Thank you for purchasing a Canon product.
The Canon EF50mm f/1.2L
USM
lens
is
a
high-performance, large-aperture standard
lens
with
a large-diameter, high-precision,
aspherical lens element designed
for
EOS
cameras.
The lens
is
suitable
for
portraits
and
other
types
of
photographs
making full use
of
the
large-diameter lens feature
for
nice
background blur.
• "USM" stands for Ultrasonic Motor.
Conventions used in

Warning to prevent lens or
camera
malfunction or damage.
Features
1.
Large-diameter, high-precision aspheric lens
element for excellent imaging performance
even at the maximum aperture.
2.
Ultrasonic motor (USM) for quick and quiet
autofocusing.
3. Manual focusing is available after the subject
comes into focus
in
autofocus mode (ONE
SHOT AF).
4.
A truly round aperture hole results
in
a nicer
background blur.
5.
Tight seal structure ensures excellent dust-
proof and drip-proof performance.
• Since the
front
element
of
this
lens moves when
focusing, you need
to
attach a Canon PROTECT
filter sold separately
for
adequate dust-and
water-resistant performance. Without a filter, the
lens is
not
dust
or
water resistant.
Supplementary notes on using the lens
and taking pictures.
