Exposure compensation changes the shutter speed, aperture, and ISO sensitivity (when
[AUTO] is selected) to perform the compensation.
Flash compensation only changes the amount of flash light.

• When [ADI flash] is selected, using a lens that is provided with a distance
encoder feature can perform more accurate flash compensation by using
more accurate distance information.
Notes
• When the distance between the subject and the external flash (sold separately)
cannot be determined (wireless flash shooting using an external flash (sold
separately), shooting with an off-camera flash using a cable, shooting with a macro
twin flash, etc.), the camera automatically selects Pre-flash TTL mode.
• Select [Pre-flash TTL] in the following cases, as the camera cannot perform flash
compensations with ADI flash.
– A wide panel is attached to the HVL-F36AM flash.
– A diffuser is used for flash shooting.
– A filter with an exposure factor, such as an ND filter, is used.
– A close-up lens is used.
• ADI flash is only available in combination with a lens that is provided with a
distance encoder. To determine if the lens is equipped with a distance encoder, refer
to the operating instructions supplied with the lens.
• This item cannot be set when the exposure mode is set to Sweep Panorama, 3D
Sweep Panorama, or [Night Scene]/[Hand-held Twilight] in Scene Selection.

This method controls the lighting of the flash, factoring in the
focus distance information and light metering data from the
pre-flash. This method enables an accurate flash
compensation with virtually no effect from the reflection off
the subject.
This method controls the amount of flash light depending on
the data only from pre-flash light metering. This method is
susceptible to the reflection off the subject.
