TTL-SIR

PHASE DETECTION

AF
This
long
acronym
stands
for
Through
The
Lens-Secondary
Image
Registration
Autofocus.
It
refers
to
the
method
employed
by
EOS
(and
most
other
AF
SLRs)
to
detect
the
amount
of
defocus
at
the
film
plane.
A
simpler
way
of
saying
this
is
that
the
TTL-SIR
system
tells
the
camera
how
far
out
of
focus
the
lens
'
is,
and
in
what
direction.
Image-forming
light
first
passes
through
the
camera's
main
lens
to
the
semi-transparent
reflex
mirror.
Most
of
this
light
is
passed
to
the
camera's
viewfinder
for
the
photographer
to
see,
but
the
rest
of
it
is
diverted
to
the
AF
sensor
through
a
sub-
mirror
assembly.
At
the
bottom
of
the
mirror
chamber
is
the
opening
for
the
AF
sensing
device
(for
EOS,
the
BASIS
chip).
This
point
also
represents
the
geometric
equivalent
of
the
film
plane,
so
in
reality
the
BASIS
sensor
is
analyzing
a
"secondary"
image
which
is
created
at
this
position.
As
the
light
passes
through
the
AF
system,
it
hits
a
special
prism
that
divides
the
image
into
two
components
which
correspond
in
a
limited
way
to
the
top
and
bottom
halves
of
a
split-image
focusing
aid.
This
type
of
focusing
system
is
quite
common
in
manual-focus
SLRs.
Each
component
image
is
projected
onto
one
of
the
sensor
arrays
for
electronic
analysis.
As
long
as
there
is
a
discernible
level
of
contrast
in
the
analyzed
portion
of
the
image,
the
AF
system
can
calculate
the
degree
and
direction
of
defocus
almost
instantly,
resulting
in
a
digital
pUlse-count
instruction
to
the
lens
focusing
motor
through
the
control
circuitry
in
the
lens.
EOS
exceeds
all
other
AF
SLRs
in
the
maximum
amount
of
defocus
that
can
be
detected.
Upon
completion
of
lens
travel,
the
AF
detection
procedure
is
performed
again
immediately.
If
the
resulting
signal
indicates
that
the
subject
is
in
focus,
the
viewfinder
confirmation
signal
lights
up,
and
an
optional
beeper
is
activated.
If
the
AF
system
is
unable
to
find
a
discernible
level
of
contrast
after
one
complete
search,
lens
movement
is
stopped
and
the
AF
symbol
in
the
viewfinder
blinks
rapidly
as
an
indicator.

ULTRASONIC

MOTOR

(USM)

Canon's
ultrasonic
motor
is
a
ring-shaped
direct-drive
device
which
consists
of
a
stator
(a
stationary
element)
bonded
to
a
ceramic
element
and
a
rotor
(moving
element)
attached
to
the
focusing
component
of
the
lens
and
in
contact
with
the
stator.
When
voltage
with
a
frequency
of
20
kHz
or
higher
is
applied
to
the
ceramic
element,
the
vibrations
generated
by
the
ultrasonic
sound
produce
waves
which
continuously
advance
around
the
stator.
When
the
rotor
is
placed
in
contact
with
the
stator
under
pressure
from
a
washer
spring,
these
waves
apply
propulsion
to
the
rotor
and
make
it
turn.
