• Do not open the bottom cover nor remove the
memory card or the battery whilst the red LED (1.31)
at the bottom right of the monitor (1.32) is flashing,
indicating picture recording and/or data being saved
to the card. Otherwise the unsaved (or not completely
saved) picture data may be lost.
• As electromagnetic fields, electrostatic charge,
and defects on the camera or the card can lead to
damage or loss of the data on the memory card,
we recommend that you also transfer the data to a
computer and save it there (see p. 148).
• For the same reason, it is recommended that the card
is always stored in its antistatic cover.
LEICA M LENSES
Generally: Most Leica M lenses can be used on the
Leica M Monochrom. Details on the small number
of exceptions and restrictions can be found in the
following notes.
They can be used regardless of the lens features, and
whether it does or does not have 6-bit coding in the
bayonet (latest version).
Even without this additional feature, i.e. when using
Leica M lenses without identification, the Leica M
Monochrom will deliver excellent pictures in most
situations.
To ensure optimum picture quality in these situations,
we recommend entering the lens type (see "Turning
lens type identification on/off", p. 114).
Important:
• Cannot be used:
– Hologon 15mm f/8
– Summicron 50mm f/2 with close up
– Elmar 90mm f/4 with retractable tube
(manufactured from 1954-1968)
– Some examples of the Summilux-M 35mm f/4
(not aspherical, manufactured from 1961-1995,
Made in Canada) cannot be fitted to the Leica
M Monochrom or will not focus to infinity. Leica
Customer Service can modify these lenses so that
they can be used on the Leica M Monochrom.
• Can be used, but risks damaging the camera
or lens
Lenses with retractable tube can only be used with
the tube extended, i.e. their tube must never be
retracted into the Leica M Monochrom. This is not
the case with the current Macro-Elmar-M 90mm f/4,
whose tube does not protrude into the camera body
even when retracted. It can therefore be used without
any restrictions.
• Can be used with restrictions
Despite the high precision of the rangefinder on the
Leica M Monochrom, exact focusing with 135mm
lenses with an open aperture cannot be guaranteed
due to the very low depth of field. Therefore, stopping
down by at least 2 stops is recommended.
• Can be used but are excluded from exposure
metering
– Super-Angulon-M 21mm f/4
– Super-Angulon-M 21mm f/3.4
– Elmarit-M 28mm f/2.8 with serial nos. before
2 314 921.
Note:
Leica Customer Service can upgrade many Leica M
lenses with 6-bit coding. Enquiries for specific cases to
(address, see p. 167).
