SELLING POINTS
The new F-1
is
Canon's top-of-the-line
professional
camera.
It is introduced
as
the
successor
to
the original
F-1
which, since its introduction
in 1971,
has
become
the
mainstay
system
camera for
growing numbers
of
profes-
sional photographers
in
all
fields
.
Continuing the unmatched tradition
of
durability
and
reliability
established
by its predecessor, the new F-1 will
function
perfectly
for
a minimum of
100,000
exposures.
It has
successfully
undergone
a
demanding
series
of
vibration,
shock and operation
tests
as
well
as
temperature testing between
-30°C (-22 °F)
and
+60°C
(140°F).

dust and moisture from
locations
such as

and

parts. And the
shutter curtain control
magnets
are Silver-plated
to ensure
better contacts and
longer life
cycle.
Elastic
connectors
instead
of solder

are used to connect the
main
PC board to the resistor
board
and
other flexible circuit
boards pro-

the
other a
digital
control
circuit which controls the
shut-
ter
speed,
electromagnetic
release,
self-timer and exposure meter. These
circuits also monitor the
contro
l
status
of
both the
camera
and its accesso-
ries
.
The
"Check and
Go"
system of
electro-mechanical
sequences checks
each
camera operation
and function to
determine whether
it
was normal
or
not before passing to the next stage.
"Check and
Go" is
executed
in three
steps:
prior to shutter button release,
prior to making exposure after first
press
of
the shutter button and prior to
winding the film to next frame in
con-
tinuous shooting.
The new F-1 has two IC's, one for the
photometry
circuit
with an analog op-
erationa
l
amplifier
to
perform
exposure
calculations
based
on
the subject il-
lumination,

speed,
aperture

Contributing to this
impressive
record
are
several revolutionary advances
in
production
technology.
These include
the
computer-controlled
NC
(Numer-
ical
Control) machine which performs
a variety
of
grinding,
milling
and drill-
ing
functions,
primarily
on
the die-cast
body and AE Finder FN. The
machine
is also
used for precision milling
of in-
dividual parts. Other
advances
include
the use
of
laser welding
instead of
conventiona
l
rivets,
and
burnishing
of
the inner
surface
of
shafts
by forcing
ball
bearings
through
under
high
pneumatic pressure.

Metering Circuit:
Slight pressure
on
the
shutter button turns on
the metering

pOSition,
slight
pressure
on
the
shutter
button turn
s
on
the
circuit and metering
remains
on
for

without
maintaining pressure
on
the
shutter
button,
and
then turns
itself
off, or
turns
off earlier with shutter release
.
