Cautions for firing continuous flashes
- To avoid degrading and damaging the flash unit due to overheating, do not fire more than 20 continuous flashes. After 20 continuous flashes, allow a rest time of at least 10 min.
If you fire 20 continuous flashes, and then fire the flash again repeatedly in short intervals, the safety function may activate and restrict flash firing. While flash firing is restricted, the firing interval is automatically set to a time between approx. 8 and 15 sec. If this happens, allow a rest time of at least 10 min.
For details, see “Flash Firing Restriction due to Temperature Increase” on page 69.

Getting Started with Macro Flash Shooting
This chapter describes the preparations before starting macro flash shooting and the basic shooting operations.

Conditions of the subject greatly influence the exposure when shooting close-ups. Therefore, it is recommended to shoot the same subject with different exposures (p.27) and check the exposure immediately after shooting.
When the camera's shooting mode is set to a fully automatic mode or an Image Zone mode, the functions with ☆ added to the right side of the page title cannot be set. Set the camera's shooting mode to P/Tv/Av/M/B (Creative Zone mode) to enable all the operations in this chapter.
Installing the Batteries
Use four AA/R6 batteries.

1 Open the cover.
- Slide the lock-release lever to the left as shown in the illustration, slide the cover down, then open the battery compartment cover.

Install the batteries.
- Make sure the “+” and “-” battery contacts are correctly oriented as shown in the battery compartment. - The grooves on the side surfaces of the battery compartment indicate “-”. This is convenient when replacing the batteries in a dark place.

2 Close the cover.
- Close the battery compartment cover and slide it up. - When it clicks in place, the battery compartment cover is locked.
Firing Interval and Number of Flashes
| Firing Interval | Number of Flashes | |
| Quick Flash Normal Flash | ||
| Approx. 0.1 to 3.3 sec. | Approx. 0.1 to 5.5 sec. | Approx. 100 to 700 |
- Based on new AA/LR6 alkaline batteries, both sides firing, and Canon's testing standards.
- The Quick flash function enables flash shooting before the flash is fully charged (p.18).

Note that certain AA/R6 lithium batteries may become extremely hot in rare cases during usage. Due to safety reasons, do not use “AA/R6 lithium batteries”.
- Using AA/R6 batteries other than the alkaline type may cause improper battery contact due to the irregular shape of the battery contacts.

- Be aware that the batteries may become hot, if you change batteries after firing flashes continuously.
- Batteries are required by the flash unit even when an external power source (p.68) is used.

- When <∞> is displayed, or the LCD panel display turns off during recycling, replace the batteries with new ones.
Use a new set of four batteries of the same brand. When replacing the batteries, replace all four at one time.
AA/HR6 Ni-MH batteries can also be used.
Attaching the Control Unit to the Camera

1 Attach the control unit.
- Slip the control unit's mounting foot all the way into the camera's hot shoe.

Secure the control unit.
- Slide the mounting foot lock lever to the right.
When the lock lever clicks in place, it is locked.

3 Detach the control unit.
While pressing the lock-release button, slide the lock lever to the left and detach the control unit.

Be sure to turn off the MR-14EX II before attaching or detaching it.
Attaching the Flash Unit to the Lens
Attach the flash unit to the front of the macro lens.

Attach the flash unit to the front of the lens while holding down the release button.
Make sure that the flash unit is securely attached.
- When rotating the flash unit, lightly press the release button while rotating it.
- Detach the flash unit while holding down the release button.
Attaching the Lens Cap
Attach the provided lens cap to the flash unit when it is not used in order to protect the lens.

A 67 mm diameter filter can also be attached to the flash unit (p.17).

- Be sure to attach the flash unit to the lens when shooting. Shooting while holding the flash unit in your hand may result in a low temperature burn.
- Do not touch the flash unit or batteries immediately after continuous flash firing or modeling flash (p.23). Touching them may result in a burn. Make sure that the flash unit has cooled before detaching the flash unit or replacing batteries.

When using the following lenses, attach the Macrolite Adapter (sold separately) to the front of the lens (filter thread) and then attach the flash unit.
• EF100mm f/2.8L Macro IS USM: Macrolite Adapter 67
• EF180mm f/3.5L Macro USM: Macrolite Adapter 72C
Using a Filter

A commercially-available filter can be used during flash shooting. A filter can be attached, using the two procedures described below. Filters may not be used together with some macro lenses.
(1) Attach a 67 mm filter on the front face of the flash unit (see the above illustration).
(2) Attach the flash unit to the lens with the filter attached to the front of the lens (filter thread).
| Macro Lens | Filter Compatibility | |
| (1) (2) | ||
| EF50mm f/2.5 Compact Macro Not usable* | 1 | Usable |
| EF100mm f/2.8 Macro | Usable | |
| EF100mm f/2.8 Macro USM Not usable | ||
| EF100mm f/2.8L Macro IS USM | Conditionally usable*2 | |
| EF180mm f/3.5L Macro USM | ||
| EF-S60mm f/2.8 Macro USM Usable | ||
| MP-E65mm f/2.8 1-5x Macro Photo Not usable | ||
*1: The lens cannot be used with a filter, since focusing is interrupted by an attached filter touching the front of the lens. Also, filter may be damaged or the lens malfunction may result.
*2: Attach a filter to the front of the lens before attaching Macrolite Adapter (p.16) to the front part of the filter. If attachment threads are not provided on the front rim of the filter, the flash unit cannot be attached since Macrolite Adapter cannot be attached. Note that if the flash unit is attached after a filter and Macrolite Adapter are attached to the front of the lens, the periphery of the photo may look darker.
Using a Hood
If you want to use a dedicated hood with the MP-E65mm f/2.8 1-5x Macro Photo (sold separately), attach the flash unit after attaching the hood to the lens.
A hood cannot be attached when using any other macro lens.

Using E-TTL II and E-TTL Autoflash by Shooting Mode
Simply set the camera's shooting mode to
| Av | You can perform flash shooting while obtaining a standard exposure of both the main subject and background while considering the depth of field.Select this mode when you want to set the aperture manually. The camera will then automatically set the shutter speed, matching the aperture to obtain a standard exposure. If the scene is dark, a slow sync speed will be used to obtain a standard exposure for 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 long exposure using 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. |
| M | Select this mode if 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 and aperture combination you set. |
