typ 246 Oslo Edition camera that comes with a black version of the Leica Summaron-M 28mm f/5.6 lens (Google translation):
“The special edition is available in only 10 copies worldwide and is only available from Leica Store Oslo. The text ‘OSLO’ is engraved on the back of the camera housing and on the front of the lens. Each body and lens are numbered, eg: OSLO # 01.
The ultra-compact wide-angle lens Summaron-M 28mm f5.6 ASPH with metal solder is included. This is a modern edition of a Leica classic from 1955. For this special edition, the lens comes with a unique black surface – as it is first in the world. Included in the elaborate gift box is also a black camera frame in leather, battery, charger and authentication certificates.”
