• It is imperative to take note of the shortest flash sync speed,
as it determines whether a "normal" flash or an HSS flash is
fired.
▸ Tap the shutter button before each flash exposure to activate
exposure metering
• The flash unit may not fire if this step is missed by pressing
the shutter button down completely and skipping these
settings.

Notes
• A flash unit that is not ready to flash may cause incorrect
exposures or error messages.
• Studio flash systems may have a very long flash firing duration. It
may therefore be advantageous to select a slower shutter speed
than 1⁄180 s when using such a system. The same applies for
RF-controlled flash firing for so-called "off-camera" flashes, as
the transmission time may cause a delay.
• Serial exposures and automatic bracketing with flash are not
available.
• Depending on the setting selected in the
the camera may not support slower shutter speeds, because an
increase in ISO sensitivity takes priority.
• Use a tripod to prevent blurring at slow shutter speeds.
Alternatively, you can select a higher sensitivity.
