It's good to hear about Spotmatics. I never owned a Leica or Canon. After a short stint in 35mm, I went to MF for a long time. A little 4x5 that I still have but the Pentax was all ways on my mind. I have quite a few lenses but they are off-brand and that is the next thing to work on. I'm pretty sure the glass was good then but not like the Leica stuff. I saw a test that a friend( that worked at a camera shop) did with the Leica and Nikon lenses. There was a difference in the quality of the prints he showed me from the two systems. I don't think I'll ever own a Leica ( since they are a little above my income now) but maybe a deal will come around that I can't live without.
