Hi Richard,
Actually the were taken with a Nikon D70 or D2x ( I can't remember which one I used). I had a Leica M6 for a few years, but the world was going digital and I feared I would be left with a very expensive paper weight.
Yesterday I read an article on DP review that hinted at a Digital M6 finally being released by Leica.
Oh well, we will see, but I am happy for now.
