Technical data

Type of camera Compact 35 mm rangefinder system camera
with electronically controlled shutter and 2 mechanically
controlled shutter speeds.
Lens mount Leica M-bayonet.
Lens system Leica M-lenses from 21–135 mm.
Exposure metering Exposure metering through the lens (TTL),
selectively with working aperture. Center-weighted integral TTL
metering for flash exposure using system-compatible SCA 3000
standard flash units.
Metering principle The light reflected from a measuring field
in the center of the 1st shutter curtain is measured. The measur-
ing field has a diameter of 12 mm and is therefore equal to
approx. 13 % of the total negative format or in the viewfinder
to approx. 2/3 of the short side of the valid viewfinder frame.
Metering range (at ISO 100/21°) From 0.03 cd/m
at room temperature, normal humidity and aperture 1.0. For ISO
100/21° this corresponds to EV -2 to 20 or f/1.0 and 4s to f/ 32
and 1/1000s. Flashing of the left-hand triangular LED in the
viewfinder indicates working in conditions of low light.
Photocell for ambient light (continuous light metering) Silicon
photodiode with condensor lens to the top left behind the
camera bayonet.
Film speed setting range Optionally automatic setting for
DX-coded films from ISO 25/15° to ISO 5000/38° or manual
setting from ISO 6/9° to ISO 6400/39°. Additional setting of an
exposure compensation (± 2 EV) makes it possible to use films
with speeds from ISO 1.5/3° to ISO 25000/45°.
Exposure mode Optionally automatic control of shutter speed
– with corresponding digital display – with manual aperture
selection (aperture priority mode), or manual setting of shutter
speed and aperture and compensation using LED light balance.
Flash exposure control
Flash unit socket Accessory shoe with central- and control
contacts or standard flash connection socket.
Synchronisation Optionally with the 1st or 2nd shutter curtain
(with appropriate flash unit and SCA-3502 adapter).
Flash synchronising speed
"AUTO"; slower shutter speeds can be used with manual setting;
faster shutter speeds (1/250 s, 1/500 s, 1/1 000 s) can be used
with manual setting if attached flash unit has the "High Speed
Synchronisation" function and an SCA-3502 adapter is used.
Flash exposure metering (with SCA-3501/3502 adapter or
SCA-3000 standard flash unit, e.g. LEICA SF20):
TTL control with center-weighted integral metering.
Flash photocell Silicon photodiode with condensor lens to the
bottom right behind the camera bayonet.

Displays in flash mode
Ready to use Constant illumination of flash symbol LED in the
viewfinder.
Success check Continued illumination or temporary rapid
flashing of the LED after exposure, underexposure shown by the
LED temporarily going out.
