Other Meaningful Marks. Some of Leica s words are more meaningful. Mark Meaning ASPH Aspherical APO Apochromatic Tele, Telyt Telephoto Vario Zoom Tri*, Zoom (see Note) *Note Because Leica s M camera finders only work at a few fixed focal lengths, Leica s zooms for their rangefinder cameras only stop at three click-stopped values corresponding to the few available frame lines of the M cameras. Since Leica s zooms only stop at three settings, Leica calls them Tri-Elmar to avoid the word zoom.
