FLASH EXPOSURE METERING (TTL METERING)

The camera offers a fully automated, camera-controlled flash mode
in conjunction with system-compatible flash units (see p. 135)
and for the auto modes aperture priority and manual setting.
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
displays 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.
