Technical data
Camera type Compact 35 mm range- and viewfinder system
camera with mechanically controlled shutter.
Lens connection Leica M bayonet.
Lens system Leica M lenses from 21-135 mm
Exposure metering Exposure metering through the lens
(TTL), selectively with working aperture.
Metering principle The light reflected by a metering spot in
the center of the 1 st shutter curtain is metered. The metering
spot has a diameter of 12 mm and therefore corresponds to
approx. 13% of the full negative format or around
1 /
2
of the
short side of the corresponding frame in the viewfinder.
Metering range (at ISO 100/21°) From 0.03cd/m 2 to
125000 cd/m 2 at room temperature, normal humidity and
aperture 1.0. At ISO 100/21° this corresponds to EV-2 to 20
or f/1 and 4 s (B-setting) to f/32 and 1/1000 s. Flashing of the
left triangular LED in the viewfinder indicates values below the
metering range.
Metering cell for available light (continuous light measure-
ments) Silicon photo diode with convex lens to the top left be-
hind the camera bayonet.
Film speed range Manual setting from ISO 6/9° to ISO
6400/39°.
Exposure mode Manual shutter speed and aperture setting,
adjustment via LED light balance.
Flash exposure control
Flash unit connection
Via accessory shoe with central
contact and/or standard flash connection socket.
Synchronisation On the 1 st shutter curtain.
Flash synchronising speed
11
= 1/50 s; slower shutter speeds
possible.
Flash exposure control Via computer control of flash unit or
via guide number calculation and manual setting for the
required aperture.
Viewfinder
Viewfinder principle
Large, light bright-line range- and view-
finder with automatic parallax compensation.
Eyepiece Adjusted to –0.5 dpt.. Corrective lenses from –3 to
+3 dpt. available.
Image field limitation By projection of pairs of bright-line
frames: For 28 and 90 mm (90 mm only on LEICA MP 0.85) or
for 35 and 135 mm (35 mm only on LEICA MP 0.58), or for 50
and 75 mm. Automatic projection when lens is attached. The
desired frame can be projected using the frame selector.
Parallax compensation The horizontal and vertical differ-
ence between the viewfinder and the lens is automatically
compensated according to the relevant distance setting, i.e.
the bright-line frame automatically aligns with the subject
detail recorded by the lens.
Matching of viewfinder and film image The size of the
bright-line frame corresponds to an image size of 23 x 35 mm
at the shortest setting distance for each focal length. With the
infinity setting, depending on the focal length, approx. 9 %
(28 mm) to 23% (135 mm) more of the image is recorded than
the corresponding bright-line frame shows.
