Auto/Manual Control
The Main Electronic
Input Dial
The EOS-l is the first camera to
incorporate two electronic input dials.
The main dial sets the shooting
mode, the
AF mode and the metering
mode.
It selects shutter speeds or aper-
ture values during shutter-priority or
aperture-priority operation.
It selects
the film winding mode, number
of
multiple exposure presets, and manual
film speed settings.
It sets the auto
exposure bracketing values and
exposure com-
pensation. And
it also selects the
EOS-l's unique
Custom Function
Controls.
The Quick Control
Dial
In the AE mode, the quick control
dial can be used to set exposure
compensation values. In the manual
exposure mode, this dial can
be used to
manually set aperture value or shutter
speed - depending on the custom func-
tion selected -
with the main dial
setting the other
value. A switch
allows the dial
to be disengaged.
Metered Manual
Control
The two electronic input dials
make metered manual operation easy
to control. In this mode, the shutter
speed
is set using the main dial while
the aperture
is set by the auxiliary dial.
These values are displayed digitally
in the viewfinder. And the metered
manual exposure's deviation from the
correct exposure indicator
is clearly
indi::ated
by the moving marker on the
exposure scale in the viewfinder for
instant confirmation. The "matching-
needle"
feel of the system has a
mechanical sense that
is reliable and
reassuring.
Equally reassuring
is the fact that
the viewfinder provides virtually
1000/0
coverage. This, plus instant depth-of-
field
preview, allows the photographer
to be sure
of the final results.
100%
Manual Focus
All Canon EF lenses have a switch
on the lens barrel that activates manual
operation. But the
L series lenses with
ultrasonic motors also allow manual
focusing in the One-Shot
AF mode
in conjunction with AF operation.
Because the electronic focusing ring
system can
be used even in the AF
mode, the photographer can always
make the final decision on focus. The
manual focusing
feel is pleasingly
smooth, too, without the rasping opera-
tion common to some
AF lenses. The
complete range
of USM lenses covers
focal lengths from 28mm to 600mm,
including zooms, and features the
extraordinarily bright 50mm fi1.0L.
