Part 2: Technical Information
b. Depth-of-field AE
(1) With a camera-selected focusing point: Like the EOS 650, the two DEP
points are specified with the center focusing point.
(2) With a dial-selected focusing point: Like the EOS 650, the two DEP points
are specified with the dial-selected focusing point. (After the first DEP point
is specified, a different focusing point cannot be used to specify the second
DEP point.)
(3) With an eye-selected focusing point: The two DEP points can be specified by
an eye-selected focusing point. The exposure is set by the current exposure
mode when the shutter button is pressed halfway the third time. The expo-
sure for evaluative or partial metering (Custom Function No. 8 set to 1) is
weighted around the eye-selected focusing point when the shutter button is
pressed halfway the third time.
2. AE lock
In the One-Shot AF mode and or the AI Focus AF mode's One-Shot AF mode, autoexpo-
sure is locked automatically when focus is achieved. Also, the AE lock button can be
used to lock the autoexposure in any metering mode. The AE lock is effective for four
sec. after the AE lock button is released. Each time the AE lock button is pressed, it
locks the current AE setting. In the manual exposure mode, pressing the AE lock but-
ton starts the metering. To cancel, wait until the AE lock turns off or turn the metering
mode dial or press the flash button. When the 380EX is used, the AE lock button func-
tions as an FE lock button. This will be covered later.
3. Exposure compensation
With autoexposure bracketing (AEB) and manual exposure compensation, the exposure
can be adjusted up to ±2 stops in half stops. When AEB is set, a bracketing sequence of
correct exposure, underexposure, and overexposure can be shot singly or continuously
depending on the film advance mode. In the manual exposure mode, exposure compen-
sation can be set with the Quick Control Dial.
4. Manual exposure
Like the EOS 5/A2E, the Main Dial sets the shutter speed and the Quick Control Dial
sets the aperture. Metered manual is used. (USA versions use + /- symbols instead of
the exposure level scale.)
5. Flash exposure compensation
Flash exposure compensation with the built-in flash works in the same way as with the
EOS 5/A2E. With the built-in flash popped up, press the Function button to set the
flash exposure compensation mode. Then turn the Main Dial and Quick Control Dial to
set the flash exposure compensation amount. The flash exposure compensation amount
can also be set with an external flash unit. When flash exposure compensation is set
with an external flash unit attached to the camera on the hot shoe or with the TIL Hot
Shoe Adapter, it overrides any flash exposure compensation amount set with the cam-
era. If multiple flash units are used, flash exposure compensation can only be set with
the camera.
6. Shutter
This is the same shutter unit found in the EOS Elan. The shutter design specifications
are also the same.
