Canon EF100mm f-2.8L Macro IS USM Camera Lens Instructions

Canon EF100mm f-2.8L Macro IS USM Camera Lens

Thank you for purchasing a Canon product.
The Canon EF100mm f/2.8L MACRO IS USM lens is a macro lens dedicated to Canon EOS cameras. It is equipped with an Image Stabilizer and can shoot close-ups up to 1:1 as well as normal shots.

• “IS” stands for Image Stabilizer.
• “USM” stands for Ultrasonic Motor.

Features

1. The Image Stabilizer provides the effect of having a shutter speed about four stops faster during normal shooting.*
   This function provides optimal image stabilization depending on shooting conditions (such as shooting still subjects and following shots).

2. And with the vibration gyro and acceleration sensor, the image stabilization is highly effective even for close-up shots.

3. UD lens elements for excellent imaging performance.

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

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

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

7. A Canon macro flash makes it easy to take close-up pictures with a flash. The inner focusing mechanism enables AF photography while the macro flash is attached.

8. Tight seal structure ensures excellent dust-proof and drip-proof performance.

• Based on [1/focal length] second. To prevent blur caused by camera shake during normal shooting, the shutter speed should be the reciprocal of the current focal length (1/focal length) or faster.

  • Supplementary notes on using the lens and taking pictures.

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.

Mounting and Detaching the Lens

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

• 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 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.
• 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.

Setting the Focus Mode

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.

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

Switching the Focusing Distance Range

You can switch the focusing distance range to one of three settings: FULL (0.3 m/1.0 ft. to infinity), 0.3 m/1.0 ft. to 0.5 m/1.6 ft., or 0.5 m/1.6 ft. to infinity.
By setting the suitable focusing distance range, the actual autofocusing time can be shorter.

Infinity Compensation Mark

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 of subjects at infinity, look through the viewfinder or look at the magnified image* on the LCD screen while rotating the focusing ring.

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. The hood can be reverse-mounted on the lens for storage.

• 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.

Picture Taking

Normal Photography
The lens can be used as a medium-telephoto lens for normal photography such as portraits.
Closeup Photography
Close-up photos up to 1x (life-size) magnification 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. Although it depends on the shooting conditions, usually the shutter speed must be at least one or two stops faster than normal. 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.*

• Depending on shooting conditions.

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

• The magnification refers to the ratio between the subject’s size and the corresponding image size on the focal plane. On the distance index, it is indicated as 1:x.
• To check the depth of field, press the camera’s depth-of-field preview button.

About Exposure

Setting the Exposure
When taking photographs using TTL metering, no exposure compensation is necessary to meter the light coming through the lens. With TTL metering, AE (autoexposure) is possible at all focusing distances. Just set the desired picture-taking mode, then check the shutter speed and aperture before taking the picture.
Magnification and Effective f-number
The aperture displayed by the camera assumes that the focus is set to infinity. The actual aperture (effective f-number) becomes darker (effective f-number increases) at closer focusing distances (magnification increases). This does not cause exposure problems for normal picture-taking. However, for closeup photography, you cannot ignore the change in the effective f-number.

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

+  __1
2| +1| +1  1
      2| +2

• The correct exposure for a close-up shot largely depends on the subject. Therefore, try to bracket the exposure for the same subject.
• Using aperture-priority AE (Av) or Manual (M) picture-taking modes are recommended for macro photography as it is easy to adjust depth of field and exposure in these modes.

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).

1. Set the STABILIZER switch to ON.
   • If you are not going to use the image stabilizer function, set the switch to OFF.
   • When you press the shutter button halfway, 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 OFF when you are taking pictures using the Bulb setting (long exposures). If the STABILIZER switch is set to ON , 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.
• The Image Stabilizer consumes more power than normal shooting, so fewer shots can be taken if you use the function.
• The image stabilizer operates for about two seconds even when your finger is off the shutter button. Do not remove the lens while the stabilizer is in operation. This will cause a malfunction.
• With the EOS-1V/HS, 3, ELAN 7E/ELAN 7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN II/ELAN IIE/50/50E, REBEL 2000/300, IX, and D30, the Image Stabilizer will not work during self-timer operation.
• 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 shooting conditions, sometimes it may be better to turn off the Image Stabilizer function.
• The stabilizer is equally effective for hand-held photography and photography with a monopod.
• The image stabilizer function also operates when the lens is used with an Extension Tube EF12 ll or EF25 ll.
• Pictures may look distorted after being taken depending on the camera, but this doesn’t affect shooting.
• 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.

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:

• Hold the camera firmly
  As shown on the right, hold the camera firmly so 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.

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

1. 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.
2. With the collar open, remove the tripod mount.
3. 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.

Filters (Sold Separately)
You can attach filters to the filter mounting thread on the front of the lens.
