Additional functions
• remains continuously lit after taking the picture, and the other
displays go out:
The flash power was sufficient for standard exposure, the flash
remains ready for use.
• flashes quickly after release (at 4Hz), the remaining displays
have gone out, however:
The flash power was sufficient for standard exposure, the flash
remains ready for use.
• goes out after taking the picture, together with the other dis-
plays:
the flash power was not sufficient for standard exposure, e.g.
due to the choice of too small an aperture for the subject. If the
flash unit is set to a lower output level, because of the lower
power requirement it may be ready for use despite the flash LED
not lighting up.
When the flash unit is set to camera control (A) or manual
mode (M)
• does not appear does not appear despite the flash unit being
switched on and ready for use:
On the camera, a shutter speed is set manually that is faster
than
1
⁄
180
s. In such cases the camera will not fire the flash unit
even though it is switched on and ready for use.
• flashes slowly (at 2Hz) before the picture is taken:
The flash unit is not yet ready for use.
• is lit up before the picture is taken:
The flash unit is ready for use.
Flash mode with fast shutter speeds (High Speed Sync�)
Fully automatic, i.e. camera controlled, HSS flash operation is
available with this camera when using correspondingly equipped
Leica flash units, with all shutter speeds and in aperture priority
and manual exposure modes. The camera activates it automatically
if the selected or calculated shutter speed is faster than the sync
speed of
1
⁄
180
s. If the flash unit is set correctly, this change does
not require the photographer to do anything else.
Important:
The range for HSS flash is significantly lower than for TTL flash.
