Using the Sync Modes

This flash unit has the following sync modes. Select the mode
best suited for the subject.

Leading Curtain Sync Mode
This is the most commonly used sync mode. In this mode, the
flash is discharged at the instant the first shutter curtain
completes its travel. You can use this mode with the shutter
speed set to the X-sync speed or slower. Refer to page 31 for
this sync mode.

Trailing Curtain Sync Mode
In this sync mode, the flash is discharged at the instant the
second curtain begins its travel. This mode will freeze the
subject with a blur appearing after the subject under a slow
shutter speed condition. Refer to page 31 for this sync mode.

High-speed Sync Mode
This sync mode will enable flash synchronization with shutter
speeds faster than the X-sync speed. Since there is no sync
speed limitation, high-speed sync is effective for fill-flash in
daylight. Refer to page 32 for this sync mode.

Contrast Control Sync Mode
This sync mode enables you to photograph with multiple flash
units, utilizing the difference of the light intensity of each flash
unit to optimize the shadow of the subject. The ratio of flash
light intensity between the flash unit set to this sync mode and

3. Appendix

Flash Effective Range

n Calculating the Flash Effective Range
When setting the lens to manual F/stop, calculate the guide
number at full flash with the use of flash’s zoom position and
ISO. Divide the resulting guide number by the aperture in use.
Thus, the maximum distance is obtained. The minimum
distance is obtained in dividing this max. distance by approx.

10. However, if the minimum distance obtained is 0.7 m or less,

3

the minimum distance will be 0.7 m. Refer to page 58 for the
guide number table.

Example:
With an 85 mm lens at F/4 and sensitivity at ISO100
1 For the zoom position 58mm and sensitivity at ISO100,

the guide number is 54.

2 54 (guide number) /4 (aperture) = 13.5m (max. distance)
3 13.5m (max. distance) /10 = 1.35m (min. distance) Thus,

flash effective range is approx. 1.35m - 13.5m.

* The numbers used in this example are for K series (APS-C).

56

Effective flash range

Display of Effective Flash Range

The effective flash range will be displayed on the LCD panel of
this flash unit. Make sure that you are within the effective flash
range before taking pictures.

• The effective flash range is displayed for the following
camera and lens combinations.

Camera Lens Types
K series (APS-C) DA, D FA, FA J, FA, F, A
645D DA645, D FA645, FA645, A645
Q series Q Mount Lens

• The flash effective range varies depending on ISO, lens
aperture in use, and/or the zoom position (flash coverage
angle). Keep this in mind especially when you are using
a variable aperture zoom lens.

n Guide Number (GN)
Guide numbers indicate flash light intensity. The larger the
number, the farther you can reach with your flash. From the
guide number, you can easily obtain the proper aperture setting
required for an optimum exposure.

Aperture (F/stop) =

GN/flash-to-subject distance (m)

• Depending on the camera and lens you are using, the
effective flash range may be displayed. (Refer to page 57.)
