Roland, these shots are with the Type II Rigid, the ~1970 lens that I got from JDOS2 with his M3. The M3 is modified to focus to 0.7m, which matches this lens. I also have the Type I Rigid, and just sold a different Type I Rigid to Robin that I cleaned myself. I also have the collapsible Summicrons, two really clean ones, an LTM and M-Mount (Which I made out of two lenses). I also have a third collapsible Summicron in M-Mount with the front element that I recoated myself.
I go walking around Leesylvania State Park here in Virginia a good bit, and use that brick chimney for a lot of comparative lens tests.
