FLASH EXPOSURE METERING (TTL METERING)

In conjunction with system-compatible flash units (see p. 173), the
camera offers a fully automated flash mode, which is also available
in the exposure modes Aperture-Priority and Manual.
In aperture-priority mode and with manual setting, the camera
furthermore allows the use of other interesting flash techniques like
flash synchronization and firing with slower shutter speeds than the
max. sync time.
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.
