Adjusting the brightness of the image
When shooting with the flash, you can adjust the amount of flash light
alone, without changing the exposure compensation. You can only change
the exposure of the main subject within the flash range.
Fn button t (Flash Comp.) t Select the desired setting
Toward +: Makes the flash level higher.
Toward –: Makes the flash level lower.
Notes
• [Flash Comp.] cannot be set when the exposure mode is set to [Intelligent Auto],
[Superior Auto], [Sweep Panorama], or [Scene Selection].
• The higher flash effect may not be visible due to the limited amount of flash light, if
the subject is outside the maximum range of the flash. If the subject is very close, the
lower flash effect may not be visible.
Exposure compensation and flash compensation
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.

ADI: Advanced Distance Integration
TTL: Through The Lens
• When [ADI flash] is selected, using a lens that is provided with a distance
encoder feature provides more accurate flash compensation by using
more accurate distance information.

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