ATTACHING THE FLASH UNIT
▸ Switch off the camera and flash unit
▸ Slide the foot of the flash unit all the way into the accessory
shoe and use the clamping nut (where available) to secure it
against accidental detaching.
• Movement inside the accessory shoe can interrupt required
contacts and therefore cause malfunctions.
Notes
• The camera and flash unit must be switched off before the
connection is made.
• Make sure that the accessory shoe cover is always in place when
no accessory is attached (e.g. a flash unit).
FLASH EXPOSURE METERING (TTL METERING)
The camera offers a fully automated, camera-controlled flash mode
in conjunction with the system-compatible flash units (see p.
77) for the two exposure modes aperture priority and manual
setting.
An additional brightening control is provided. However, if the ambi-
ent brightness at the shortest possible flash sync time of 1⁄180 s
would result in overexposure, then only a HSS-compatible flash unit
will fire in aperture priority mode. Where that is the case, the shut-
ter speed will be controlled in accordance with ambient light condi-
tions and displayed in the viewfinder.
In aperture priority mode and with manual setting, the camera also
allows the use of additional flash techniques like flash synchroniza-
tion and firing with slower shutter speeds than the sync time
1⁄180 s, which may be interesting in terms of picture composition.
These functions are set on the camera via the menu (please read
the next sections for more information).
The camera additionally communicates the sensitivity setting to the
flash unit. The flash unit can use this information to automatically
adjust its range data, provided the device comes with these dis-
plays and the aperture setting selected on the lens is also entered
manually on the flash unit. The ISO sensitivity setting cannot be
altered via the flash unit on system-compatible units, because the
information is received from the camera.
