TTL metering (Through The Lens):
The TTL flash metering system controls the flash during the
exposure automatically.
Pre-flash metering:
In combination with TTL metering, a pre-flash fires before the
main exposure. The pre-flash is metered with 14 segment
honeycomb pattern and fed back to the flash exposure sys-
tem to determine the reflectance of the scene.
ADI metering (Advanced Distance Integration):
Flash metering is controlled by distance information from D
series lenses in addition to TTL metering. With the 5600HS
(D) and 3600HS (D) accessory flash units, a pre-flash is also
used. With ADI metering, flash output is less influenced by
background conditions or the subject’s reflectance.
When pre-flash fires, a flash/color meter cannot meter accurately. This
is because the purpose of pre-flash is to assist ADI/Pre-flash meter-
ing, not to provide illumination for the picture.
Cancel HSS function of the
program flash (see flash manual) or eliminate the influence on metering using
Custom 11-2 (p. 111). However, if you use the test-flash button on the
flash, the pre-flash will not fire.
Use of a Flash/Color Meter with Pre-Flash
When Using a Close-up Diffuser, Certain Filters and Lenses
When close-up diffuser CD-1000, or a filter whose stop’s increase is
not 0 (i.e., ND) is used, or when the focus-range limiter or macro release
of certain lenses are used, the proper exposure will not be obtained by
ADI or Pre-flash metering.
Cancel HSS function of the program flash (see
flash manual) or eliminate the influence on metering using Custom 11-2 (p.
111).

• When an off-camera cable or bounce flash is used, the TTL metering mode
will be automatically set.
• High-speed sync does not work with this camera even when the flash has the
high-speed sync function. However, when using the (D) flash, turn the HSS
on in order to fire the pre-flash for ADI or DI metering.
Flash Metering
Flash metering changes according to the flash unit and lens being used.

The accessory flash units fit in the shoe located on
