Lenny Kravitz, by virtue of being a medium-popular pop-rock singer, and by virtue of apparently sometimes using a Leica camera, has achieved the status of now being a Leica designer!
His "design" consists of no more changes to the camera than having machines and assistants rubbing off the black paint in corners and some areas on a black Leica camera, so it looks like it has been used a lot! Awesome...
(Having seen some documentaries about how things work in Celebrity World, I would be surprised if Lenny even had anything to do himself with this design "idea".)
Read Mike Johnston's no less sarcastic take on this.
