Setting-
Shutter Speed Priority Method
1
Set the
sh
utter
at
a desired
speed
.
2
Face
the
camera towards the photographic
subject,
look
into the
viewfinder
,
and press
the lever fully
.

Either keep pressing the
lever
or
lock
the
lever
and turn the aperture ring
.
Set the meter needle at the o
index
within
the viewfinder for correct
exposure
.
• Canon's TTL
system
has been adopted in the
·
Canon FT QL which provides the most accurate
photometry.
Under this
system,
the CdS
photo·
cell of the
built-in
meter
is
placed in the closest
position to the two-way -mirror condenser
lens.

• The rectangular
frame on
the
outside of
the
prism
screen within the viewfinder is the same
size
as the CdS
light
receiving area
of the CdS
photocell.
Place
the center of
the photographic
subject within this
frame and measure
the
intensity of
light.
In
this way
the photographer
can decide the best
exposure
for
his
photo-
graphic
needs
.
The TTL
system
makes possible
the measuring of
exposures
in counter -light
conditions.
• Measurement
at "B"
and
"X"
of the
shutter
dial
is
not possible
with
the
exposure
meter
because
"
B" is used for long
exposures
over
one second
,
and
"
X"
is
used for
speedlight.
Exposure Setting-f/Stop Priority Method
1
Set the
lens
aperture at the desired f /stop.
2
Face the
camera towards
the photographic
subject,
look
into
the viewfinder, and press
the CdS actuating
lever.
3
While pressing
or locking
the CdS actuating
lever
,
turn
the shutter
dial.
4
Set the meter needle at the
" o"
index
within
the viewfinder for correct
exposure.
.. Intermediate positions on the shutter speed
dial scale cannot be used, but since any aperture
may be utilized
,
the
shutter
speed should first
be determined when
strictly
considering the
exposure.
It
is
most practical to adjust the
aperture according to this.

During the use of
the
meter
,
there are in
-
stances
of the movement of the needle becom-
ing slack,
owing
to
changes in the degree of
light,
but this
is
due to the characteristics of
the
CdS.
• When
taking
pictures against the light, always
use a
lens
hood.
.. When the subject
is
too bright or too dark and
is outside the range of the built-in exposure
meter
,
the meter needle will point to the top
or bottom zones and will indicate that proper
exposure cannot be obtained
.

able Range
