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 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  
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 occur when bright light sources appear in  
the image area. In order to prevent flare and ghost, we suggest shooting places such as shaded  
areas so that bright light does not enter the lens.  
• Unintentional photographing of the user’s body can easily occur during handheld shooting.  
Likewise, the legs of a tripod can be unintentionally photographed when a tripod is used.  
In addition, due to the optical characteristics of this lens, unintentional photographing of objects  
can easily occur since the angle of view exceeds 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.  
Please be careful when laying the lens sideways  
while the lens hood and the lens cap are  
attached.  
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 have  
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.

3. Zooming  
To shoot in autofocus (AF) mode, set the focus  
mode switch to AF.  
To use only manual focusing (MF), set the focus  
mode switch to MF, and focus by turning the  
focusing ring. The focusing ring always works,  
regardless of the focus mode.  
To zoom, turn the zoom ring.  
Be sure to finish zooming before focusing.  
Changing the zoom ring after focusing can affect  
the focus.  
After autofocusing in ONE SHOT AF mode, focus  
manually by pressing the shutter button halfway  
and turning the focusing ring. (Full-time manual

Zooming  
“C” and “H” Markings  
Zoom Limiter  
The zoom limiter function allows for wide-angle  
photos to be created when focus is set at infinity  
Adjacent to the zoom ring, the “C” and “H”  
markings serve as guides to indicate the wide-  
angle zoom position where focus is set at infinity without vignetting when using an EOS digital  
at which photos can be created without  
vignetting when using EOS digital cameras  
installed with APS-C or APS-H image sensors.  
The “C”/”H” indicator on the zoom ring is aligned  
with either the “C” or “H” marking.  
camera installed with an APS-C image sensor by  
limiting the zoom range.  
Activate the zoom limiter by setting the zoom ring  
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).

Description of Fisheye Lens Based Photography  
The various images below show the different relationships between the fisheye lens’s 180 degree angle of view and the size  
of each image sensor related to focal length.

* The circle corresponding with each focal length indicates a 180 degree angle of view in the imaging area.  
* Vignetting occurs in the area outside of the image circle.  
• Circular Fisheye  
The circular fisheye effect refers to the 180 degree circular angle of view which appears within the area of the image sensor. When the  
focusing distance of this particular lens is set to infinity, the circular fisheye effect is achieved by setting the focal length (wide end) to  
8mm and using a camera equipped with a full frame image sensor.  
• 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 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.  
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.
