Setting Setting Description Description
B 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.
C 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.
D 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.
