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.

ENG-2

aSafety 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.

ENG-3

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.

See your camera’s instructions for instructions on

mounting and detaching the lens.

•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.

•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

index of the dust cap as shown

in the diagram, and turn clockwise. To remove it,

reverse the order.

1. 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.

aPlease be careful when laying the lens sideways

while the lens hood and the lens cap are

attached.

The lens may roll and fall, resulting in injury.

ENG-6

3. Zooming

To zoom, turn the zoom ring.

Be sure to finish zooming before focusing.

Changing the zoom ring after focusing can affect

the focus.

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.

2. Setting 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

focus)

ENG-7

“C” and “H” Markings

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

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.

Zoom Limiter

The zoom limiter function allows for wide-angle

photos to be created when focus is set at infinity

without vignetting when using an EOS digital

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.”

Zooming

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).

ENG-8

• 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.

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.

Focal Length: 8mm

* 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

Approx. 10mm

APS-C

Diagonal Fisheye

Approx. 12mm

APS-H

Diagonal Fisheye Full Frame

Diagonal Fisheye

Approx. 15mm

•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.

ENG-9

Infinity Compensation Mark

Infinity compensation mark

Distance index

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.

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 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.

•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.

5. Infrared Index

Some EOS cameras cannot use infrared film. See

the instructions for your EOS camera.
