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.
