to
help
you
select an
appropriate
shutter
speed when using a standard
50mm
lens. For
indoor
photography,
with
no
special illumi-
nation,
choose
1/30
of
a second' and
1/60
of
a second
in
a brightly lit room.
For
outdoor
photography,
select
1/125
second
when
cloudy
and
1/250
second
in
sunshine.
To
take
pictures
in
particularly
bright sunshine such
as
at
a beach
in
mid-
summer
or
in
snow-covered
mountains,
use
sh
utter
speeds
of
1/500
sec.
or
1/1000
sec.
The above
mentioned
shutter
speeds
apply when using a standard
50mm
lens,
but
it
is
necessary
to
choose faster
shutter
speeds
when
using lenses
of
longer focal lengths
because
they
are
more
difficult
to
hold
steady.
It
is
generally said
that
the
shutter
speed figure should be greater
than
1 divided
by
the
focal length
of
the
lens in
order
to
ob
-
tain sharp images.
For example, when using a
200mm
tele-
photo
lens,
shutter
speed should be faster
than
1/200
second. Thefefore,
the
shutter
speed
in
this particular case should be set
at
1/250
sec. Image blur can also arise if
the
camera
is
not
properly held. See page

Lens

Aperture

The
adjustment
of
the
aperture
is
used
with
the
shutter
speed
to
get
the
correct
ex-
posure. The
amount
of
light reaching
the
film
is
controlled
by
the
aperture's
size.
On
the
aperture
ring are a series of mark-
ings which indicate
the
proportion
of
the
light
allowed
to
pass
through
the
lens, which are
known
as
f/numbers. When
the
aperture ring
is
set
to
the
next
larger
f/number
on
the
scale
of
the
ring,
the
amount
of light passing
through
the
lens
is
decreased by 1/2. The
lens's brightness
is
based on the smallest
numerical
aperture
value for the lens.
With a
f/2
serving
as
the
standard,
the
com-
parative brightness
at
each
f/stop
will
be
as
indicated below.

Question and answer

Number of questions: 0

The Canon AT-1 is a 35mm film single-lens reflex (SLR) camera that was manufactured and released by Canon in the late 1970s. It is not easily categorized as it falls between the beginner-level Canon AE-1 and the more advanced Canon A-1. The AT-1 features a fully manual exposure control system, allowing photographers to manually adjust the aperture, shutter speed, and focus. It is equipped with a focal plane shutter with speeds ranging from 1 to 1/1000 seconds, plus a Bulb mode for long exposures. The camera offers a through-the-lens (TTL) exposure metering system which aids in achieving accurate exposures. Featuring a sturdy and durable construction, the AT-1 is designed to withstand regular use. Its body is primarily made of metal, ensuring its longevity and reliability. Moreover, it is compatible with a wide range of Canon FD lenses, offering photographers flexibility in their choice of optics. The AT-1 is also equipped with a hot shoe for attaching an external flash and a synchronizing socket for connecting other flash units or accessories. It utilizes a center-weighted metering system which provides reliable light meter readings. Despite its lack of automatic exposure modes and other advanced features, the Canon AT-1 remains a popular choice among photographers who prefer full manual control and value its simplicity and robustness.

Can't find the answer to your question in the manual? You may find the answer to your question in the FAQs about the Canon AT-1 below.

How do I load film into the Canon AT-1?

Make sure you are in a well-lit area and follow these steps: open the back of the camera by pulling up the rewind knob, place the film cassette in the left side of the camera, pull the film leader across to the right side and insert it into the take-up spool, advance the film a few frames until it catches onto the spool, close the back of the camera, and finally, advance the film until the frame counter shows "1."

What shutter speed should I use for a moving subject?

To capture a moving subject with minimal blurriness, consider using a fast shutter speed like 1/500th of a second or faster. This will freeze the motion and result in a sharp image.

How can I adjust the exposure on the Canon AT-1?

The Canon AT-1's exposure can be adjusted by using the camera's exposure control system, which consists of the aperture priority mode. Rotate the aperture ring on the lens to select the desired aperture value, and the camera will automatically adjust the shutter speed accordingly.

How do I know if the battery is low on my Canon AT-1?

If you notice that the LED meter in the viewfinder gradually becomes dimmer or fails to light up, it is an indication that the battery is running low and needs to be replaced. This could affect the camera's exposure metering capability.

What should I do if the film advance lever gets stuck?

If the film advance lever gets stuck, try gently pressing down on the rewind release button, located on the bottom of the camera, while simultaneously turning the film advance lever in the direction of the arrow until it releases. This should allow the lever to move freely again. If the issue persists, it might require professional servicing.
