Turn the locking collar as shown by the arrow and tighten. (The mounting foot's locking pin will extend into the hot shoe.) * To detach the Speedlite. turn the locking collar in the opposite direction until it stops. (The locking pin retracts into the mounting toot.
4. Wireless Selector The wireless selector has three settings as shown below. Set to OFF to use the 550EX as a normal, on-camera Speedlite. |oFn*r SLAVE VASTER Set to MASTER to use the 550EX as the master unit in a wireless, multi-Speedlite system. •I* OI Ayg MASTER Set to SLAVE to use the 550EX as £ slave unit in a wireless, multi-Speedlite system.
Wireless Selector If the 550EX is to be used as a normal, on-camera Speedlite but the wireless selector has been set to MASTER or SLAVE, the following applies: MASTER : If master flash ON has also been set, it will be the same as using the Speedlite at the wireless selector's OFF setting. If master flash OFF has been set, a picture cannot be taken. SLAVE : It will be the same as using the Speedlite at the wireless selector's OFF setting. However, when the camera's exposure meter turns off 6 sec.
5. Main Switch The main switch has three settings as shown below. 1 (C lio o/T) Turns off the power. /-SE (C ( Turns on the power. rSE U) 1 (( 3 O-v Turns on the power and enables the SE mode. • The SE (Save Energy) mode turns off the Speedlite automatically after a period of non-use as indicated in the following table. Wireless Selector Setting OFF 1 MASTER SLAVE 90 sec. 60 min. When the wireless selector is set to (§H) or MASTER and the SE mode takes effect, the LCD panel display turns off.
6. Pilot Lamp and Test Firing the Speedlite’s main switch to I . 1 •Set The flash will start charging. When the flash Is ready, the pilot lamp lights. • Red pilot lamp When the flash is fully charged, the pilot lamp lights in red. For normal use, confirm that the pilot lamp is red before taking the picture. • Yellow pilot lamp When the camera is set for single shooting, a yellow pilot lamp indicates a less-than-full charge which enables a quick flash (see description below).
7. Flash Exposure Confirmation When a correct flash exposure has been obtained, the flash exposure confirmation lamp on the back of the Speedlite lights in yellow-green for 3 sec. If the flash exposure confirmation lamp does not light after the flash fires, the picture may have been underexposed. Move closer to the subject and try again. 8.

To turn off the illumination, press the <:6.;> button again. 0.S 0.
12. AF-Assist Beam In low-light or low-contrast situations, the Speedlite emits the AF-assist beam automatically to assist autofocusing. The AF-assist beam is compatible with the EOS-3's area AF and EOS-1 N’s five focusing points. The AF-assist beam is effective with 28mm and longer lenses. Its effective range in darkness is indicated in the table below. See page 123 for details on when the AF-assist beam is emitted. Position Effective Range Center Approx. 0.6 -10 m / 2 ■ 33 ft. Periphery Approx. 0.
For Type-A Cameras Basic Flash Photography When the Speedlite 550EX is attached to a Type-A camera such as the EOS3 , you can take flash pictures with E-TTL autoflash as easily as normal autoexposure (AE) pictures. As with evaluative metering, the E-TTL autoflash system uses a multi-zone sensor. A preflash is fired for evaluative flash metering and the reading is stored in memory. Since E-TTL autoflash is linked to the active focusing point, the flash exposure is highly accurate.
1. Using Flash in Full Auto Mode Set the camera’s picture-taking mode to P (Program AE) or D (Full Auto). Flash photography will then be as easy as normal AE photography. The camera sets the aperture and shutter speed automatically to suit a wide variety of lighting conditions including outdoor fill flash. The E-TTL autoflash system sets the flash exposure automatically. ■I Set the camera’s picture-taking mode ' toP. Zoom Summ ETTL Set the 550EX’s flash mode to ETTL. Focus the subject. O.S 0.
Using Flash in Full Auto Mode After the flash fires, check that the flash exposure confirmation lamp lights. When a correct flash exposure has been obtained, the flash exposure confirmation lamp lights for about 3 sec. If the lamp does not light, the flash may have been insufficient, resulting in underexposure. In such a case, check that the pilot lamp is red, then move closer to the subject and take the picture again. 3 • The preflash is fired to obtain an evaluative flash meter reading.
2. Using Flash in Other Camera Modes Flash photography is also automatic in the other picture-taking modes. In the Av (aperture-priority AE), Tv (shutter speed-priority AE), and M modes, the E-TTL autoflash system sets the flash exposure automatically. The camera sets the necessary shutter speed (in the Av mode), aperture (in the Tv mode), or flash output (in the M mode). Flash photography is as easy as normal AE picture-taking.
Using Flash in Other Camera Modes (1) Av: Aperture-Priority AE and E-TTL Autoflash This mode is effective for controlling the depth of field in your flash pictures. You can also obtain a balanced exposure betw/een the subject and background. You set the aperture and the camera sets the shutter speed automatically to obtain a correct exposure for the background. The E-TTL autoflash system obtains the proper exposure based on the aperture you set. ■I Set the camera’s picture-taking mode ' to Av. O.S 0.
Using Flash in Other Camera Modes • Balanced Flash Exposures In low-light situations, the exposure levei can be baianced between the subject and background by using a siow sync speed. You can obtain balanced flash exposures automatically by setting the camera's picture-taking mode to Av. The camera then sets the sync speed automatically to suit the background. Using a tripod is recommended to prevent camera shake. The image was removed due to copyright restrictions Balanced flash exposure.
Using Flash in Other Camera Modes (2) Tv: Shutter Speed-Priority AE and E-TTL Autoflash By selecting the shutter speed, you can obtain various effects with flash. You can set the shutter speed from 30 sec. to the top sync speed. The camera then sets the aperture automatically to obtain a correct exposure for the background. The E-TTL autoflash system controls the flash exposure based on the camera-selected aperture.
Using Flash in Other Camera Modes (3) M: Manual Exposure and E-TTL Autoflash In this mode, you set both the shutter speed and aperture. The E-TTL autoflash system controls the flash exposure based on the the aperture you set. •i Set the camera's picture-taking mode ' to M and set the desired aperture and shutter speed anywhere from 30 sec. to the top sync speed. You can also use buLb. Q Set the 550EX’s flash mode to ^ ETTL. 0 O.S 0.7 Focus the subject.
For Type-A Cameras Advanced Flash Photography This section explains advanced flash operations possible with the Speedlite 550 EX. It contains the following: 1. High-Speed Sync (FP Flash) (page 32) 2. FE Lock (page 34) 3. Flash Exposure Compensation (page 36) 4. FEB (Flash Exposure Bracketing) (page 38) 5. Bounce Flash (page 40) 6 . Close-Distance Flash Photography (page 43) 7. Manual Flash Mode (page 44) 8 . Stroboscopic Flash (page 46) 9. Second-Curtain Synchronization (page 49) 10.
1. High-Speed Sync (FP Flash) When you set the synchronization mode to high-speed sync (FP flash), the camera can synchronize with the 550EX at all shutter speeds. When high speed sync has been set, iiH is displayed in the viewfinder. • High-speed sync can be used in the E-TTL and M Hash modes. • High-speed sync is especially effective for fill-flash portraits in daylight since you can (1) Obtain belter background blur with a larger aperture. (2) Create a catchlight in the subject's eyes.
High-Speed Sync (FP Flash) Check that the icon is displayed in the viewfinder, then take the picture. The image was removed due to copyright restrictions With normal flash. The image was removed due to copyright restrictions With high-speed sync. With high-speed sync, the Guide No. changes depending on the shutter speed (se page 121). The faster the shutter speed, the shorter the flash range will be. Check current flash range on the SSOEX's LCD panel.
2. FE Lock You can use FE (flash exposure) lock with Type-A cameras. This is the flash version of AE lock. With FE lock, you use spot metering to obtain the correct flash exposure reading for a specific part of the subject. ■ FE lock works with E-TTL and high-speed sync (FP flash). H Select a picture-taking mode with the ' camera. 2 Focus the subject. O Aim the viewfinder's spot metering circle over the part of the subject to be metered. Then press the button on the camera.
FE Lock Check the flash exposure level in the viewfinder, then take the picture. i 60 5.6 The image was removed due to copyright restrictions M For this shot, FE lock was used for the subject’s face before the picture was recomposed. FE lock prevented the wall’s bright reflection from throwing off the exposure. The subject was thus correctly exposed. If the subject Is too far away to obtain a correct flash exposure, i will blink in the viewfinder.
3. Flash Exposure Compensation Flash exposure compensation with the 550EX can be set up to ±3 stops in 1/3-stop increments (or 1/2-stop increments with some cameras). You can also use flash exposure compensation in combination with normal exposure compensation (to control the background's exposure level) in a flash picture. . . I ^ Z o o m Summ - B--------hi- “t Press * select the button and • Pressing ihe button changes the blinking setting in the following loop: •S0.7 1 1.

In such a case, use the manual flash mode.
4. FEB (Flash Exposure Bracketing) With FEB, you can obtain bracketed flash shots of the subject while the background exposure level remains the same. Three bracketed flash shots can be taken: Correct exposure, underexposure, and overexposure. The three shots can be bracketed up to ±3 stops in 1/3-stop increments (or 1/2stop increments with some cameras). After all three bracketed flash shots are taken, FEB is canceled automatically. Press the button and select %.

"7 Take the remaining two bracketed ' shots. (If necessary, repeat steps 4 to 6 .) The image was removed due to copyright restrictions Correct exposure. The image was removed due to copyright restrictions Underexposure by 1 stop.
5. Bounce Flash With direct, frontal flash, harsh shadows are usually created in the background behind the subject. This can be avoided by bouncing the flash off a nearby wall or ceiling. Bounce flash also gives softer lighting effects. •i To turn the flash head, press the ■ <(pSiH|> button. To tilt the flash head, press the <©> button. Turn and/or tilt the flash head and point it at a wall, ceiling, or other reflective surface. The flash head can be pointed in the directions and angles listed below.
Bounce Flash A Check that the i icon is displayed in ^ the viewfinder, then take the picture. • If the flash exposure confirmation lamp does not light after you take the picture, use a larger aperture (smaller f-number) and try again. The image was removed due to copyright restrictions With bounce flash. The image was removed due to copyright restrictions Without bounce flash. Bounce the flash on a plain, white, reflective surface. If a colored surface is used, the 41 picture may have a color cast.
Bounce Flash • Creating a Catchiight The image was removed due to copyright restrictions A catchiight is a reflection of the flash in the subject's eyes. A catchiight in the eyes makes the subject look more lively. For portraits, you can easily create a catchiight with the 550EX. Tilt the flash head upward all the way by 90*. Extend the built-in wide panel until it clicks in place as shown in the figure. To take a picture, follow the same procedure in "5. Bounce Flash.
6. Close-Distance Flash Photography The flash head can be tilted downward by T. This position enables the flash to better illuminate the lower part of a subject that is close to the camera. ETTL Zoom 5umm 0.5 0.7 1 1.5 2^/^ H I M Press the <©> button and tilt the flash head downward until it stops. The icon will blink on the LCD panel. * • ■ This flash head position is effective only for subjects 0.5 meter /1.6 ft to 2 meters / 6.6 ft from the camera.
7. Manual Flash Mode In the manual flash mode, you can set the flash output from 1/1 (full) to 1/128 power in full-stop increments. • To prevent overheating and deterioration o( the flash head, observe the following limits for continuous shooting with flash: (1) At 1/1 or 1/2 output: Max. 15 continuous flash shots. (2) At 1/4 or 1/8 output: Max. 20 continuous flash shots. (3) At 1/16 or 1/32 output: Max. 40 continuous flash shots. •1 Set the camera's picture-taking mode ' to Av or M.
Manual Flash Mode Press the <+> or <—> button to set the desired flash output. • Each time the button is pressed, the flash output changes by one stop. C Press the button again. The manual flash output display will stop blinking and remain displayed. 0 Focus the subject. • When you press the shutter button halfway, focus will be achieved and the aperture and flash range (bar segment) will be displayed on the LCD panel, y Check the focusing distance on the * lens. 0.5 0.7 1.
8. Stroboscopic Flash With stroboscopic flash, a rapid series of flashes is fired. It can be used to record multiple images of a moving subject in a single photograph for later study. You can set the firing frequency (the number of flashes per sec. expressed as Hz) from 1 Hz to 199 Hz. The firing frequency can be set in 1-Hz increments from 1 Hz to 20 Hz, in 5-Hz increments from 25 Hz to 50 Hz, and in 10-Hz increments from 60 Hz to 199 Hz.

When selected, the respective item blinks on the LCD panel to indicate that it can be altered.
Stroboscopic Flash p Use the following formula to calculate ^ the required shutter speed. Flash count Firing frequency = Shutter speed Example; If the flash count is 10 and the firing frequency is 5 Hz, the shutter speed will have to be at least 2 sec. 10-t5 = 2 • If the flash count display is - -. the flash will keep firing until the shutter speed ends or until the maximum number of continuous flashes (as indicated in the table on page 122) is fired. 2 Focus the subject.
9. Second-Curtain Synchronization Normally, the flash fires in synchronization with the first shutter curtain when the shutter is fully open. With second-curtain synchronization, the flash fires immediately before the second shutter curtain closes at the end of the exposure. With second-curtain synchronization and a slow shutter speed, you can create a trailing blur (illuminated by ambient light) that trails a moving subject (illuminated by the flash) to give a natural-looking illusion of motion.
10. Modeling Flash When the 550EX is used with the EOS-3, a modeiing flash can be fired so you can check the lighting and shadow effects before you take the picture. II 53 __________ --------------------- Set the desired flash photography settings with the camera and 550EX. Press the camera’s depth-of-field preview button. • The aperture will stop down. • The 550EX will fire a series of flashes at 70 Hz lor 1 sec. Custom Function CF-6 can disable the modeling flash and prevent it from firing.
For Type-A Cameras Wireless Flash Photography This section covers wireless flash photography with the 550EX. It explains the 550EX’s built-in master and slave flash features. 550EX Wireless Flash Features • A wireless flash system with multiple Speedlite 550EXs can be used as easily as a single, on-camera Speedlite 550EX. • Up to three 550EXs or three groups of 550EXs can be set as slave units for automatic control. • 550EXS set as slave units can be positioned to obtain the desired lighting effects.
[1] Wireless System Setup and Testing The wireless flash system can be setup in one of two ways: ® With a 550EX set as the master unit and one or more 550EXs set as slave units. (D With Speedlite Transmitter ST-E2 (sold separately) used as the master unit and one or more 550EXs set as slave units. This section describes the procedure for the former. For the latter, refer to the Instructions for Speedlite Transmitter ST-E2. 1.
2. Setting the 550EX as a Slave Unit Set the wireless selector to SLAVE on the 550EX to be used as a slave unit. A 550EX set in this way is called a "slave unit.” • The slave unit’s flash head zoom setting Is set automatically to Q mm. [=1 You can change the slave unit’s flash head zoom setting manually with the ZOOM L|i button.
3. Setting the Master/Slave Channel To prevent your master unit from firing another photographer’s siave units, four channels are provided to differentiate your slave units from unreiated ones. The master unit and slave unit(s) in the same wireless flash system must be set to the same channel No. ■1 To set the master unit’s channei No.
Setting the Master/Slave Channel Press the < + > or < —> button to set the same channel No. (1, 2, 3, or 4) as the master unit’s. Press the button. • The BBB icon and channel No. will be displayed. If the master unit and slave unit(s) are not set to the same channel No., the master unit will be unable to trigger the slave unit’s flash. Make sure the channel No. is the same.
4. Setting the Slave ID With multiple slave units, a slave ID can be assigned to distinguish a slave unit as being the main flash or fill flash. A flash ratio can thereby be set. Three slave IDs are available: A. B, and C. H To set a slave unit’s slave ID, press * the button and select BI^. • Pressing the button changes the selection in the loliowing loop: (Olf) Press the <+> or <-> button to set the slave ID {A, B, or C).

• Speedlite Transmitter ST-E2 (Sold separately) Speedlite Transmitter ST-E2 serves as the master unit for wireless Speedlite 550EX control. It can control up to two slave unit groups (A and B). It is attached directly to the camera's hot shoe. As a master unit, the differences between the 550EX and Speedlite Transmitter ST-E2 are listed below.
For Type-В Cameras Basic Flash Photography When the Speedlite 550EX is attached to a Type-B camera such as the EOS1 N, you can take flash pictures with TTL autoflash as easily as normal aufoexposure (AE) pictures. Flash photography can be fully automatic—all you do is press the shutter button. Or you can set the desired shutter speed and aperture and still obtain autoflash exposure.
1. Using Flash in Full Auto Mode Set the camera’s picture-taking mode to P (Program AE) or □ (Full Auto). Flash photography will then be as easy as normal AE photography. The camera sets the aperture and shutter speed automatically to suit a wide variety of lighting conditions including outdoor fill flash. The E-TTL autoflash system sets the flash exposure automatically. H Set the camera's picture-taking mode ' toP. TTL 0.5 0.7 1 Zoom 5umm 1.5 2 3 4 $ 1.5 2 3 4 6 9 13 16 m 9 13 16 m ■ O.S 0.
Using Flash in Full Auto Mode After the flash fires, check that the flash exposure confirmation lamp lights. When a correct flash exposure has been obtained, the flash exposure confirmation lamp lights for about 3 sec. If the lamp does not light, the flash may have been insufficient, resulting in underexposure. In such a case, check that the pilot lamp is red, then move closer to the subject and take the picture again. Fill Flash Fill flash can be used outdoors in daylight to supplement existing light.
2. Using Flash in Other Camera Modes Flash photography is also automatic in the other picture-taking modes. In the Av (aperture-priority AE), Tv (shutter speed-priority AE), and M modes, the TTL autoflash system sets the flash exposure automatically. The camera sets the necessary shutter speed (in the Av mode), aperture (in the Tv mode), or flash output (in the M mode). Flash photography is as easy as normal AE picture-taking.
Using Flash in Other Camera Modes (1) Av: Aperture-Priority AE and TTL Autoflash This mode is effective for controlling the depth of field in your flash pictures. You can also obtain a balanced exposure between the subject and background. You set the aperture and the camera sets the shutter speed automatically to obtain a correct exposure for the background. The TTL autoflash system obtains the proper exposure based on the aperture you set. 1 toSetAv.
Using Flash in Other Camera Modes • Balanced Flash Exposures In low-light situations, the exposure level can be balanced between the subject and background by using a slow sync speed. You can obtain balanced flash exposures automatically by setting the camera's picture-taking mode to Av. The camera then sets the sync speed automatically to suit the background. Using a tripod is recommended to prevent camera shake. The image was removed due to copyright restrictions Balanced flash exposure.
Using Flash in Other Camera Modes (2) Tv: Shutter Speed-Priority AE and TTL Autofiash By selecting the shutter speed, you can obtain various effects with flash. You can set the shutter speed from 30 sec. to the top sync speed. The camera then sets the aperture automatically to obtain a correct exposure for the background. The TTL autoflash system controls the flash exposure based on the camera-selected aperture.
Using Flash in Other Camera Modes (3) M: Manual Exposure and TTL Autoflash In this mode, you set both the shutter speed and aperture. The TTL autoflash system controls the flash exposure based on the aperture you set. camera's picture-taking mode 1 toSetMtheand set the desired aperture and shutter speed anywhere from 30 sec. to the top sync speed. You can also use buLb. the 2 Set TTL. 550EX's flash mode to 3 Focus the subject.

2. FEB (Flash Exposure Bracketing) With FEB, you can obtain bracketed flash shots of the subject while the background exposure level remains the same. Three bracketed flash shots can be taken; Correct exposure, underexposure, and overexposure. The three shots can be bracketed up to ±3 stops in 1/3-stop increments (or 1/2stop increments with some cameras). After all three bracketed flash shots are taken, FEB is canceled automatically.

The image was renx>ved due to copyright restrictions Correct exposure.
3. Bounce Flash With direct, frontal flash, harsh shadows are usually created in the background behind the subject. This can be avoided by bouncing the flash off a nearby wall or ceiling. Bounce flash also gives softer lighting effects. To turn the flash head, press the <(5E)> button. To tilt the flash head, press the <©> button. Turn and/or tilt the flash head and point it at a wall, ceiling, or other reflective surface. The flash head can be pointed in the directions and angles listed below.
Bounce Flash Check that the i icon is displayed in the viewfinder, then take the picture. • If the flash exposure confirmation lamp does not light after you take the picture, use a larger aperture (smaller f-number) and try again. Bounce the flash on a plain, white, reflective surface. If a colored surface is used, the picture may have a color cast. The image was removed due to copyright restrictions With bounce flash. The image was removed due to copyright restrictions Without bounce flash.
4. Close-Distance Flash Photography The flash head can be tilted downward by 7°. This position enables the flash to better illuminate the lower part of a subject that is close to the camera.

The manual flash output display will stop blinking and remain displayed. e Focus the subject. ^ • When you press the shutter button halfway, focus will be achieved and the aperture and flash range (bar segment) will be displayed on the LCD panel.
6. Stroboscopic Flash With stroboscopic flash, a rapid series of flashes is fired. It can be used to record multiple images of a moving subject in a single photograph for later study. You can set the firing frequency (the number of flashes per sec. expressed as Hz) from 1 Hz to 199 Hz. The firing frequency can be set in 1 -Hz increments from 1 Hz to 20 Hz, in 5-Hz increments from 25 Hz to 50 Hz, and in 10-Hz increments from 60 Hz to 199 Hz.
Stroboscopic Flash p Press the button to ^ select the firing frequency, flash count, or flash output display. When selected, the respective item blinks on the LCD panel to indicate that it can be altered. Pressing the button changes the blinking item in the following loop: □ Firing frequency-► Fiash counl-^Fiash output -------------------(Normal display)-^------ „M Zoom Sumn; j ^ ulti ^ ^ i/iea / i VI Press the <+> or <-> button to set the desired value for the blinking item.
Stroboscopic Flash p Use the following formula to calculate ^ the required shutter speed. Flash count Firing frequency = Shutter speed Example: If the flash count is 10 and the firing frequency is 5 Hz, the shutter speed will have to be at least 2 sec. 10-5 = 2 • If the flash count display is - -, the flash will keep firing until the shutter speed ends or until the maximum number of continuous flashes (as indicated in the table on page 122) is fired. 0 Focus the subject.
7. Second-Curtain Synchronization Normally, the flash fires In synchronization with the first shutter curtain when the shutter is fully open. With second-curtain synchronization, the flash fires immediately before the second shutter curtain closes at the end of the exposure. With second-curtain synchronization and a slow shutter speed, you can create a trailing blur (illuminated by ambient light) that trails a moving subject (illuminated by the flash) to give a natural-looking illusion of motion.
For Type-B Cameras Wireless Flash Photography This section covers wireless flash photography with the 550EX. It explains the 550EX’s built-in master and slave flash features. A wireless flash system with multiple Speedlite 550EXs can be used as easily as a single, on-camera Speedlite 550EX.
