Operation Useful Situations
Reference 
Page No.
This function is useful for situations in
which silence is required — for exam-
ple, in a quiet theater or at a pro golf
tournament — where the sudden noise
of a camera’s rewind would cause dis-
ruption and be frowned upon.
This function is useful for individuals or
news companies who do their own film
processing. The film leader is left out-
side of the cartridge after the film is
rewound automatically or in mid-roll.
With this custom function, the shutter
always operates at the fastest 1/8000
sec. with the back cover open.
This option is for photographers who
shoot film at ISO settings determined
from their own tests. Setting this func-
tion frees the photographer from having
to change the film speed every time a
new roll is loaded.
1: This option lets the photographer
carry out metering and autofocusing
independently.

2: For sports photography using focus
prediction in AI Servo AF mode, this
option lets the photographer tem-
porarily stop the focus.
When making manual exposure adjust-
ments, this function lets the photograph-
er choose whether to use the main dial
for adjusting the shutter speed or aper-
ture value. This option is convenient for
studio flash photography where the
shutter speed is kept constant while the
aperture is frequently varied to alter
depth of field and exposure.
This function lets the photographer
input shutter speed and aperture set-
tings in any increment that he or she is
used to. 1/2-stop exposure compensa-
tion settings are also possible, providing
wide flexibility to satisfy various shoot-
ing styles.
This option disables the manual focus-
ing capability of the electronic ring pro-
vided on many USM lenses, eliminating
the possibility of accidentally turning the
ring and shifting the focus after autofo-
cusing is completed.

Operation Useful Situations

Setting this function to center-weighted
average metering provides the photog-
rapher with a predictable metering pat-
tern for determining exposure. This is
useful for experienced photographers
who have over many years developed
an ability to accurately determine expo-
sure combining average metering and
exposure compensation.
2, 3: These settings change the bracket- ing sequence to “0  →– → +”, which
is useful when shooting live sub-
jects or changing scenes where the
first shot will most likely capture the
best expression or composition.
1,  3:These settings are useful for pho-
tographers who frequently use
AEB, as it prevents AEB mode
from being canceled every time the
lens is exchanged, the main switch
is set to 
“”, or the film is
rewound or exchanged, and allows
the user to activate AEB mode
using an external setting operation,
eliminating the need to open the
camera’s palm door.
This option is for users who are
annoyed by the AF frame illumination in
the viewfinder, as well as for those who
frequently use manual focusing to
adjust the final focus.
