Description

Flash compensation/
output

The options available vary with ﬂ ash control mode.

•

TTL: Adjust ﬂ ash compensation (the full value may not be
applied if the limits of the ﬂ ash control system are exceed-
ed). In the cases of the EF-X20, EF-20, and EF-42, the select-
ed value is added to the value selected with the ﬂ ash unit.

•

M/MULTI: Adjust ﬂ ash output (compatible units only).
Choose from values expressed as fractions of full power,
from ⁄ (mode M) or ¼ (MULTI) down to ⁄ in increments
equivalent to ⁄ EV. The desired results may not be achieved
at low values if they exceed the limits of the ﬂ ash control
system; take a test shot and check the results.

Flash mode (TTL)

Choose a ﬂ ash mode for TTL ﬂ ash control. The options avail-
able vary with the shooting mode (P, S, A, or M) selected.

•

E (FLASH AUTO): The ﬂ ash ﬁ res only as required; ﬂ ash lev-
el is adjusted according to subject brightness. A

p icon

displayed when the shutter button is pressed halfway indi-
cates that the ﬂ ash will ﬁ re when the photo is taken.

•

F (STANDARD): The ﬂ ash ﬁ res with every shot if possible;
ﬂ ash level is adjusted according to subject brightness. The
ﬂ ash will not ﬁ re if not fully charged when the shutter is
released.

•

G (SLOW SYNC.): Combine the ﬂ ash with slow shutter
speeds when photographing portrait subjects against a
backdrop of night scenery. The ﬂ ash will not ﬁ re if not fully
charged when the shutter is released.

Sync

Control ﬂ ash timing.

•

H (1ST CURTAIN): The ﬂ ash ﬁ res immediately after the shut-
ter opens (generally the best choice).

•

I (2ND CURTAIN): The ﬂ ash ﬁ res immediately before the
shutter closes.

•

AUTO FP(HSS): High-speed sync (compatible units only). The
camera automatically engages front-curtain high-speed
sync at shutter speeds faster than the ﬂ ash sync speed.
Equivalent to 1ST CURTAIN when MULTI is selected for ﬂ ash
control mode.
