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. • Do not stand on the lens case. Falling off the case could result in injury.

1. 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.
2. Setting the Focus Mode 3. Switching the Focusing Distance Range 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. C Y P O You can set the focusing distance range at 6m/19.7ft. to infinity, 6m/19.7ft. - 20m/65.6ft., or 20m/65.6ft. to infinity.
4. Infinity Compensation Mark 5. Hood Infinity compensation mark Distance index 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. C For accurate manual focusing on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.
6. AF Stop Button • The AF stop function also works in AI Servo AF mode. • By setting the camera's Custom Function, you can change the AF stop button's function. For details, see the camera's instruction manual. During autofocus operation, you can press the AF stop button to temporarily pause autofocus. If the shutter button is still pressed halfway when the AF stop button is released, autofocusing will continue as before.
7. Focus Preset By presetting any focusing distance, you can instantly focus at that point even while you are shooting a different subject. This function operates in both the AF and MF modes. How to Focus at the Preset Distance While turning the playback ring to the left or right, press the shutter button completely. • The lens will focus at the preset distance. • If the focus preset switch was set to , the beeper will sound twice. C How to Set Set the focus preset switch to or .
8. Image Stabilizer Settings You can use the image stabilizer in AF or MF mode. Set the STABILIZER switch to . • If you are not going to use the image stabilizer function, set the switch to . Y P O Select the stabilizer mode. • MODE 1: Corrects vibrations in all directions. It is mainly effective for shooting still subjects.
9. Tips on Using the Image Stabilizer The image stabilizer in this lens is effective for hand-held shots or when using a monopod under the following conditions. ● MODE 1 ● MODE 2 C • In moderately dark areas such as evening scenes. • In locations where flash photography is prohibited such as live performances in theaters. • In situations where your footing is uncertain. • In situations where fast shutter settings cannot be used. Y P O • When panning subjects in motion.
Tips on Using the Image Stabilizer • 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 , the image stabilizer function may introduce errors. • The Image Stabilizer might not be fully effective in the following cases: • You shoot while riding on a bumpy road. • You move the camera dramatically for a panning shot in Mode 1.
