Just placed an order for five prints, all of which are for me rather than for others, and I noticed that they were all within 500 exposures of each other, many of which (100?) were test images, and many were double exposures of the same scene as I explore what this lens does at different apertures. Still, better than 1:100. That, for me, is a veritable storm of keepers. Almost all were with the M9 and my only M-mount lens. As kitschy as it sounds, I think that's a fairly good testimony of the man-machine relationship I'm developing with this thing. I'll probably start acquiring other M lenses even when I have perfectly good lenses in those ranges but without rangefinder coupling to help, ah, nurture this budding friendship.
