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.

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.

To prevent the flash tube/head from deteriorating due to
excessive heat, do not fire the flash continuously more than 20
times. After firing the flash continuously for 20 times, let the MR-
14EX/MT-24EX rest for 10 min. or longer. During continuous
manual flash firing, allow the MR-14EX/MT-24EX to rest after the
firing times indicated below.

Recycling Time and Flash Count
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.
Installing the Batteries
Battery Type Recycling Time Flash Count
Size-AA/LR6 alkaline batteries Approx. 0.1 - 7 sec. Approx. 120 - 800
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 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).
