EF70-200mm f/4L IS USM ENG Instruction
Thank you for purchasing a Canon product. The Canon EF70-200mm f/4L IS USM lens is a lightweight, compact, high-performance telephoto zoom lens with an Image Stabilizer for EOS cameras. • "IS" stands for Image Stabilizer. • "USM" stands for Ultrasonic Motor. Conventions used in this instruction Warning to prevent lens or camera malfunction or damage. Supplementary notes on using the lens and taking pictures. Features 1.
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.

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 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. 3. Switching the Focusing Distance Range You can set the focusing distance range to 1.2 m/3.9 ft. to infinity or 3 m/9.8 ft. to infinity. By setting the suitable focusing distance range, the actual autofocusing time can be shorter.
4. Zooming To zoom, turn the zoom ring. Be sure to finish zooming before focusing. Zooming after focusing can affect the focus. 5. Hood The ET-74 hood can keep unwanted light out of the lens, and also protects the front of the lens from rain, snow, and dust. Attach and align the hood to the hood mount on the front of the lens, and turn the hood as shown by the arrow to secure it. The hood can be reverse-mounted on the lens for storage.
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 . 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 • 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. when you are • Set the STABILIZER switch to 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 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 on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.
10. Using the Tripod Mount (Sold separately) Adjusting the Revolving Mount This lens can be used with the A II (W) 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 (Sold separately) You can attach filters to the filter mounting thread on the front of the lens. 12. Extension Tubes (Sold separately) You can attach Extension Tube EF12 II or EF25 II for magnified shots. The shooting distance and magnification are shown below. • If you need a polarizing filter, use the Canon Circular Polarizing Filter (67mm). • To adjust the polarizing filter, first remove the lens hood.
13. Extenders (Sold separately) With Extender EF1.4X ll or EF2X ll attached, the lens specifications will change as follows: Item With EF1.4X ll Extender With EF2X ll Extender Focal length (mm) 98 – 280 140 – 400 Aperture f/5.6 – 45 f/8 – 64 25°20’ – 8°50’ 16°20’ – 6°10’ Diagonal Angle of view Vertical 13°50’ – 4°55’ 9°10’ – 3°30’ Horizontal 20°50’ – 7°20’ 13°40’ – 5°10’ 0.31 0.45 Maximum magnification (×) • First attach the Extender to the lens, then attach the lens to the camera.
