Thank you for purchasing a Canon product.
The Canon EF85mm f/1.2L II USM lens is a
high-performance medium telephoto lens
developed for EOS cameras. It is equipped
with a large-diameter, high-precision aspheric
lens element to achieve a brightness of f/1.2.
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.Features
1. Large-diameter, high-precision aspheric lenselement for excellent imaging performance
even at the maximum aperture.
2. Ultrasonic motor (USM) for quick and quiet autofocusing.
3. Electronic manual focusing detects electronically how much the focusing ring is
being rotated for manual focusing.
4. Manual focusing is available after the subject comes into focus in autofocus mode (ONE
SHOT AF).
5. A truly round aperture hole results in a nicer background blur.

aSafety Precautions
a Safety Precautions•Do not look at the sun or a bright light source
through the lens or camera. Doing so could result
in loss of vision. Looking at the sun directly through
the lens is especially hazardous.
• Whether it is attached to the camera or not, do
not leave the lens under the sun without the
lens cap attached. This is to prevent the lens from
concentrating the sun’s rays, which could cause a
fire.
Handling Cautions• If the lens is taken from a cold environment into
a warm one, condensation may develop on the
lens surface and internal parts. To  prevent
condensation in this case, first put the lens into an
airtight plastic bag before taking it from a cold to
wa rm  environment. Then take out the lens after it
has warmed gradually. Do the same when taking
the lens from a warm environment into a cold one.
• Do not leave the lens in excessive heat such as in
a car in direct sunlight. High temperatures can
cause the lens to malfunction.
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
Do not make any changes or modifications to the equipment
unless otherwise specified in the instructions. If such changes or
modifications should be made, you could be required to stop
operation of the equipment.
This equipment has been tested and found to comply with the
limits for a class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Consult the dealer or an experienced radio/TV technician for
help.
This Class B digital apparatus complies with Canadian ICES-003.

2.Setting the Focus Mode
¡After autofocusing in ONE SHOT AF mode, focusmanually by pressing the shutter button halfway and
turning the focusing ring. (Full-time manual focus)
¡However, full-time manual focus cannot be used under the following conditions.• When using the EOS 620, 650, 1000/1000F/REBEL/REBEL S, and
1000N/1000FN/REBEL II/REBEL S II.
• When taking photographs by setting the camera’s mode dial to Basic Zone modes.
To   shoot in autofocus (AF) mode, set the focus mode
swit ch to AF.
To   use only manual focusing (MF), set the focus mode
s witch to MF, and focus by turning the focusing ring.
See your camera’s instructions for details on
mounting and detaching the lens.
¡After detaching the lens, place the lens with the
rear end up to prevent the lens surface and
electrical contacts from getting scratched.
¡ If the contacts get soiled, scratched, or have
fingerprints on them, corrosion or faulty
connections can result. The camera and lens
may not operate properly.
¡ If the contacts get soiled or have fingerprints on
them, clean them with a soft cloth.
¡ If you remove the lens, cover it with the dust
cap. To attach it properly, align the lens mount
index and the 
Kindex of the dust cap as shown
in the diagram, and turn clockwise. To remove it,
reverse the order.
1.Mounting and Detaching the Lens
Do not touch the front rotating parts of the lens
while autofocus is active.

3.Infinity Compensation Mark
To  compensate for shifting of the infinity focus
point that results from changes in temperature.
The infinity position at normal temperature is the
point at which the vertical line of the L mark is
aligned with the distance indicator on the
distance scale.
F or accurate manual focusing on subjects at
infinity distance, look through the viewfinder while
rotating the focusing ring.
The infrared index corrects the focus setting
when using monochrome infrared film. Focus on
the subject manually, then adjust the distance
setting by moving the focusing ring to the
corresponding infrared index mark.
4. Infrared Index
Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
¡The infrared index position is based on a wav elength of 800 nm.
¡ Be sure to observe the manufacturer’s
instructions when using infrared film.
¡ Use a red filter also when you take the picture.

5. Depth-of-Field Scale
The depth of field is the distance in front of and
behind the plane of focus on the subject that
appears sharp. The depth of field is indicated by
the area between the depth-of-field scale lines
below the distance scale. Numbers in the scale
are in F values, and for example, if the shooting
distance is 5m and the aperture is f/11, the
sharp area will extend from about 4m to 7m.
The depth-of-field scale is an approximate
indicator.
6. Hood
The ES-79 II hood can keep unwanted light out
of the lens, and also protects the lens from rain,
snow, and dust.
Attach the hood using the following procedure.
¡While pressing the button on the back of thehood, push it against the hood mount of the
lens.
¡Release the button and place the claws of the hood in the groove on the hood mount.
The hood can be reverse-mounted on the lens
f or storage.
Pa rt of the picture may be blocked if the hood is
not attached properly.

7. Filters (Sold separately)
You can attach filters to the filter mounting thread
on the front of the lens.
¡Only one filter may be attached.
¡If you need a polarizing filter, use the Canon
Circular Polarizing Filter (72mm).
¡To   adjust the polarizing filter, first remove the
lens hood.
8.Extension Tubes (Sold separately)
Y ou can attach Extension Tube EF12 II or EF25
II for magnified shots. The shooting distance and
