One-year Duration 6V Battery
   The AT-1 is powered by only one compact 6V silver oxide
battery with enough power for 20,000 shutter releases. lt should
last one year under normal use.





Conveni€nt Memo Holder
   The back of the AT-1 features a memo holder very useful for
keeping at hand such data as film speed or location. The film
box end torn off  f its perfectly into it.
Viewf inder  I nformation
   The split-image/microprism rangef inder is in the center of the
AT-1's viewfinder and meter and aperture needles are on the
right. The proper exposure range is clearly shown by means of
two index marks. The upper one serves as the battery check
index mark.





Canon Breech-lock Mount
   The AT-1 also has Canon's  exclusive breech-lock mount to
make use of the advantages of all FD and most FL lenses and
enables instant change from one lens to the other.

Canon, a leader in photographic technological breakthroughs,
astounded the world of photography by developing the Canon
AE-1, an automatic exposure camera employing the utmost  in
electronic sophistication. Now, for photographers desiring more
personal control over their own photography, the AT-1 has been
designed. lts streamlined, compact body is molded in the image
of the AE-1, Canon's famous electronically controlled SLR, but
with match-needle exposured control for a more direct, personal
decision-making  in creativity.
   Thus, AT-1 photography means a totally new involvement,  a
new pleasure in creative photography. With the AT-1, there is no
complex gadgetry to determine aperture or shutter speed. lt  is
all up to your own judgement, to a search of your own.
   For perfect accuracy in exposure metering, just take a look
into the viewfinder. Located to the right are two needles. In
order to obtain the proper exposure you simply align the circular
aperture needle with the meter needle. lt is all beautifully simple.
And the viewfinder is amazingly uncluttered to give you a totally
unobstructed view.
   With the AT-1, you will discover the pleasure of SLR photog-
raphy your own way.


Tho Utmost in Opeation and Handling Ease





   The AT-1 is an unbelievable lightweight SLR camera that has
been designed to fit perfectly in your hands for easy handling.
All controls on the AT-1's compact body are within easy reach
  ,d respond without hesitation to your fingers' every command

www.butkus.us
which saves valuable seconds and makes it impossible to miss
that once-in-a-lifetime*hot. To further smoothness of operation,
many of its controls perform tno or more functions which elimi-
nate any unnecessary groping for controls. For example, the
film speed (ASA) can be set by pulling up the outer ring of
the shutter speed dial; the battery power is checked by turning
the main switch to the "C" and turning itto "OFF" will cancel
the self-timer. The shutter release collar doubles as shutter
lock and self-timer switch. Also, the Power Winder A and Speed-
lite 177A couple instantaneously to all the camera functions for
quick, error-free photography in any light.
   Since its body weighs only 590g. and it can accept a host of
Canon accessories, the AT-1 is truly a milestone in convenience
and handling ease, allowing the photographer to center 100%
of his attention on creative photography.

A Viewfinder for Creative Composition
   By using the extremely accurate Central Emphasis Metering
system in the AT-1, optimum exposure is always obtained.
   Because the meter needle is coupled to the shutter speed,
aperture value and film sensitivity in Canon FD lenses, perfect
full-aperture metering  is possible. Perfect stoppeddown metering
is assured with Canon FL lenses.
  To the right of the viewfinder, you can find the meter needle
and circular aperture needle and in the center is the split-image/
microprism focusing aid. The area in between the upper and
lower right index marks is the proper exposure metering zone.
The upper mark doubles as battery check index. You simply
match the needles and the result will be the photograph you
want. With the AT-1's viewf inder, you see clearly just what you
will shoot and with your subject always in sight to give free rein
to your own creativity.

   To keep pace with fast action, a great Canon accessory, the
 porner winder A, will automatically advance the  f ilm at a rate of
 approximately two  f rames per second. To continuously advance
 the film, merely press the shutter release button. A succession of
 shots may then be taken under constant exposure conditions.
 Use of the Power Winder A minimizes film winding time and
 camera movement and gives maximum utilization of  all the
 AT-1's fantastic features.

 Continuous or Single Frame Shooting
   You can control shooting one or more frames at a time
 using the Power Winder A simply with your finger's pressure on
 the shutter release button. Since  f ilm advance  is automatic after
 every frame, this is very convenient. Shutter speeds for con-
 tinuous photography range from 1/60 to 1/1000 sec. and for
 single  f rame photography all shutter speeds can be used'
 Compact Design for Great Ease of Handling
    Weighing only 300g., even with batteries loaded. the Power
 Winder A is easy to carry and extremely fast and easy to mount.
 Its basic loaded battery pack A is designed for both convenience
 and balance in handling.

      To see just how automatic our match-needle AT-1 can get,
     try it out with the Speedlite 177A, for instance. Set the film
    speed on the 177A, turn the aperture ring to the aperture set
    on the 177A, turn the flash on and voila - you're ready to take
   a flash picture. Like the other A*eries Speedlites, the 177A
     automatically switches the shutter speed to the flash sync speed
     of 1/60 second as long as you don't have it set on "8".
        Special features of the 177A are a choice of two auto flash
     apertures and a wide adapter for covering the angle of a 28mm

   MACROLITE ML.I





     New on the scene, this two-headed flash is designed to provide
        the most appropriate distribution of light in close-up photography.
          It is made especially for the Canon FD 80-200mm f/4 lens and is
        also very useful with the FD 50mm f/3.5 Macroand FD 100mm
        f/4 Macro lenses.
     What does a non-macro zoom lens have to do with close-up
       photography? Combine the FD 8O-2O0mm   f 14 lens with the
       Macrolite and the new Close-up Lens 500T and watch it turn
       into a perfect solution for close-ups in the medical and dental
                   f ields. lts wide zoom range gives a wide range of close-up magnif  i-
        cations. And since the zoom range consists of long focal lengths,
          it's possible to keep a distance in delicate operations. lt's also
         f st and easy to use.
       Special features of the Macrolite include a wide adapter for

Canon's Unchallenged FD Lenses
    (D





       One of the best things about the AT-1 is the nearly fifty
     Canon lenses that go on it. lf you were always to use the same
         lens, most of the AT-1 's remarkable potential would go untapped.
      With a personal system of Canon lenses, you will get not only
       the most for your money but also the most fun out of an AT-1
         The right lens can make a certain picture possible, or easier, to
       take. lt can bring a far object closer or make a close subject seem
       farther away or make it appear almost exactly as it does in
        reality. lt can encompass the whole scene or only a very small
        part of it. With special lenses, it's even possible to make a round
        picture, magnify a small subiect or manipulate perspective.
        The AE-1 's best friends are Canon's nearly forty FD lenses.
      Each FD lens brings out the very best in the AE-1 and each
          is designed to make owning it an experience of pure joy.



                 lf a lens with afocal lengthof around 50 or 55mm is generally
       considered a normal lens because it results in a picture which
       looks closest to the scene you saw, any lens with a focal length
       below 50mm is a wide-angle  lens. A wide-angle lens takes in niore
       of a particular scene and makes objects within the scene smaller
      than does a normal lens from the same shooting distance. For
      sweeping landscapes and for fitting a large group of people in a
        picture indoors, this is the kind of lens to pull out of yourgrab
       bag. A good place to start looking for just the right one is with
       a 28mm lens, which is the most popular wide-angle focal length.

     It's easier to take pictures of sports and animals with a tele-
photo lens. lt's also much easier to grab shots of people without
their noticing. That's because a telephoto lens, like a telescope,
magnifies the subject, so whether by necessity or design, you can
shoot a subject from quite a distance and still fill the picture
with it. At the same time, you will automatically crop the picture
because a telephoto lens takes in less of the scene than does a
normal lens.
   Telephoto lenses are those which have a focal length longer
than 55mm. The longer the distance at which you usually shoot,
the longer the focal length you need. The 135mm focal length
 is very popular for its convenience and suitability in a wide
variety of typical situations.

   Once you've focused, you can actually change the focal length
of a zoom lens and still have your sublect in focus. Turning
a ring on the lens or pushing the lens in and out is all it takes to
zero in on your subject from an overall view. Or the other way
around. When you don't have time to move back and forth or
to change lenses to compose your picture exactly the way you
want it, only a zoom lens can do the trick. Be sure to check out
the FD 100-200mm f/5.6 lens. lts compactness, easy handling
and reasonable price make it a real winner.
