optics
does
Canon
utilize
to
correct
for
chromatic
aberrations
in

lenses?
A)
Aspheric
optical
construction.
B)
Fluorite
and
Ultra-low
dispersion
(UD)
glass.
C)
ED
glass.
D)
EMD
-
Electro-magnetic
diaphragm.
E)

employs
which
of
the
following
information
processing
systems?
A) A
single
dedicated
super-microprocessor
for

Canon
is
the
only
manufacturer
to
utilize
this
unique
auto-
focusing
sensor
necessary
for
achieving
speedy
focusing
and
high-sensitivity
under
low-light
conditions.
The
sensor
is:
A)
CCD
-
Charge-Coupled
Device.
B) BASIS -
Base-Stored
Image
Sensor.
C)
AlA -
Active
Infrared
Autofocus.
D)

-
Autofocus
Sensor.
8.
BASIS
was
created
to
meet
the
autofocusing
needs
of
professional
photographers?
How
does
BASIS
accomplish
this?
A)
Preserves
signal
integrity
by
amplifying
the
electrical
signals
before
they
are
read
out
through
switching.
B)
Equipped
with
an
extra
circuit,
it
boosts
the
signal
ten
times
in
order
to
improve
sensitivity
and
SIN
ratio.

C)
Using
two
47-bit
hor,izontal
and
two
29-bit
vertical
line
sensors.
D)
All
of
the
above.
