TTL flash
Manual flash provides a fixed flash intensity irrespective of the brightness of
the subject and the camera setting. TTL* flash measures the light from the
subject that is reflected through the lens.
Some cameras enable P-TTL metering, which adds pre-flash to TTL metering,
and ADI metering, which adds distance data to the P-TTL metering.
This flash unit defines all P-TTL and ADI metering as TTL flash and the
LEVEL lamp [AUTO] on the display panel lights up.
*TTL = through the lens
• ADI metering is possible in combination with a lens with a built-in distance
encoder. Before using the ADI metering function, check whether your lens
has a built-in distance encoder by referring to the specifications in the
operating instructions supplied with your lens.
