Precautions to ensure that the camera is used safely. Read these precautions thoroughly. Make sure all details are observed in order to prevent risks and injury to the user and other people.
Be sure to follow the instructions carefully when using the lens.
- Do not look directly at the sun or other strong light sources through a lens. This may result in loss of sight.
- Do not leave a lens in the sun without the lens cap attached. The lens may concentrate on entering sunlight and cause a malfunction or fire.
- Do not leave the product in places exposed to extremely high or low temperatures. The product may cause burns or injury when touched.
- Do not shoot movies with extreme movement. Viewing such movies may result in motion sickness-like symptoms.
- Avoid shaking while shooting. Viewing VR images taken while riding a vehicle or walking may result in feelings of fatigue or discomfort. When shooting such images, the use of a tripod is recommended. Use the tripod to create a level view before shooting.
Be sure to follow the instructions carefully when viewing VR images.
- Those with an eye or heart condition or high blood pressure, pregnant women, and those with a history of spine disorders should consult with a doctor before viewing. Viewing such images may cause symptoms to worsen.
- Some individuals may experience muscle spasms, loss of consciousness, seizures, or other such symptoms while being subjected to stimuli such as bright lights or repeatedly blinking images. If you have ever experienced these sorts of problems, be sure to consult with a doctor before viewing. Viewing such images may cause symptoms to worsen.
- Extended continuous viewing the images by a person who has not yet finished developing may adversely affect the eyes or body. Please pay attention to the user’s condition when viewing by anyone age 15 or younger. If you notice that the person has an abnormal physical condition, immediately stop using this device and see a doctor. Please use this device continuously for no longer than 3 minutes.
- Those who cannot see the images clearly should refrain from viewing them. This may adversely affect the eyes or body.
- Viewing the images by those who are unwell is not recommended. This may cause feelings of nausea.
- Those who are susceptible to motion sickness should consult with a doctor before viewing. Viewing may cause the same symptoms to occur.
- Do not view continuously for more than 30 minutes and allow your eyes and body to rest periodically. Extended continuous viewing may adversely affect the eyes or body.
- If you start to feel fatigued, discomfort, or any abnormality while viewing, discontinue viewing. Continued viewing may affect your health.
- Do not view images with either left or right display blocked, or while otherwise viewing drastically different images on the left and right sides. This may have a negative effect on the eyes or body.
- Do not leave the product in excessive heat such as in a car in direct sunlight. High temperatures can cause the product to malfunction.
- 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.
- Please also read any lens-related handling precautions listed in your camera’s instruction manual.
- This lens has a short focal length, which means dirt or dust on the surface of the lens will show up easily. Use a commercially-available blower to remove dirt or dust from the lens surface or mount opening.
- Since this lens has a wide-angle and the tip of the lens protrudes forward, the adjacent lens will appear in the image.
- When shooting hand-held shots, be careful that your body does not appear in the image. And when using a tripod, be careful that the leg of the tripod does not appear in the image.
- This lens is comprised of two lenses, and both the left and right lenses are read by one sensor. Depending on the camera, the image of the left lens is displayed on right side of the monitor, and the image of the right lens is displayed on the left side of the monitor. Please refer to the camera’s instructions for details.

Attaching and Detaching the Lens
Attaching the Lens
Align the lens mount indexes of the lens and camera, and turn the lens clockwise until you hear a click.
Detaching the Lens
Turn the lens counterclockwise while pressing the camera’s lens release button. Detach the lens once it has stopped turning.
Please refer to the camera’s instructions for details.
- Set the camera’s power switch to OFF when attaching or detaching the lens.
- Attach the lens cap before detaching the lens from the camera.
- After detaching the lens, place the lens with the rear end up and attach the dust cap to prevent the lens surface and contacts from getting scratched. Make sure the lens and dust cap mount indexes are aligned when attaching the dust cap.
- Contacts that are scratched, soiled, or have fingerprints on them may result in faulty connections or corrosion, which may lead to malfunctions. If the contacts get soiled, clean them with a soft cloth.
- The lens mount has a rubber ring to improve dust resistance and water-resistance performance. This rubber ring may cause friction marks to appear around the camera’s lens mount, although this will have no effect on usage.
- Rubber rings can be replaced at Canon Service Center. (chargeable)

- This lens does not have a depth-of-field scale. Focus using the camera’s Live View image.
- The focusing ring setting direction cannot be reversed for this lens.
- MF operation sensitivity cannot be changed with this lens.
- Focus may drift if the focusing ring is touched during use.
- Turn the left-right focus difference adjustment dial to adjust the focus if there is a difference in focus between the left and right lenses.
Checking/adjusting left and the right focus
Checking Left and Right Focus
When first mounting this lens on the camera, or when using it after being transported for an extended period, use the following steps to check the difference between left and right focus.
- Display an enlarged image from the left lens, then turn the focusing ring to focus the lens.
- Press the <B> button on the camera to switch to an enlarged image from the right lens.
- If the focus in the enlarged image from the right lens is correct after switching, adjustment is not needed. Only adjust the focus, using the steps on the following page, if the focus is not correct.
Displaying an enlarged image from the left lens.
- Pressing the <
> button on the camera allows you to change the enlargement ratio of the image from the left lens.
- Pressing the <INFO> button on the camera allows you to switch the display of enlarged images between the left and right lenses. Refer to the camera’s instructions for further details.
Checking/adjusting left and right focus
Adjusting left and right focus
Leaving the enlarged image from the right lens showing, adjust using the following steps.
Detach the cap.
• Remember to firmly attach the cap after adjustment.
- Use the included hex key to turn the left-right focus difference adjustment dial to adjust focus.
- Turning the left-right focus difference adjustment dial only adjusts the focus of the right lens.
- Adjustment is complete once the focus in the enlarged image from the right lens is correct.
Filters (Sold separately)
This lens has a gelatin filter holder at the rear. Cut the filter to the size that will fit in the filter index, and insert it into the holder.
- Cut the gelatin filter.
• The recommended size for the filter is 20mm high by 36mm wide.
• Cut off the corners before using.
- Insert the gelatin filter into the holder from the right side.
- Check if the gelatin filter is correctly inserted (whether it is within the frame, whether a corner is projecting out, etc.).
• If the filter projects outside, cut the corner.
• Only one filter may be used.
• Image ghosting may occur as a result of using a gelatin filter. Take care to avoid getting dirt or scratches on the gelatin filter.
Photographing with AE (auto exposure) is possible at all focusing distances even with this lens attached.
- AE metering range is restricted to within the image circle in the left lens.
- As this lens is wide-angle, using flash photography on close-up subjects can cause very inaccurate AE exposure measurements. In that case, either uses a separate light meter or check your images after capture.
