Installing the Batteries

Slide the battery compartment cover

and open it as shown by the arrows.

Install two batteries.

 Make sure the + and - battery contacts are correctly

oriented.

 Return the cover to its original position.

Recycling Time and Flash Count

Recycling Time: Approx. 0.1 - 5.5 sec. Flash Count: Approx. 100 flashes or more

 Based on new size-AAA/LR03 alkaline batteries and Canon’s testing standards.

COPY

 Be sure to use a new set of two batteries of the same brand. When replacing the

batteries, replace both batteries at once.

 Do not fire more than 20 continuous flashes in a short time.  If you change the batteries after firing flashes continuously, be aware that the batteries

might be hot.

 Using size-AAA/LR03 batteries other than the alkaline type may cause improper battery

contact due to the irregular shape of the battery contacts.

COPY

Attaching the Flash

Be sure to turn off the Speedlite before attaching or detaching it.

Slide the lock lever to the left and

attach the Speedlite to the camera.

 Slip the Speedlite’s mounting foot firmly all the way

into the camera’s hot shoe.

Secure the Speedlite.

 Slide the lock lever to the right.  To remove the Speedlite, slide the lock lever to the

left and detach it from the camera.

Flash Shooting

1 Press and hold the power button for at

least 1 second to turn on the flash.

BThe power lamp turns on and flash recycling starts.

2 Check that the <Q> lamp is lit.

 When the <Q> lamp lights, you can shoot with the

flash.

 See p.32 for guidelines about the flash shooting

range.

Flash Shooting in Each Camera Mode

V: Program AE

In this mode, the camera will automatically adjust the flash output level to achieve standard exposure with Program AE, which automatically sets the shutter speed and aperture according to the brightness of the subject.

• If the resulting picture is underexposed, increase the ISO speed.

X: Shutter Priority AE

In this mode, the camera will automatically adjust the flash output level to achieve standard exposure for the automatically set aperture.

• If the aperture display blinks, it means that the background exposure will be underexposed or overexposed. Adjust the shutter speed until the aperture display stops blinking.

COPY

W: Aperture Priority AE

In this mode, the camera will automatically adjust the flash output level to achieve standard exposure for the set aperture. If the background is dark, like a night scene, a slow sync speed will be used to obtain a standard exposure of both the main subject and background. Standard exposure of the main subject is obtained with the flash, while a standard exposure of the background is obtained with a slow shutter speed.

• Since a slow shutter speed will be used for low-light scenes, using a tripod is recommended.

• If the shutter speed display blinks, it means that the background exposure will be underexposed or overexposed. Adjust the aperture until the shutter speed display stops blinking.

q: Manual Exposure

Select this mode if you want to set both the shutter speed and aperture manually. As the camera will automatically adjust the flash output level according to the aperture you set, the exposure of the main subject will be standard. The exposure of the background is obtained with the shutter speed and aperture combination you set.

Other Functions

Auto Power Off

To save battery power, power will be turned off automatically after 5 min. of idle use. To turn on the power again, press and hold the Speedlite’s power button for at least 1 second. * Canceling the auto power off function is possible. (p.14)

AF-Assist Beam

When you press the camera’s shutter button halfway, the flash may fire repeatedly. This is the AF-assist beam function that facilitates autofocus for dark scenes. Its effective range is approximately 2.8 m/9.2 ft. This function is available when using the Speedlite with an EOS DIGITAL camera that has an external flash control function. Depending on the camera model, note that the firmware may need to be updated. During wireless flash shooting, the 90EX will not fire as AF-assist beam.

COPY

Setting the Flash Functions by Camera Operation

When the 90EX is attached to an EOS DIGITAL camera with an external flash control function, the following settings are available through camera menu operations. See the camera’s instruction manual for the setting method and functions.

About Wireless Flash

 During wireless flash shooting, the 90EX fires to control the slave flash but does not fire

as a flash.

 During wireless flash shooting, the 90EX will not fire as AF-assist beam.

With multiple Canon Speedlites having the wireless flash feature, you can create various lighting effects with the same ease as using normal E-TTL II/E-TTL autoflash. The settings you input with the 90EX attached to the camera are also automatically transmitted to the slave units which are controlled by the master unit via wireless. Therefore, you need not operate the slave unit(s) at all during the shoot. The basic wireless set-up is illustrated on the next page. All you need to do is set the master unit to <a> to enable wireless E-TTL II autoflash (p.18).

Wireless Settings

You can use the menu to switch between normal flash shooting and wireless flash shooting. During normal flash shooting, be sure to turn off the wireless setting to use the flash.

Fully Automatic Wireless Flash

In this shooting mode, all flash units except the 90EX fire with the same flash output, and ETTL II autoflash is used to obtain a standard exposure from the total flash output.

Check the communication channel.

interference with other wireless multiple Speedlite systems being used. Set the same channel for both the master unit and slave unit.

Using Fully Automatic Wireless Flash

With FE lock, if even one Speedlite results in underexposure, the <Q> icon will blink. Increase the ISO speed, open the aperture, or move the slave unit closer to the subject.

Flash exposure compensation and other settings set with the master unit will also be automatically set in the slave units. Thus, you need not operate the slave unit(s). Wireless flash with the following settings can be done in the same way as with normal flash shooting.

Flash Ratio with E-TTL II

You can use two slave units together and perform E-TTL II autoflash shooting while changing the flash ratio. This is described using two slave units.

Setting the Slave Units

Set the firing groups so as to divide the two slave units into different groups. Set one unit to <1> and the other to <2>.

Wireless Flash with Three Slave Groups

 If <l> is set, the slave unit in slave group <3> will not fire.  If you point the slave unit in slave group <3> toward the subject, the subject will be

overexposed.

You can have slave groups A and B and also add slave group C. You can use slave groups A and B to obtain the standard flash exposure of the subject, and slave group C to illuminate the background to eliminate shadows.

Set the slave units.

 See “Setting the Slave Units” on page 23 to set the

slave unit’s ID to <1>, <2>, or <3>.

 For slave <3>, also set the flash exposure

compensation as necessary.

Set the master unit and shoot.

About Slave Group Control

ID = A ID = AID = A

Firing group A

COPY

If you need more flash output or want to perform advanced lighting, you can increase the number of slave units. Set an additional slave unit to the firing group (A, B or C) whose flash output you want to increase. There is no restriction on the number of units. For example, if you set a firing group with three slave units to <1>, the three units are controlled as a single firing group A with a large flash output.

Wireless Multiple Speedlite Shooting with Manual Flash Output

With manual flash and multiple Speedlites, you can set a different flash output for each slave unit. All settings are made using the menus on the camera with the master unit.

Troubleshooting Guide

If a problem occurs, refer to this Troubleshooting Guide.

The Speedlite does not fire.

• Make sure the batteries are installed in the correct orientation. (p.5)

• If the <Q> lamp does not light after 30 seconds, replace the batteries with new ones. (p.5)

• Clean the electrical contacts of the Speedlite and the camera.

The bottom of the picture looks dark.

• You were too close to the subject. Keep at least 1 m/3.3 ft. away from the subject.

• If a lens hood is attached, remove the lens hood.

• When using Mount Adapter EF-EOS M, the light from the flash may be obstructed, making the bottom of the picture dark.

The picture is really blurred.

• When the shooting mode is set to <W> mode for a dark scene, a slow sync speed is automatically set, and the shutter speed also becomes slower. Use a tripod or set the shooting mode to <
