6. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).

7. A truly round aperture hole results in a nicer
background blur.

8. Equipped with a zoom limiter function which
restricts the zoom range.

9. Tight seal structure ensures excellent dust­proof and drip-proof performance.

• "USM" stands for Ultrasonic Motor.

Thank you for purchasing a Canon product.

The Canon EF8-15mm f/4L Fisheye USM lens is
a high-performance fisheye zoom lens designed
for use with Canon EOS cameras.

Features

1. Designed for use with three different image
sensor sizes.

2. Aspherical and UD lens elements result in
outstanding image delineation.

3. SWC (Subwavelength Structure Coating) is
utilized to significantly reduce occurrences of
flare and ghost created by quite large incident
angles of light.

4. A fluorine coating has been applied to the
lens’s front and rear lens elements which
allows dust to be wiped from the outside of the
lens more easily compared with previous
lenses.

5. Ultrasonic motor (USM) for quick and quiet
autofocusing.

a Safety 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
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.

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.

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.
