Flash photography with the LEICA R9

General information on using flash units

All flash units and studio flash systems that con-
form to the currently valid ISO standard 10330
or the older DIN 19014 (positive polarity on X
contact) 1 can be connected to the LEICA R9.
Electronic flash units that meet the technical
requirements of 3000/3002 system camera
adaptation (SCA) offer the most versatile range
of options and can be connected to the LEICA R9
via the SCA 3501 or SCA 3502M3 adapters.
Other separate flash units
shoe can also be used and are fired via the cen-
tral contact (X contact).
Studio flash systems and other flash units with
connection cord and standard flash plug can be
connected via the flash connection socket (1.8).

If you want to connect e.g. a studio flash system that does
not conform to the ISO standard to the LEICA R9, please con-
sult the Customer Service department at Leica Camera AG or a
Leica agent.

The use of flash systems from other manufacturers and SCA
adapters for other camera systems is not recommended as
their differing contact position and assignment can lead to mal-
functions or even to damage.
2 with a standard flash
As well as controlling the firing and illumination
of flash units when taking photographs, the
LEICA R9 also makes it possible to selectively
meter the flash performance before taking the
photograph in order to determine the aperture
that should be set (see "Flash metering mode
before exposure - F ", p.178).

Flash sync speed

With standard flash technology, the LEICA R9's
flash sync speed is 1/250 s. Studio flash
systems in particular often have flash burst dura-
tions that are considerably longer. In order to take
full advantage of the full light quantity provided
by these flash units, slower shutter speeds, such
as 1/180 s or 1/125 s are recommended.
When used with SCA 3002 standard flash units
that have an HSS mode (High Speed Synchroni-
sation) and the SCA 3502M3, the LEICA R9 also
allows the use of all faster shutter speeds up to
1/8000s (see "High speed sync flash mode", p. 172).
