I own the Makina 67, 670 and W67. I am totally impressed by the lens signature of the Makina 67 and 670 for portraiture. They are somehow sharper than my Hasselblad 503CW with the CFE 80mm lens. I bought a Mamiya 6 but returned it because I found the build not as solid as the Makina. I hear the Mamiya 7 is sharper than the Makina but sometimes sharpness isn't everything...check out this shot on my flickr account:http://www.flickr.com/photos/the_clo...57628680978073
