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 defines all P-TTL and ADI metering as TTL flash and

displays on the data panel.

*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.
