I went to the bdmitrov site, and after careful reading of the various pages, and a careful examination of my MZ-M , the lenses I have, and the K100D body, it's all clear now. I even see why one has to press a button to get the DSLR bodies to take a meter reading with M lenses: the body has no stop-down coupler.
