Here is another Leica M concept camera, this time by Shanghai-based industrial designer Wencheng Zhang:
“In that same vein, Zhang’s version of the Leica M is imagined to be precisely forged from a single block of aluminum alloy, imparting the form with a similar unibody confidence with what seems to be a cross between the Leica M11 and the smaller machined TL2. The designer himself says the concept’s minimalist form was actually inspired by a film camera of much older origin: Leica’s first ever camera, the Ur-Leica Replica.”
