No
longer
are
you
forced
to
give
up
manual
focusing
on
the
lens
while
you
adjust
your
f/stop!
With
1/3
step
increments
in
both
shutter
speed
and
aperture,
you
can
fine-tune
your
exposure
like
never
before.
This
is
particularly
important
when
you're
shooting
narrow-latitude
transparency
film.
But
the
innovation
of
the
Quick
Control
dial
doesn't
stop
there.
You
can
also
use
it
in
AE
modes,
such
as
Intelligent
Program,
Shutter
Priority,
and
Aperture
Priority,
to
bias
your
exposures
up
or
down
without
leaving
those
modes!
You'll
be
able
to
take
full
advantage
of
the
stepless
accuracy
of
automation
without
being
locked
in
to
the
camera's
meter
reading.
Instead,
just
turn
the
Quick
Control
dial,
and
choose
for
yourself.
Even
when
shooting
vertically
with
the
EOS-l,
the
Quick
Control
dial
is
easy
to
use.
When
you
attach
the
optional
Power
Booster,
you
gain
an
additional
shutter
release
and
AE
Lock
button
to
improve
handling.

Viewfinder
Benefits
Decision-Making
As
you
place
the
viewfinder
of
the
EOS-l
to
your
eye,
you'll
start
to
gain
even
more
confidence
in
this
new
professional
tool.
For
example,
all
data
is
displayed
with
clearly
visible
LCD
elements.
You
won't
have
to
move
your
eye
up
and
down
to
see
critical
information,
as
you
do
with
some
cameras.
You
can
easily
see
shutter
speeds,
aperture
values,
an
exposure
scale,
a
frame
counter,
focus
confirmation,
flash-ready,
AE
Lock,
Exposure
Compensation
mark,
Manual
mode
indicator,
and
a
unique
Auto
8
Bracketing
display.
But
as
you've
come
to
expect
from
Canon,
you
only
see
what
you
need
when
you
need
it.
The
eyepoint
has
been
increased
to
20.2mm--that's
a
full
4mm
increase
over
the
current
F-l.
Finder
magnification
with
a
standard
50mm
lens
has
been
reduced
from
80%
to
72%,
making
the
entire
viewing
area
much
easier
to
see,
especially
for
eyeglass
wearers.
The
next
two
improvements
answer
some
long-time
requests
from
current
Canon
owners:
Virtually
100%
finder
accuracy
and
a
built-in
variable
diopter
control.
The
100%
figure
results
from
the
large-
diameter
EOS
lens
mount
with
its
longer
flange-back
distance.
The
dioptric
adjustment,
placed
to
the
left
of
the
viewfinder
eyepiece,
covers
-3
to
+1
diopters.
If
you
need
more
correction
than
that,
you
can
still
use
the
10
corrective
eyepieces
already
available
for
previous
Canon
SLRs.
There
are
also
7
interchangeable
focusing
screens
for
the
EOS-l.
These
inexpensive
accessories
really
help
to
tailor
the
camera
to
your
personal
preferences.
They
include
the
all-matte
standard
screen,
2
different
grid
choices,
2
split-image
types,
a
standard
microprism,
and
a
special
aerial-
image
screen
for
scientific
applications.
Custom
Function
Control
Lets
You
Personalize
the
EOS-I
For
Your
Individual
Needs.
Speaking
of
individual
preferences,
there
are
8
Custom
Function
Controls
on
the
EOS-l.
These
built-
in
software
adjustments
tailor
basic
camera
operations
to
your
