STROBOSCOPE FLASH MODE
(with system-compatible flash units)
This flash method, in which several flashes are fired during an exposure,
is available in all exposure modes of the camera. The camera will
automatically set the shutter speed needed for selected number of
flashes and their frequency using the flash modes. The light balance
display will indicate if the required shutter speed would result in an
overexposure because of the available light. Where the shutter speed
would result in a too short shutter speed, the time display in the
viewfinder and in the top display will flash. Changing the number of
flashes and the flash frequency, the aperture and/or the shutter speed
will help to compensate the exposure. The focus range of the flash unit,
number of flashes, distance, and of course the aperture are crucial
factors when trying to capture successful stroboscopic images, where
several phases of a motion sequence are captured. Please read the flash
unit manual for more information.
Note
HSS flash technology offers less range.
MANUAL FLASH PHOTOGRAPHY WITH UNIFORM FLASH OUTPUT
The flash output volume will not be controlled if the flash unit is used in
manual flash mode at full power or at permanent partial power (provided
the flash unit offers this setting option). The camera's exposure modes
essentially function the same way as without flash.
The flash is suppressed if the flash sync speed drops below the set value
in mode
or
or if a speed is set below the sync speed in mode

The lens aperture to be set is determined by the flash output, the
sensitivity and the distance to the subject. Conversely, the partial flash
output to be set is determined by the aperture, the sensitivity, the focal
length and the distance to the subject (see flash unit manual).
FLASH PHOTOGRAPHY VIA THE LOWER LEMO
Flash units and large studio flash systems can be connected to the lower
LEMO® jack via a cable using the LEMO® plug (supplied). The LEMO®
jack comes with an automatic lock to prevent accidental disconnection.
The camera cannot "recognize" the flash unit and will therefore behave as
if no flash unit was attached. The exposure time must be set manually to
the flash sync speed 1⁄125 s or 1⁄1000 s with central shutter, or to slower
speeds. There will be no automatic switch-over. The flash ready and
control displays are not active.
