I noticed that when I mounted the summicron infinity was short but it changed in the RF patch; the left side of the patch was fine, the middle was short, and the right side was worse. This did not occur when the the DR was mounted. The reason I could tell this was because I was shooting a large radio antenna atop a residential building against the sky so the degree of change in the patch was obvious compared to a more complicated scene. I also noticed that the lens was professionally coded for digital, not one of those home kits. I wonder if Leica changes the mount on these lenses?? I'll see the results when I develop the film. Stay tuned. Chris On Sun, Dec 4, 2011 at 3:01 PM, Chris Saganich <csaganich at gmail.com> wrote: > Yes, If I had a M9 I could easily check.
