ment gnerates, uses and can radiate radio frequency
enrgy and, if not installed and used in accordance with the
nstuctions, 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:
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 in
a warm one, condensation may develop on the
lens surface and internal parts. To preven
condensation in this case, first put the lens into an
airtight plastic bag before taking it from a cold to
warm 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.
• 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.

Precautions for Shooting with a Fisheye Lens
• If dirt or dust adheres to the surface of the front lens element, it can easily appear in images due
to the lens’s short focal length. In order to avoid this, please remove dirt or dust from the surface of
the front lens element by using a commercially available air dust blower.
• Since this lens has an extremely wide angle of view, light from bright light sources, such as the
sun, can easily enter the image area. Please do not look at bright light sources using the camera’s
viewfinder.
• Depending on shooting conditions, flare and ghost will ocur when bright light sources appear in
the image area. In order to prevent flare and ghost, we sggest shooting places such as shaded
areas so that bright light does not enter the lens.
• Unintentional photographing of the user’s ban easily occur during handheld shooting.
Likewise, the legs of a tripod can be unintey photographed when a tripod is used.
In addition, due to the optical charactristics ois lens, unintentional photographing of objects
can easily occur since the angle of view exeeds 180° in the close-up shooting range.
Therefore, please use the camera’s viewfinder or LCD display to carefully check the image area.
• Since this is an interchangeable lens, the center of the image circle of the circular fisheye and the
center of the image sensor are out of alignment. Also, there are times when vignetting, which
occurs in the four corners of an image, is not uniform.
• It is possible to use AE (Auto Exposure) even if vignetting occurs in the four corners of an image
when using a circular fisheye effect, etc. However, since the angle of view is extremely wide and
the luminance range of subjects is broad, we suggest changing the exposure manually when
possible.
Also, it is recommended that users check the image area using the LCD display when shooting
with a digital camera.

1. Mounting and Detaching the Lens
See your camera’s instructions for instructions on
mounting and detaching the lens.
The lens mount has a rubber ring for enhanced
water- and dust-resistance. The rubber ring may
cause slight abrasions around the camera's lens
mount, but this will not cause any problems. If the
rubber ring becomes worn, it is replaceable by a
Canon Service Center at cost.
Plase be careful when laying the lens sideways
we the lens hood and the lens cap are
attahed.
a
• After detaching the lens, please attach the lens
hood and lens cap and place the lens with the
rear end up to prevent the electrical contacts
and lens surface from getting scratched
• If the contacts get soiled, scratched, or ave
fingerprints on them, corrosion or faulty
connections can result. The camera and lens
may not operate properly.
The lens may roll and fall, resulting in injury.
• 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
K
index of the dust cap as shown
in the diagram, and turn clockwise. To remove it,
reverse the order.

To use only manual focusing (MF), set the foc
mode switch to MF, and focus by turning the
focusing ring. The focusing ring always works
regardless of the focus mode.
After autofocusing in ONE SHOT AF mode, focus
manually by pressing the shutter button halfway
and turning the focusing ring. (Full-time manual

to between 10mm and 15mm, then slide the
switch towards “LIMIT.”
When the “C” / ”H” indicator above the focus ring
is aligned with either the “C” or “H” marking, there
are times when vignetting occurs in the corners of
an image since the size of the image circle
becomes smaller when the focus position is set at
close range due to the optical characteristics of
this lens.
The zoom limiter cannot be used if the zoom ring
is set between 8mm and about 10mm (when the
“C” / “H” indicators on the zoom ring are set
between the “C” indicator and the wide-angle
direction on the ring next to the zoom ring).

* The circle corresponding with each focal length indicates a 180 degreof viein the imaging area.
* Vignetting occurs in the area outside of the image circle.
• Circular Fisheye
The circular fisheye effect refers to the 180 degree ciular anew which appears within the area of the image sensor. When the
focusing distance of this particular lens is set to infini, the circulisheye effect is achieved by setting the focal length (wide end) to
8mm and using a camera equipped with a full frame iage snsor.
• Diagonal Fisheye
The diagonal fisheye effect refers to a 180 degree diagonal angle of view which corresponds with the size of the sensor. When the
focusing distance of this particular lens is set to infinity, the diagonal fisheye effect is achieved by setting the focal length (telephoto
end) to 15mm when used with full frame image sensors, approximately 12mm when used with APS-H, and approximately 10mm when
used with APS-C.
• Use of the zoom limiter at the lens’s wide end position does not guarantee that a diagonal fisheye effect will be
created when used with APS-C sensors.
• When the focusing distance is set to infinity, the angle of view when using the lens set at the telephoto end together
with full frame format cameras is 175°30’ (diagonal). The 180° diagonal fisheye effect is achieved by slightly turning
the zoom ring toward the wide end when the lens is set at 15 mm (telephoto end).
• Due to the optical characteristics of the lens, the size of the image circle becomes smaller when the focus position
is set at close range.

4. Infinity Compensation Mark
5. Infrared Index
Infinity compensation mark
Distance index
The infred index corrects the focus setting when using
mnochrme infrared film. Focus on the subject
ually, then adjust the distance setting by moving the
fousing ring to the corresponding infrared index 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.
Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
For accurate manual focusing on subjects at
infinity distance, turn the focus ring while looking
through the viewfinder or checking the camera’s
LCD display.
• The infrared index position is based on a
wavelength of 800 nm.
• The compensation amount differs depending on
the focal length. Use the indicated focal length
as a guide when setting the compensation
amount.
• Be sure to observe the manufacturer’s
instructions when using infrared film.
• Use a red filter also when you take the picture.
