EF14mm f/2.8L II USM





Thank you for purchasing a Canon product.


The Canon EF14mm f/2.8L II USM is a highperformance super wide-angle lens designed for EOS cameras.

¡ “USM” stands for Ultrasonic Motor.

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

2. Ultrasonic motor (USM) for fast, quiet focusing.

3. Manual focusing is available after the subject comes into focus in autofocus mode (ONE Y

4. Close-up photography up to 0.2 m/0.7 ft.

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

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

Supplementary notes on using the lens and taking pictures.


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

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.

1. Mounting and Detaching the Lens

See your camera’s instructions for details on mounting and detaching the lens.

See the diagrams below for directions for removing and attaching the lens cap.

¡ After detaching the lens, place the lens with the rear end up to prevent the lens surface and electrical contacts from getting scratched.


The lens mount has a rubber ring for enhanced

¡ If the contacts get soiled, scratched, or have fingerprints on them, corrosion or faulty connections can result. The camera and lens

¡ If the contacts get soiled or have fingerprints on Canon Service Center at cost.

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.


2. Setting the Focus Mode 3. Infinity Compensation Mark

After autofocusing in ONE SHOT AF mode, focus manually by pressing the shutter button halfway and turning the focusing ring. (Full-time manual focus)

For accurate manual focusing on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.


4. Infrared Index 5. Depth-of-Field Scale

The infrared index corrects the focus setting The depth of field is the distance in front of and when using monochrome infrared film. Focus on the subject manually, then adjust the distance setting by moving the focusing ring to the behind the plane of focus on the subject that Y the area between the depth-of-field scale lines corresponding infrared index mark.

Some EOS cameras cannot use infrared film. See below the distance scale. The numbers on the COP shooting distance is 0.5m and the aperture is the instructions for your EOS camera.

f/16, the area in focus will extend from about

0.3m to infinity.

¡ The infrared index position is based on a wavelength of 800 nm.

¡ Be sure to observe the manufacturer’s instructions when using infrared film.

¡ Use a red filter also when you take the picture.

The depth-of-field scale is an approximate indicator.


6. Filter Holder

There is a gelatin filter holder at the rear of the lens. Cut the gelatin filter to fit within the white frames. Then insert the gelatin filter into the filter holder.

¡ Only one filter can be used.

¡ When you use a gelatin filter, ghosting may


Y appear in the image.
