MANUAL DE INSTRUCCIONES
English
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.

Conventions Used in this Manual
This manual covers both the MR-14EX and MT-24EX. The instructions basically apply to the MR-14EX. If you have the MT-24EX, read the parts.
The operation procedures in this instruction manual assume that both the camera and MR-14EX/MT-24EX’s power switches are ON.
Icons are used in the text to indicate the respective buttons, dials, and settings. They match the same icons found on the camera and MR-14EX/MT-24EX.
The (1) / (3) icons indicate that the respective function remains in effect for 8 sec. or 16 sec.
Reference page numbers are indicated by (p.**).
This instruction manual uses the following alert symbols:
: The Caution symbol indicates a warning to prevent shooting problems.
: The Note symbol gives supplemental information.

Based on a new set of batteries and Canon’s testing standards.
The figures are the same for both flash tubes/heads firing or single tube/head firing.
This applies to both the MR-14EX and MT-24EX.
Use a new set of four batteries of the same brand. When replacing the batteries, replace all four at one time.
Using size-AA batteries other than the alkaline type (LR6) may cause improper battery contact due to the irregular shape of the battery contacts.
Size-AA Ni-MH (HR6) or lithium (FR6) batteries can also be used.

Setting the Flash Unit
Adjustable Range of Flash Unit
The MT-24EX’s flash unit can be adjusted within the range shown below to match the lens and subject.
Standard position index (Horizontal angle) Angle setting scale
Standard position index (Vertical angle)
1This can be rotated. Be sure to hold down the release button when rotating the mount ring. After rotating it to the desired position, release the release button.
2Hold down the rotate button and turn the flash head mount. The flash head can be moved directly at 3 and 4.
Do not adjust the flash head angle beyond the adjustable range. Doing so may cause the flash head to detach and fall from the flash head mount.
The adjustable range may be further limited depending on the camera and lens.

Flash Setting Guide
This is a general guide to setting the flash angle for various magnifications with a macro lens. Refer to the angle scale (15° increments) on the side of the flash head and set the same angle for both flash heads A and B. The angle specifications in the table below indicate the inner angle relative to the flash head’s standard position index (horizontal).

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.

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.
20
mnSetting 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 |
Only flash tube/head A Only flash tube/head B |

2
Select <yl>.
Press the <f> button to display <yl>.
Set the flash ratio.
Press <b> 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.
Since the exposure will be controlled automatically, there is no need to calculate the exposure.
If the flash mode is <q>, see page 27.
21
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.
22
7FE 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 <P> button.
1
2
Focus the subject.
Press the <7> button. (3) Place the subject at the center of the viewfinder and press the <7> button.
XThe MR-14EX/MT-24EX will fire a preflash and the required flash output for the subject is retained in memory.
XThe FEL display will be shown in the viewfinder for 0.5 sec.
Each time you press the <7> button, a preflash is fired to update the FE lock reading.
If the subject is too far away and underexposure will result, the <Q> icon will blink in the viewfinder. Move closer to the subject and try the FE lock again.
If <a> is not displayed on the LCD panel, FE lock cannot be set. If the subject is too small, FE lock might not be very effective.
23
fFlash Exposure Compensation
In the same way as normal exposure compensation, you can set exposure compensation for flash. The flash exposure compensation amount can be set up to ±3 stops in 1/3-stop increments.
1 Select <f>.
Press the <a> button to display <f>.
X <f> and the flash exposure compensation amount will blink.

amount will be set.
If the flash exposure compensation amount has been set by both the MR-14EX/MT-24EX and camera, the MR-14EX/MT-24EX’s flash exposure compensation amount will override the camera’s.
If the camera’s exposure setting increment is 1/2 stop, the flash exposure compensation will be set in 1/2-stop increments.
24
gFEB
The camera brackets the flash exposure automatically up to ±3 stops in 1/3-stop increments for three successive shots. This is called FEB (Flash Exposure Bracketing).
1 Select <g>.
Press the <a> button to display <g>.
X <g> and the bracketing amount will blink.
2Set the flash exposure bracketing amount.
Press the <h> or <i> button to set the bracketing amount.

cHigh-speed sync
With high-speed sync (FP flash), the flash can synchronize with all shutter speeds.
Select <c>.
Press the <h> and <i> buttons simultaneously to display <c>.
In the viewfinder, check that the <F> icon is lit.
If the shutter speed is slower than the maximum flash sync speed, <F> will not be displayed in the viewfinder.
To return to normal flash, press the <h> and <i> buttons simultaneously to turn off <c>.
With high-speed sync, the faster the shutter speed, the shorter the flash range will become.
rSecond-curtain sync
With a slow shutter speed, you can create a light trail following the subject. The flash fires right before the shutter closes.
Select <r>.
Press the <h> and <i> buttons simultaneously to display <r>.
The camera’s “buLb” mode works well with second-curtain sync. To return to normal flash, press the <h> and <i> buttons simultaneously to turn off <r>.
With E-TTL II/E-TTL, two flashes will be fired even at slow shutter speeds. The first flash is the preflash.
