Leica M-series User Manual 14
Leica engineers were careful to ensure that the
new Leica M series—like its predecessors—
remains compatible with existing series. This
means that objectives, bases, tubes and so on
can be reused.
Objectives
All objectives of this new generation have the
same reference focal length as the objectives of
the MZ generation. If you prefer, you can there-
fore continue to use the previous Leica objec-
tive series.
Tubes
The interface between the optics carrier and
the tube has remained the same, so existing
tubes fit the new M series. The new tubes are
designed for eyepieces with field number 23,
while the predecessor models were only
designed for field number 21, resulting in a
smaller object field.
Eyepieces
The new M-series eyepieces have an audible
and tangible click to provide immediate feed-
back in case of accidental adjustment.
