focusing-the ultimate in
one-step photography
That unexpected moment, that
periect smile,

lost whi
Ie you pause to set the lens.
The instant you see your picture,
just aim and shoot. With sonar
focusing, the camera sets the lens
instantly,automatically.
Now, nothing interieres with seeing
the shot and taking it.
(See "How sonar focusing works"
inside this foldout.)

How sonar focusing works
As you beg in to press the shutter
button, your camera releases sound
waves to the central part of the scene
(approximate area marked
in blue).
The frequencies are far beyond our
range of hearing and travel at the
speed of sound
(1 ,100 feet per
second).
The split second it takes for the
sound to reach your subjectand
the echo
to return is fed into a tiny
electronic computer inside the
camera.
The computer uses this time mea-
surement to calculate the distance
between the camera lens and your
subject, then signals a motor to turn
the lens until your subject
is in
sharp focus.
This extraordinary chain of events
takes
place in less than 113 of a
second.

POLAROID SX ·70 LAND FILM
Film and flash
Your camera uses Polaroid SX-70
Land film and FlashBars. Each film
pack provides ten color pictures
and contains a battery that powers
the camera. Each FlashBar has
ten bulbs.
You'll neverwaste a flash or film
with this camera.
It will not let a
bulb fire when a film pack is empty
and will not take a picture when
all the bulbs on one side of the
FlashBar have been fired. Your
camera also finds the next good
bulb in a partly used FlashBar.
Please read the important elec-
tronic flash statement
on page 39.
