A lot of London photojournalists who used Nikon cameras in the 1960's as far as I remember started doing it because they had some issues with Nikon U.K's advertising about Nikon being the camera professionals used, I forget exactly what it was, it was a long time ago.I thought such was only done with Leicas (and maybe Zenits).
Well, I saw such once and it was a Leica M-something with a Noctilux.
