The Image Stabilizer reduces blur caused by camera shake approximately two full shutter speeds compared to normal handheld shooting. Features 1. The Image Stabilizer operates by moving optical elements inside the lens. Features include: • A special mode provided to obtain steadier viewfinder images during panning etc. • A switch turns the Image Stabilizer circuit on and off. 2. Two UD-glass elements suppress chromatic aberrations for sharp, high-contrast images expected of an L-series lens. 3. Ultrasonic Motor (USM) for quiet autofocusing. 4. Wide focusing ring makes manual focusing easy. 5. Minimum focusing distance of 1.5 m / 4.9 ft. 6. Compatible with Extender EF 1.4. ll and EF 2. ll. 7. The Image Stabilizer can be used while an Extender is attached (except with certain EOS cameras). : Warning to prevent malfunction or a flawed photo. : Helpful tips. ENG-2 a Safety Precautions (1) 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 can cause a fire. (2) Do not look at the sun or a bright light source through the lens or camera. Doing so can result in loss of vision. Looking at the sun through the detached lens is especially hazardous.

Align the lens mount index with the red dot on the camera. Then turn the lens clockwise until it locks in place. Remove the lens cap by pressing both clasps. ¦ Detaching the lens Hold down the lens release button on the camera and turn the lens counterclockwise until it detaches. 1.

To focus manually, set the focus mode switch to MF and turn the focusing ring. One of two focusing distance ranges can be set with the focusing limiter switch: 1.5 m - infinity or 3 m - infinity. 2. Setting the Focus Mode 3. Switching the Focusing Distance Range • Before switching the focusing distance range from 1.5 m - infinity to 3 m - infinity, first turn the focusing ring so that the distance scale index is within 3 m - infinity. • If the distance scale index is within 1.5 - 3 m and the focusing limiter switch is set to 3 m - infinity, initial autofocusing may cause the lens to first stop at 3 m on the distance scale. This is not a malfunction. If this occurs, press the shutter button again to resume normal autofocusing. AF MF m – – •1.5m – •3m – ENG-6 Full-time manual focusing enables you to focus manually even in the autofocus mode. Set the camera to One-Shot AF. After focus is achieved, hold down the shutter button halfway and turn the focusing ring to focus manually. 5. Full-time Manual Focusing 4. Macro Mechanism This lens is equipped with a macro mechanism for low magnification close-up photography. Autofocus function is also possible in the macro range as in normal shooting. If a picture with maximum magnification and minimum field of view coverage is required in the macro range, set the AF mode to manual, turn the manual focusing ring to the minimum focusing distance in the macro range. Then while looking through the viewfinder, move the camera (or your body) back and forth slowly until the image becomes clear. For the actual maximum magnification and minimum field of view 15 30 5 10 ft m values, please refer to the specifications. ENG-7 3) Using flash is undesirable.

The Image Stabilizer is effective with the following shutter speeds: ¦ Image Stabilizer Mode 2 Use this mode when panning a shot. It helps to steady the image in the viewfinder. Turn on (..) the Image Stabilizer switch. Set the Image Stabilizer Mode switch to 1 or 2. (For normal use, set to 1.) 6. Using the Image Stabilizer 1 2 Press the shutter button halfway to activate the Image Stabilizer. ¦ Image Stabilizer Mode 1 Image Stabilizer Mode 1 is especially effective in the following situations: 1) The subject is still. 2) The scene is dark such as at sunset or indoors. 3 STABILIZER MODE 1 2 STABILIZER I O ENG-8 • If the camera’s Custom Function is used to alter the AF activation method, the Ima...
