LEICA M11 Monochrom Rangefinder Camera - Manual (Page 34)

PREPARATION ▸ LENS 34
LENSES WITH LIMITED COMPATIBILITY
COMPATIBLE, BUT MAY POSE RISK OF DAMAGE TO THE
CAMERA AND/OR LENS
– Lenses with retractable tube must only be used with the tube
extended, i.e. never attempt to retract the tube while the lens
is attached to the camera. This does not apply for the current
Makro-Elmar-M 90 f/4 model, as its tube will not retract into the
camera itself and can therefore be used without restriction.
– When using heavy lenses attached to a tripod-mounted camera,
e.g. Noctilux 50 f/0.95 or Leica R lenses with an adapter: Make
sure that the tilt of the tripod head cannot move inadvertently
when the camera is not held. A sudden tilt and impact could result
in damage to the lower edge of the camera bayonet. That is why
you should always use the tripod mount on relevantly equipped
lenses.
COMPATIBLE, BUT EXACT FOCUSING MAY BE LIMITED
Despite the high precision of the rangefinder on the camera, exact
focusing with 135 mm lenses with an open aperture cannot be guar-
anteed due to the very low depth of field. We therefore recommend
stopping down by at least 2 steps. Live View mode, on the other
hand, plus the various setting aids provided, allow unrestricted use
of this lens.
INCOMPATIBLE LENSES
– Hologon 15 f/8
– Summicron 50 f/2 with close-up function
– Elmar 90 f/4 with retractable tube (manufactured 1954–1968)
– Some examples of the Summilux-M 35 f/1.4 (non-aspherical,
manufactured 1961–1995, Made in Canada) cannot be attached to
the camera or cannot focus to infinity. Leica Customer Care can
modify these lenses for use with the camera.
