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.
Reference ................35 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-24, 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.

Size-AA alkaline batteries Approx. 0.1 - 7 sec. Approx. 120 - 800 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.
Attaching the Control Unit Loosen the locking ring. Turn the locking ring as shown by the arrow to loosen it. Attach the control unit. Slip the control unit’s mounting foot into the camera’s hot shoe all the way. Tighten the locking ring. Turn the locking ring as shown by the arrow.
Attaching the Flash Unit MR-14EX Hold down the release buttons and attach the flash unit to the front of the lens. Make sure the flash unit is securely attached. The flash unit can be rotated. To detach the flash unit, follow the above procedure in reverse.
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) 1 This can be rotated.
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).

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 MR- 14EX/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.
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.
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...
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.
Aim the subject at the center of the viewfinder and press the <7> button. The MR-14EX/MT-24EX will fire a preflash and the required flash output for the subject is retained in memory. The FEL display will be shown in the viewfinder for 0.5 sec.
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...
After the three shots are taken, FEB will be cancelled automatically. FEB can be used together with FE lock or flash exposure compensation set with the MR-14EX/MT-24EX. If the camera’s exposure setting increment is 1/2 stop, the FEB will be...
c High-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.
q Manual Exposure You can set the flash output manually from full output at 1/1 to 1/64 output in full-stop increments. The flash can be fired in one of three ways: 1. A and B fired at the same output, 2. A and B fired at a different output, 3. Only A or B is fired. You should first take a test shot to check the exposure.
C Setting Custom Functions Custom Functions enable you to customize MR-14EX/MT-24EX features to suit your picture-taking preferences. Display the <l> icon. Hold down the <A> button for 2 sec. or more. Select the Custom Function No. Press the <a> button, and the Custom Function number and setting number will blink.

C.Fn-7:If an external power source is used, the flash recycling is powered concurrently by the internal batteries and external power source. In this case, when the internal batteries become exhausted, shooting might not be possible. If 1 is set, the flash recycling will be powered only by the external power source.
Wireless Multiple Flash Photography With one or more EX-series Speedlites having a slave function, you can create a wireless, multi-Speedlite flash system. It is as easy to use as normal E-TTL II autoflash.

C. Slave C can be used to eliminate shadows or create an accent light. The flash exposure is controlled automatically to obtain a standard exposure with both flash tubes/heads A and B, as well as with slave C by itself. MR-14EX Slave C Indoors Outdoors 3m (9.8ft.)

Set the MR-14EX or MT-24EX as the master unit. Press the <D> button to select <a>. Press the <f> button to select <yk>. <w> will be displayed. Press the <e> button to select a channel 1 to 4. Set the slave unit.
Page 34
Check that the wireless flash system works. Press the master unit’s test firing button. The master unit and slave unit(s) C will fire. If the slave unit(s) does not fire, adjust the position, angle, and distance from the master unit. The wireless multiple flash system requires both flash tubes/heads A and B to fire.
