The lens also has a second image stabilizer mode that is optimized for following shots of moving subjects. 2.
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. • Do not point the lens or camera at the sun or photograph it. This is because the lens concentrates the sun’s rays even when the sun is outside the image area or when shooting with backlight, which could cause malfunction or fire.

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.
2. Setting the Focus Mode 3. Zooming Y P O To zoom, turn the zoom ring. 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 Be sure to finish zooming before focusing. Zooming after focusing can affect the focus. Especially for shooting distances shorter than 3 m / 9.8 ft.
4. Hood The ET-73B hood can keep unwanted light out of the lens, and also protects the lens from rain, snow, and dust. Y P O 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. C • Part of the picture may be blocked if the hood is not attached properly.
5. Fixing the Zoom Ring The zoom ring can be fixed to keep the lens at the shortest point. This function is convenient for carrying a camera on a strap because it prevents the lens from extending. Y P O Turn the zoom ring to the widest position (70mm). C Slide the zoom ring lock lever in the direction indicated by the arrow. • To release the zoom ring, slide the zoom ring lock lever in the direction opposite to the arrow. The zoom ring can only be locked at maximum wide angle.
6. 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.
7. Tips on Using the Image Stabilizer The image stabilizer in this lens is effective for hand-held shots under the following conditions. ● MODE 1 ● MODE 2 C Y P O • 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.
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.
8. Infinity Compensation Mark 9. Infrared Index Infinity compensation mark Distance index Y P O 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.
10. Using the Tripod Mount (Sold separately) Adjusting the Revolving Mount This lens can be used with the C (W II) 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.
11. Filters 12. Extension Tubes (Sold separately) You can attach filters to the filter mounting thread on the front of the lens. • If you need a polarizing filter, use the Canon Circular Polarizing Filter (67mm). • To adjust the polarizing filter, first remove the lens hood. (Sold separately) You can attach Extension Tube EF12 II or EF25 II for magnified shots. The shooting distance and magnification are shown below.
