1. Mounting and Detaching the Lens

See your camera’s instructions for details 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.

• After detaching the lens, place the lens with the rear end up to prevent the lens surface and electrical contacts 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

Y 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

To shoot in autofocus (AF) mode, set the focus mode switch to AF.

COP regardless of the focus mode.

By setting the suitable focusing distance range, the actual autofocusing time can be shorter.

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

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 of subjects at

COP infinity, look through the viewfinder or look at the

Y magnified image* on the LCD screen while rotating the focusing ring.

* For cameras with Live View shooting capability.


5. Hood

The ET-73 hood can keep unwanted light out of the lens, and also protects the lens from rain, snow, and dust.


To attach the hood, align the hood’s attachment position mark with the red dot on the front of the lens, then turn the hood as shown by the arrow until the lens' red dot is aligned with the hood's stop position mark.


• Part of the picture may be blocked if the hood is not attached properly.

• When attaching or detaching the hood, grasp the base of the hood to turn it. To prevent deformation, do not grasp the rim of the hood to turn it.

• Remove the hood when using the macro flash.


6. Picture Taking

Normal Photography

The lens can be used as a medium-telephoto lens for normal photography such as portraits.

Since macro shots have a very shallow depth of field, focus carefully to obtain proper sharpness.

are possible. The minimum focusing distance of

30 cm is the distance from the subject to the focal plane. The working distance from the front of the lens to the subject is about 14 cm.

For normal close-up shooting, the higher the magnification, the faster the shutter speed must be to prevent blur caused by camera shake.

COP usually the shutter speed must be at least one or

For a shooting magnification of 0.5x, this lens provides the effect of a shutter speed faster by about three stops. For 1x, it will be about two stops faster.*

When you use a handheld exposure meter to set the exposure, you must take into account the exposure factor shown in the following table.

8. Image Stabilizer

You can use the image stabilizer in AF or MF mode.

This function provides optimal image stabilization depending on shooting conditions (such as shooting still subjects and following shots).


Set the STABILIZER switch to .

the Image Stabilizer will start operating.

• Make sure the image in the viewfinder is stable, then press the shutter button the rest of the way down to take the picture.

The image stabilizer in this lens is effective for hand-held shots under the following conditions.

• Close-up shooting.

• In semi-darkened areas such as indoors or outdoors at night.

• In locations where flash photography is prohibited, such as art museums and theater stages.

• In situations where your footing is uncertain.

• In situations where fast shutter settings cannot be used.

• When panning subjects in motion.


Image Stabilizer

• The shorter the subject distance from the camera, the lesser the Image Stabilizer effect will be.

• The Image Stabilizer cannot compensate for a blurred shot caused by a subject that moved.

• Set the STABILIZER switch to when you are taking pictures using the Bulb setting (long exposures). If the STABILIZER switch is set to ,

• When shooting a still subject, it compensates for camera shake in all directions.

• It compensates for vertical camera shake during following shots in a horizontal direction, and compensates for horizontal camera shake during following shots in a vertical direction.

• Using a tripod also stabilizes the image.

However, depending on the kind of tripod and the image stabilizer function may introduce errors.

• The Image Stabilizer may not be fully effective if you shoot from a violently shaking vehicle or other transportation.

D30, the Image Stabilizer will not work during self-timer operation.

• If you set the camera’s Custom Function to change the assigned button to operate the AF, the Image Stabilizer will operate when you press the newly assigned AF button.


9.Taking Hand-held Close-ups

Close-up shots are more prone to be affected by camera shake than with normal shooting. The

Image Stabilizer's corrective effect is therefore less during close-ups than during normal shooting even with the same degree of camera shake.

The depth of field also becomes very shallow with close-ups, and moving forward or back even slightly will throw off the focus.

When hand-holding the camera for close-up shooting, minimize camera shake and blurred focus with the following techniques:

Place both elbows on a steady surface such as a table.


Hold the camera firmly

it does not move while shooting.

Use AI Servo AF

For close-up shots, set the camera's AF mode to

AI Servo AF. Using autofocus is recommended.

The AI Servo AF mode can minimize blurred focus during close-up shooting.

For details, see the camera's instruction manual.

Use your knee to support an arm holding the camera.

Lean against a steady object like a wall.


10. Using the Tripod Mount

(Sold separately)

Adjusting the Revolving Mount

This lens can be used with the D (B) tripod mount ring, sold separately.

You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a particular camera model for switching between vertical and horizontal positions.


Use the following procedures to remove and attach the tripod mount.



With the collar open, remove the tripod mount.

Turn the locking knob counterclockwise until it becomes loose (about 3 turns), and pull the knob in the direction of the arrow to release the collar.

To install, while pulling the locking knob, bring the collar to the original position, and tighten the locking knob securely.

Depending on the EOS camera model, if a battery pack or vertical grip is attached, the tripod mount may bump into it. If that is the case, remove the battery pack/vertical grip or the tripod mount.

The tripod collar can be attached to or detached from the lens while the lens is attached to the camera.


11. Filters

(Sold Separately)

12. Extension Tubes

(Sold Separately)

You can attach filters to the filter mounting thread on the front of the lens.

You can attach Extension Tube EF12 II or EF25

II for magnified shots. The shooting distance and magnification are shown below.

• Filters and the macro flash cannot be used on this lens at the same time.


Distance (mm)


• If you need a polarizing filter, use the Canon
