EF24-70mm f/4L IS USM C Y P O ENG Instructions
Thank you for purchasing a Canon product. Canon’s EF24-70mm f/4L IS USM is a highperformance standard zoom lens, for use with EOS cameras. The lens is installed with an Image Stabilizer, and allows for close-up shooting up to a magnification of 0.7x when the zoom ring is set to macro. ●● “IS” stands for Image Stabilizer. ●● “USM” stands for Ultrasonic Motor. Features Y P O 1. The Image Stabilizer provides the effect of having a shutter speed about four stops faster during normal shooting.
Safety Precautions Safety Precautions 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.
Safety Precautions This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Do not make any changes or modifications to the equipment unless otherwise specified in the instructions. If such changes or modifications should be made, you could be required to stop operation of the equipment.

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 dust- and water-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 Y P O To shoot in autofocus (AF) mode, set the focus mode switch to AF. To shoot in manual focus (MF) mode, 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 After autofocusing in ONE SHOT AF mode, focus manually by pressing the shutter button halfway and turning the focusing ring. (Full-time manual focus) 3. Zooming To zoom, rotate the zoom ring. Be sure to finish zooming before focusing.
4. 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. 1 Y P O Rotate the zoom ring to the widest position (24 mm). C 2 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.
5. Setting for Close-up Shooting Setting the zoom ring to macro allows for close-up shooting. 1 Slide the macro switch (zoom ring lock lever) to MACRO. Keep your finger on the lever so that it does not slide back to its normal position. Y P O 2 Rotate the zoom ring past the 3 Release the macro switch. telephoto end (70 mm) into the macro range indicated by the yellow line.
6. Close-up Shooting The yellow line on the distance scale indicates the range in which image degradation is minimal during close-up shooting.* The following procedure shows how to focus within the range indicated by the yellow line in order to capture photos with high definition. * However, maximum magnification is 0.5x when shooting within the range indicated by the yellow line on the distance scale. We recommend using a tripod for close-up (macro) shooting.
Close-up Shooting ●● Please focus carefully since the depth of field with close-ups is shallow. ●● The focusing ring distance scale is designed to display distances during normal shooting. As a result, it does not display distances during closeup shooting. ●● When the zoom ring is set to the macro range, there are cameras that will record the focal length information into the image at a value between the range from above 70 mm to 80 mm due to system issues.
7. Exposure during Close-up Shooting 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.
8. I nfinity 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 distance scale L mark is aligned with the distance index.
10. 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, following shots, and close-up shooting). ON 1 Set the STABILIZER switch to ON. ●● The Hybrid IS is activated during close-up shooting (see page 8) which provides highly effective image stabilization. ●● If you are not going to use the image stabilizer function, set the switch to OFF.
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.
11. Image Stabilization during Close-up Shooting 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. The magnification refers to the ratio between the subject’s size and the corresponding image size on the focal plane.
12. 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.
13. Hood The EW-83L hood cuts out unwanted light and protects the front of the lens from rain, snow, and dust. Y P O ●Attaching 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.
14. F ilters (Sold separately) 16. E xtension 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 PL-C B (77 mm). ●● To adjust the polarizing filter, first remove the lens hood. 15. C lose-up Lenses (Sold separately) C Attaching a 500D (77mm) Close-up Lens enables close-up photography. Magnification will be 0.05x – 0.29x. Magnification will be 0.16x – 0.
