Part 1: General Information
10. When automatic focusing point selection,
AI Servo AF, and continuous shooting are
used in combination, the continuous shoot-
ing speed may become irregular if the sub-
ject moves to another focusing point.
11. With interchangeable focusing screens Ec-
A, Ec-B, Ec-I, and Ec-L, only spot metering
or centerweighted averaging metering can
be used.
12. When using spot metering during continu-
ous shooting, the first shot will be used for
AE lock and subsequent frames will be
based on the AE lock of the first image.
Even with single-frame shooting, pressing
the shutter button completely during film
advance will retain the previous AE lock
setting.
13. To remove the focusing screen from the
camera, turn the lens mount upward and
release the locks for the screen's frame.
14. If AI Servo AF is set for flash photography,
the Speedlite's built-in AF-assist beam will
not be emitted. (In the One-Shot AF mode,
the beam is emitted automatically when
necessary.)
15. When Battery Pack BP-E1 is attached,
size-AA lithium batteries cannot be used.
16. With the 550EX attached, the FEB shooting
sequence follows the 550EX's settings
instead of the CF-9 (AEB sequence
change).
17. The AEB sequence is different from the
EOS-1N's (including CF-9). The standard
sequence is 0, -, and +. With the Custom
Function, it is -, 0, +.
18. When date imprinting is enabled during con-
tinuous shooting, the continuous shooting
speed will be slower.
If the subject moves from one focusing point to
another, focusing might be disrupted for an instant. It
takes time to refocus. (Same as with EOS-1N).
The focusing screen's prism at the center is clear.
Therefore, evaluative, partial, focusing point-linked
spot metering (A0: center used) may result in error.
Designed to suit the actual picture-taking conditions.
It is not necessary to release the shutter button from
the halfway position first to take the next picture.
If the lock is released while the camera is upright on
a table, the screen will bound when it drops to the
replacement position. The resulting shock may cause
the screen to jump out.
Since it does not match predictive AF very well, this
has been incorporated in the design.
One-Shot AF is recommended for flash photography.
New lithium batteries initially have a high effective
voltage which may damage electronic circuits in cam-
eras and lenses.
For flash exposure compensation, the Speedlite takes
priority. This is to prevent confusion on FEB and give
the Speedlite priority.
With the EOS A2/A2E/5 and later EOS cameras, the
AEB sequence starts with a correct exposure (0, -,
+). This gives the user a better chance of capturing a
great picture. The EOS-1N's AEB sequence is based
on the EOS-1's with -, 0, and +. There are plans to
apply this AEB bracketing sequence to APS cameras
as well. Canon's AEB bracketing sequence will be
standardized to 0, -, +.
This is due to the time it takes to imprint the date.
