Thank you for purchasing a Canon product.

The Canon Macro Ring Lite MR-14EX and Macro Twin Lite MT-24EX are macro flash units compatible with E-TTL II/E-TTL/TTL autoflash systems.

Read this instruction manual while also referring to your

camera’s instruction manual.

Before using the MR-14EX/MT-24EX, read this instruction manual and your camera’s instruction manual to familiarize yourself with macro flash operations.

The basic operation is as easy as with normal AE shooting.

When the MR-14EX or MT-24EX is attached to an EOS camera, almost all automatic exposure control for flash photography is handled by the camera.

Although the MR-14EX/MT-24EX is an external flash unit, it works automatically and seamlessly like the camera’s built-in flash.

It is automatically compatible with the camera’s flash metering

mode (E-TTL ll, E-TTL, or TTL).

The camera controls the MR-14EX/MT-24EX automatically in the following flash metering modes:

1. E-TTL II autoflash (evaluative flash metering with preflash reading/lens distance information)

2. E-TTL autoflash (evaluative flash metering with preflash reading)

3. TTL autoflash (off-the-film metering for real-time flash metering)

Regarding the camera’s available flash metering modes, refer to the “External Speedlite” specification in the “Specifications” of your camera’s instruction manual.

The camera instruction manual’s chapter on flash photography will refer to cameras having 1 and 2 above as a Type-A camera (compatible with E-TTL II or E-TTL). And cameras having 3 (compatible with only with TTL) are called Type-B cameras.

* This instruction manual assume that you are using the MR-14EX/MT-

24EX with a Type-A camera.

For Type-B cameras, see page 41.

Setting the correct exposure for closeup shots largely depends on the subject. It is best to bracket the exposure for the same subject. (p.24)

If the EOS camera has a initialize function for camera settings, initializing the camera settings will also initialize the flash settings (excluding Custom Function settings).

Turning on the Power Switch

Turn on the power switch.

Set the power switch to <K> or

<g>.

X The flash recycling starts.

Check that the flash is ready.

The pilot lamp will light in red (fully

charged) when the flash is ready.

X Pressing the pilot lamp will fire a test

flash.

To save battery power, the <g> Save Energy feature automatically turns off the MR-14EX/MT-24EX after 90 sec. of non-operation. To turn on the MR14EX/MT-24EX again, press the camera’s shutter button halfway.

A test firing cannot be fired while the camera’s operation timer 4 or 0

is active.

The MR-14EX/MT-24EX’s settings will be retained in memory even after

the power is turned off. To retain the MR-14EX/MT-24EX’s settings when you replace the batteries, replace the batteries within 1 minute after turning off the power.

Fully Automatic Flash Shooting

When the camera’s shooting mode is set to <V> (Program AE) or (Full

uto), E-TTL II/E-TTL fully automatic flash photography will be enabled, making

it as easy as normal AE shooting in the <V> or mode.

Set the MR-14EX/MT-24EX to <

Press the <D> button to

display <a>.

Take the picture.

Focus the picture and check that the

<Q> icon is lit in the viewfinder.

If a standard flash exposure was obtained, the flash exposure confirmation lamp will light for about 3 sec.

ETTL>.

Automatic Flash in Each Shooting Mode

Just set the camera’s shooting mode to <W> (aperture-priority AE) or <O> (manual exposure) to enable macro flash shooting with E-TTL II/ E-TTL autoflash.

<W> Aperture-priority AE

This mode is effective for controlling the depth of field or obtaining the standard exposure for both the subject and background. You set the aperture as desired, and the shutter speed is set automatically (30 sec.

- 1/X* sec.) to obtain the standard background exposure. Based on the set aperture, E-TTL II/E-TTL autoflash is used for the shot.

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.

<O> Manual exposure

Select this mode when you want to set both the shutter speed and aperture manually. Standard exposure of the main subject is obtained with the flash. The exposure of the background is obtained with the shutter speed (buLb, 30 sec. - 1/X* sec.) and aperture combination you set.

With <X> (shutter-priority AE), you set the shutter speed (30 sec. - 1/X*

sec.) as desired, and the camera sets the aperture automatically. However, this mode is not recommended since you cannot set the aperture.

In the <Z> or <Y> mode, the result will be the same as shooting in the

<V> mode.

* 1/X sec. is the respective camera’s maximum flash sync speed.

: Flash range

The MT-24EX’s flash range largely depends on the flash head’s position.

When shooting at the closest focusing distance, stop down the aperture by 3 stops (ISO 100) from the maximum aperture.

mn Setting the Flash Ratio

You can adjust the flash ratio of flash tubes/heads A and B or fire only one of the flash tubes/heads. This can create shadows on the subject to give a more sculptural look. The flash ratio can be set in half-stop increments as follows: 1:8 - 1:1 - 8:1 (13 settings)

A:B = 1:1 A:B = 4:1

Since the exposure will be controlled automatically, there is no need to

calculate the exposure.

If the flash mode is <q>, see page 27.

Only flash tube/head A Only flash tube/head B

Select <yl>.

Press the <f> button to display

<yl>.

Set the flash ratio.

Press or <c> to select from

1:8 - 1:1 - 8:1. The extreme left or right setting will fire only one of the flash tubes/heads.

X <m>: Only <j> will be fired.

<n>: Only <k> will be fired.

The value of the bar in the flash ratio scale below is indicated in

parentheses.

(5.6:1) (2.8:1)(1.4:1) (1:1.4) (1:2.8) (1:5.6)

In terms of aperture stops, the flash ratio range is equivalent to 3:1 - 1:1 -

1:3.

If the picture is taken while <y> is not displayed, flash tubes/heads

A and B will fire at the same output.

Flash ratio control is not possible with the following cameras. You can fire

both flash tubes/heads at the same output or fire only one of the flash tubes/heads. EOS ELAN ll/ELAN ll E/50/50E, EOS REBEL G/500N, EOS IX, EOS IX Lite/IX7, EOS 3000/88, EOS REBEL 2000/300, EOS REBEL XS N/ REBEL G II/3000N/66

Modeling Flash

If the camera has a depth-of-field preview button, pressing it will fire the flash continuously for 1 sec. This is called the modeling flash. It enables you to see the shadow effects on the subject and the lighting balance. The modeling flash also works with a wireless, multi-Speedlite system.

7 FE Lock

FE (flash exposure) lock locks the correct flash exposure reading for any part of the scene. With <a> displayed on the LCD panel, press the camera’s <7> button. If the camera does not have a <7> button, press the button.
