• See page 51 for photographic examples. - If an arm is used when taking extreme close-ups with a 50mm F2.8 Macro lens, the subject may not receive sufficient lighting (p. 53).
Auto power ON/OFF
Press the flash ON/OFF button on the back of the macro flash controller.
Power of the macro flash controller comes on.


When the power of the macro flash controller is turned on, the flash-ON lamp on the control panel comes on.

If you press the flash ON/OFF button while the macro flash controller is turned on, the macro flash controller switches off and the flash-OFF lamp on the control panel comes on.
- The flash-OFF lamp goes out after about 10 seconds.
Auto power off
If the camera or macro flash controller is not used for four minutes, the power switches off and control panel indicators disappear automatically to save the batteries.
- You can disable auto power off or change the auto power off time by changing the customized settings (p. 48).
Basic flash modes (A mode/M mode)
Camera's exposure mode should be set to either A (aperture priority) mode ^1 , or M (manual) mode ^2 .
- In general close-up photography, the depth-of-field ^*3 must be quite shallow, which usually requires a smaller aperture when shooting. It is therefore better to select A or M mode, which enable you to select the aperture.
Using a macro lens is also recommended.
In this section, the basic flash operation in A or M mode with TTL metering (TTL lamp on) is described.
The following instructions from the next page assume that you are using one of the following cameras and macro lenses.
Camera: A camera with A (aperture priority) mode or M (manual) mode.
Lens: 50mm F2.8 Macro
100mm F2.8 Macro
If you photograph in P mode, refer to page 30. If using a different lens, see the aperture range graph on page 54.
^1 A mode: In A mode, you select the aperture and the camera automatically sets the shutter speed required for proper exposure.
^2 M mode: You can select both aperture and shutter speed. You can select a shutter speed that is slower than the camera's sync speed.
*3 Depth-of-field: The range behind and in front of the subject that is sharply focused. In close-up photography, this range is shallower and the out-of-focus range is wider.
1 Set the POWER switch of the camera to ON and select A or M mode.
2 Press the flash ON/OFF button to turn on the flash-ON lamp on the control panel.

3 Focus your subject and check the magnification ratio.
You can check the magnification ratio with the magnification ratio scale on the lens. (The location of the magnification ratio scale differs depending on the lens.)

4 When using M mode, select a shutter speed.
You cannot select the shutter speed faster than the camera's sync speed.
5 Select the aperture.
To find the correct aperture number, refer to pages 26 to 29.
Continuedonthenextpage
6 Select the flash.
Press the A-B button on the back of the macro flash controller to turn on the twin flash A lamp, twin flash B lamp or both twin flash lamps. (The lit lamps indicate which flash will go off.)

As viewed from the rear (control panel side), the A flash is connected to the left side socket and the B flash to the right side socket.
- For the effect of selecting the flash, see from page 51 to 53.

7 When the macro flash controller is charged, press the shutter button to take a photo.
The macro flash controller is charged when the flash-ready lamp on the control panel of the macro flash controller and the indicator in the camera viewfinder are both on.

When the correct exposure has been obtained for the photo just taken, the flash-ready lamp ↓ on the control panel blinks.

- The photo will be under-exposed if taken before charging is complete.
- The use of a tripod or remote cord is recommended to reduce camera shake.
- A camera-to-subject distance of less than 0.5m, and a magnification ratio of more than 0.15X (greater than 1:7), are recommended to get the best results from the macro flash units.
- Always turn off the macro flash controller if the twin flash unit is not connected. If the twin flash unit is not attached, but the controller is on, the camera flash sync will be in effect and the resulting ambient exposures will be incorrect.
- The camera's AF illuminator is blocked by the adaptor ring or twin flash unit and cannot be used for focusing.

Selecting Apertures in TTL Flash
- The following tables show values when ISO 100 is used without the wide panel or diffuser. For other ISO speeds, or if you use the wide panel or diffuser, adjust the aperture settings according to the tables on page 28.
- The aperture ranges given in the tables are calculated values. The actual lens will have its own usable aperture range.
Example: Using a 50mm F2.8 Macro lens when ISO 100, with a pair of twin flash units with no arm, at a magnification ratio of 1:1
→ The range of acceptable apertures is calculated to be from f/4 to f/90 (refer to the following table).
However, the lens aperture range is f/2.8 to f/32, so the actual range possible with this lens is f/4 to f/32.
- The following tables show data for certain lenses and magnification ratios. For other lenses and magnification ratios, see page 54.

Using the f/stop scale at the left, moving one step vertically is equal to a full-stop change. Moving one step diagonally is equal to a half-stop change.
Half a stop is basic for setting the aperture in this step. When using a 0.3 stop setting camera, adjust the aperture by a value as close as possible to a value in the above table and use the aperture around the f/stop scale.
For precise photography, bracketing is recommended.
Example:
Starting at f/8, if you decrease the exposure by a full stop, you get f/11. If you increase by half a stop, you get f/6.7.
Selecting the aperture when using other than ISO 100, or when using the wide panel or diffuser
1 Check the calculated acceptable aperture range under the same condition with ISO 100 by using the table on page 27.
2 Check the additional adjustment when using other than ISO 100 or when using the wide panel or diffuser by using the table on page 28.
3 Check the calculated acceptable aperture range by using the f/stop scale using the results of step1 and step2.
4 Apply the result of step3 to the actual aperture range for this particular lens and select the usable range for satisfactorily results.
Example: Using a 50mm F2.8 Macro lens, two twin flash units, no arm, magnification ratio of 1:2, and ISO 200
1 Check the calculated acceptable aperture range when using a 50mm F2.8 Macro lens, two twin flash units, no arm, magnification ratio of 1:2, and ISO 100.
→f/8 - f/180 (refer to the table on page 27)
2 Check the additional adjustment when using ISO 200 and diffuser by using the table on page 28.
→Increase the aperture by +1.5 stops (refer to the table on page 28).
3 The aperture increased by +1.5 stops from f/8 is equal to f/4.5, and the aperture increased by +1.5 stops from f/180 is equal to f/108.
4 The ac tual aperture range for a 50mm F2.8 Macro lens is f/2.8 - f/32, so the upper limit of the adjusted f/4.5 - f/108 range, i.e. f/108, is beyond the range that can be set. The usable range for satisfactorily results is therefore f/4.5 - f/32.
Program auto flash (The basics)
The procedure for P mode, including subject program selection, is the same as that for A or M mode, except that the aperture is set automatically.
1 Set the POWER switch of the camera to ON and select P mode.
2 Press the flash ON/OFF button to turn on flash-ON lamp on the control panel.

3 Focus your subject and check the magnification ratio.
4 Select the flash.

5 When the macro flash controller is charged, press the shutter button to take a photo.
- With some cameras, the flash will fire automatically in P mode. In this case, the auto lamp on the macro flash unit comes on and the flash may not fire if the surrounding conditions are bright.

- The P mode flash program is designed for general subjects, not macro subjects. When taking macro photos, the depth-of-field may be very shallow. If the aperture selected by the camera is outside the allowable range, the proper exposure cannot be obtained (p. 26 - 29).
Manual flash (M)
Normal TTL flash metering automatically adjusts the flash intensity to provide the proper exposure for the subject. Manual flash provides a fixed flash intensity irrespective of the brightness of the subject and the camera setting.
- In manual flash mode, the maximum flash power is when the manual flash control is set to 1/1. Each step of the flash power level corresponds to one aperture stop. Changing the setting by one stop, for example from 1/1 to 1/2, is equivalent to decreasing the aperture one stop, for example from f/4 to f/5.6.
- Manual flash can only be used when the camera is in the M mode. In other modes, TTL measuring is automatically selected.
- As manual flash is not affected by the reflectivity of the subject, it is convenient for use with subjects with extremely high or low reflectivity.

3 Select shutter speed and aperture (p. 34 - 39).
4 Turn the appropriate manual-flash-control dial and select the desired power level (p. 34 - 39).
- When viewed from the rear (control panel side), the manual-flash-control dial for twin flash A is on the left, and that for twin flash B is on the right. You can select any power level setting on the upper scale from 1/1 to 1/64.

- In manual flash mode, if a proper exposure has been obtained, the flash-ready lamp will not blink on the control panel after a photo is taken.
- Using customized functions, manual flash may be selected without setting the camera in M mode. The size of the steps on the manual-flash-control dials can also be changed from full-stop increments to half-stop increments (p. 48).

Selecting apertures and power level in manual flash
- The following tables show the values when ISO 100 is used without the wide panel or diffuser. For other ISO speeds, or if you use the wide panel or diffuser, adjust the aperture settings according to the table on page 38. When using the twin flash units, the data assumes that the power lever is the same for both units. If they are set at different power levels, see page 37.
- The aperture values given in the tables are calculated values. The actual lens will have its own usable aperture range.
Example: Using a 50mm F2.8 Macro lens when ISO 100, with a pair of twin flash units with no arm, power level of 1/1, and a magnification ratio of 1:1
→ The aperture is calculated at f/90 (refer to the following table). However, the smallest actual aperture possible with this lens is f/32. Therefore, if you set the power level to 1/1, the picture will be overexposed. But if you set the power level to 1/8, you will get a correct exposure at f/32.
- These following tables show the apertures where the proper exposure of the illuminated area is obtained. Actual exposure varies according to the subject's shape or position (p. 53). Test photographs or bracketing is recommended especially when the subject is illuminated from side or behind.
- The following tables show data for certain lenses and magnification ratios. For other lenses and magnification ratios, see page 55.

Use aperture values inside ( ) when only one twin flash unit is used.
When twin flash units are at different power level settings
The values given in the preceding tables for the twin flash units assume that both twin flash units are set at the same flash level.
When they are set to different flash power levels, the aperture needed for correct exposure can be calculated using the following equation:
Aperture*
$$ = \sqrt {(\mathrm{Aflashaperture}) ^ {2} + (\mathrm{Bflashaperture}) ^ {2}} $$
Example:
Using a 100mm F2.8 Macro lens with a pair of twin flash units with no arm, "A" flash is set at a power level of 1/8, "B" flash unit is set at 1/16, and the magnification ratio is 1:1
The A flash aperture set at a power level of 1/8 is f/19 and the B flash aperture set at a power level of 1/16 is f/13 (refer to the table on 36 page).
Apply these results in the above equation.
$$ \sqrt {1 9 ^ {2} + 1 3 ^ {2}} = \sqrt {3 6 1 + 1 6 9 = 5 3 0 2 2} \quad \div $$
Therefore, in the above example, an aperture setting of f/22 will give proper exposure.
* When both twin flash units are used.
When using other than ISO 100, or when using the wide panel or diffuser
An additional adjustment must be applied to the previous tables.
| Without wide panel or diffuser (Exposure adjustment) | With wide panel (Exposure adjustment) | With diffuser (Exposure adjustment) | |

Using the f/stop scale at the left, moving one step vertically is equal to a full-stop change. Moving one step diagonally is equal to a half-stop change.
Half a stop is basic for setting the aperture in this step. When using a 0.3 stop setting camera, adjust the aperture by a value as close as possible to a value in the above table and use the aperture around the f/stop scale.
For precise photography, bracketing is recommended.
Example:
Starting at f/8, if you decrease the exposure by a full stop, you get f/11. If you increase by half a stop, you get f/6.7.
Selecting the aperture when using other than ISO 100, or when using the wide panel or diffuser
1 Check the calculated acceptable aperture under the same condition with ISO 100 by using the table on pages 35 and 36.
2 Check the additional adjustment when using other than ISO 100 or when using the wide panel or diffuser by using the table on page 38.
3 Select the c calculated acceptable aperture by using the f/stop scale using the results of step1 and step2.
Example: Using a 100mm F2.8 Macro lens, two twin flash units, no arm, a power level of 1/4, magnification ratio of 1:1, ISO 200 with the diffuser
1 Check the calculated acceptable aperture when using a 100mm F2.8 Macro lens, two twin flash units, no arm, a power level of 1/4, magnification ratio of 1:1, and ISO 100.
→f/38 (refer to the table on page 36)
2 Check the additional adjustment when using ISO 200 and diffuser by using the table on page 38.
→Increase the aperture by +1.5 stops (refer to the table on page 38).
3 The aperture increased by +1.5 stops from f/38 is equal to f/22.
Test flash
You can try one test flash before shooting. Use test flash mode when using a flash meter in manual-flash mode.
1 Press the TTL/M/Test button to turn on the test-flash lamp ♣.
Each time the TTL/M/Test button is pressed to change the TTL and M lamp be sure to check that the appropriate lamp is on. (See page 33 for the display sequence.)

2 Press the TEST button (test/modeling flash button).

- With TTL flash metering, the test flash will fire at full power when the TEST button is pressed.
- In manual flash mode, the test flash will fire at the selected power level when the TEST button is pressed. When using a flash meter, use manual flash mode.
Modeling flash
You can try continuous flash to check for shadows on the subject before shooting. The flash will fire for two seconds at a rate of 40 flashes per second.
1 Press the TTL/M/Test button to turn on the modeling-flash lamp.
Each time the TTL/M/Test button is pressed to change the TTL and M lamp be sure to check that the appropriate lamp is on. (See page 33 for the display sequence.)

2 Press the TEST button (test/modeling flash button).

- Do not press the shutter button while the flash is in use.
- The strength of shadows will differ from that during actual photography.
- When using the flash in a bright place or outdoors or when using a bounce flash, shadows are lighter so verification is more difficult.
Wide panel
The twin flash unit has a coverage of 60^ horizontally and 45^ vertically (equivalent to a lens with a 35mm focal length). By attaching the wide panel, the angles are increased to 78^ horizontally and 60^ vertically (equivalent to a lens with a 24mm focal length).

Attaching the wide panel
1 Check the front side of the wide panel.

2 Align the lower edge of the wide panel to the projection on the side of the flashtube and press the wide panel.
Press the wide panel until it clicks into place.

Compatibility with other products
Lens
- 49 mm and 55 mm adaptor rings are supplied.
- Lenses whose barrels rotate when auto-focusing cannot be used.
- When a wide angle lens is used, part of the holder may appear in the image. Do not use lenses whose focal length is shorter than 24 mm. If the focal length is between 24 mm and 27 mm, contact an authorized Sony dealer.
- If using a filter at a focal length of less than 50 mm, part of the holder may appear in the image.
Notes on use
While shooting
- This flash unit generates strong light, so it should not be used directly in front of the eyes.
Batteries
- Do not store the macro flash controller with the alkaline batteries inside it. Leakage from the batteries may damage the battery chamber.
- Depending on the temperature or storage conditions, the battery level displayed may be lower than the actual battery capacity. The displayed battery level is restored to the correct value after the flash has been used a few times. When lamp blinks to indicate that the flash cannot be used, pressing the flash ON/OFF button a number of times may result in restoration of the correct battery level display. If the battery level is still not restored, replace the battery.
- When using lithium batteries, if the batteries become hot due to high temperature or continuous use, lamp may blink and the flash may not work for a while. Wait for the batteries to cool down before using the flash again.
- Nick el-metal hydride batteries can lose power suddenly. If lamp starts blinking or the flash can no longer be used while taking pictures, change or recharge the batteries.
- The flash frequency and number of flashes provided by new batteries may vary from the values shown in the table, depending on the time elapsed since manufacture of the batteries.
Continuedonthenextpage
Temperature
- The flash unit may be used over a temperature range of 0 °C to 40 °C .
- Do not expose the flash unit to extremely high temperatures (e.g. in direct sunlight inside a vehicle) or high humidity.
- To prevent condensation forming on the flash, place it in a sealed plastic bag when bringing it from a cold environment into a warm environment. Allow it to reach room temperature before removing it from the bag.
- Battery capacity decreases at colder temperatures. Keep your camera and spare batteries in a warm inside pocket when shooting in cold weather. □ lamp may light on even when there is some power left in the batteries in cold weather. Batteries will regain some of their capacity when warmed to normal operating temperature.
- This flash unit is not waterproof. Be careful not to bring it into contact with water or sand when using it at the seashore, for example. Contact with water, sand, dust, or salt may result in a malfunction.
Maintenance
Remove this unit from the camera. Clean the flash with a dry soft cloth. If the flash has been in contact with sand, wiping will damage the surface, and it should therefore be cleaned gently using a blower. In the event of stubborn stains, use a cloth lightly dampened with a mild detergent solution, and then wipe the unit clean with a dry soft cloth. Never use strong solvents, such as thinner or benzene, as these damage the surface finish.
