Polaroid introduces sonar
focusing-the
ultimate
in

lost whi

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 sou nd
(1
,100 feet per
second).
The split second
it
takes for the
sound to reach your subject and
the echo
to
return
is
fed into a tiny
electronic computer inside the
camera.
The computer uses this time measurement 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 never waste 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 electronic flash statement
on
page
39.
