The mode dial is mechanically protected against accidental
adjustment in every position, release button behind the dial is
locked automatically when the dial is moved to a new position
and the button is not pressed.
Flash exposure control
Flash unit connection Via accessory shoe with central and
control contacts or standard flash connection socket.
Synchronisation Flash sync speed: X = 250 s; optionally on
1 st or 2 nd shutter curtain; flash possible with faster shutter
speeds (1/350 s – 1/8000 s) with appropriately equipped flash
units ( HSS mode) and SCA 3502M3 adapter.
With system-compatible flash units (SCA 3000/3002 stan-
dard with SCA 3501/3502M3 adapter or LEICA SF 20) TTL
control with center-weighted integral metering, computer-, i.e.
flash unit-controlled with automatic transmission and conside-
ration of film speed, exposure compensation and set lens aper-
ture, with appropriately equipped Leica R (ROM) lenses and
flash units (with zoom reflector) automatic adjustment of flash
illumination to the focal length used, all exposure modes can
be used, accordingly different exposure levels and proportions
of available and flash ligh, in P fully automatic with optimised
control for balanced photographs with the proportions of
available light increased and flash light reduced according to
the situation, alternatively manual flash exposure compensation
1
(± 3 / EV) possible.

With any flash unit (e.g. studio flash systems) Selective TTL
metering flash firing before exposure, display of metering result
in viewfinder and rear panel LCDs.
High-speed sync flash mode For flash photography with faster
shutter speeds than the sync speed (1/350 s – 1/8000 s) and
aperture settings between full aperture and f/5.6 (with slower
shutter speeds and smaller apertures, automatic selection of
normal manual flash – in M HSS – or TTL - in TTL HSS – flash
exposure). The emission of several flashes in rapid succession
creates an effect similar to that of a constant light source,
exposing the entire image aperture evenly while the shutter is
moving.
Optionally in exposure modes m or A . Only with appropriately
equipped flash units (with High Speed Synchronisation
mode/s) and SCA 3502M3 adapter.
In flash unit M HSS mode, camera exposure mode m and shut-
ter speeds faster than 1/250 s: Adjustment of exposure of
ambient light according to camera's light balance. Determinati-
on of flash exposure based on guide number calculation
(corresponding range shown in flash unit display) by adjusting
shutter speed and/or aperture and/or flash output settings to
the subject distance (with correct exposure of ambient light,
range can be adjusted only by changing the flash output). With
a manually set ( m ) shutter speed of 1/250 s or slower, flash
exposure is at the manually set output level.
In flash unit TTL HSS mode (essentially used as fill-in flash at
2
EV), camera exposure mode m or A and shutter speeds

faster than 1/250 s: Determination of automatic flash exposure
by firing a pre-flash with selective metering of the main subject
(no flash function if fired without pre-flash). Metering result
remains stored for an extended period (20 s), regardless of the
result of the ambient light metering and setting, so that the pic-
ture detail can then be freely selected. Metering memory-lock
(in A ) for ambient light possible in any case. Any number of
pre-flash measurements are possible before taking the photo-
graph. Manual flash exposure compensation of ± 3
