7. Flash
∫ The available flash range (approximation)
When you use certain lenses, light from the flash may be 
blocked or fail to cover the lens field of view, causing dark 
areas to appear in the resulting pictures.
The distance at which light from the flash is blocked by lens, and 
the distance to which light from  the flash is delivered vary 
depending on the lens used.
•
The ranges are those of when the ISO sensitivity is set to [AUTO] and [ISO Limit Set]  (P133) is 
set to [OFF].
•Observe the following points. Not doing so may cause the camera to deform, discolor or 
malfunction.
–Do not bring objects too close to the flash.–Do not close the flash while it is firing.
–When using a setting that uses a pre-flash, such as [Forced On/Red-Eye], do not close the 
flash immediately after the camera emits a pre-flash.
•It may take time to charge the flash if you repeatedly take pictures. You must wait a moment to 
take the next picture while the flash icon is blinking red indicating the flash is charging. Take a 
picture after the access indication disappears.
•When you attach an external flash, it takes priority over the built-in flash. Refer to  P347 for the 
external flash.
•In the following cases, the flash is fixed to [ Œ] (forced flash off).–When recording motion pictures
–When [Electronic Shutter] is set to [ON]–When [HDR] is set to [ON]–When [Silent Mode] is set to [ON]

Taking Pictures with Wireless Flashes
By using flashes that support the wireles s control (DMW-FL360L, DMW-FL580L: optional), 
you can control firing of the built-in flash (or  a flash attached to the hot shoe of this unit) 
and three flash groups separately.
1Set the wireless flashes to RC Mode and then place them.
•Set a channel and groups for the wireless flash.
2Press the flash button to open the built-in flash or attach a flash 
(DMW-FL360L or DMW-FL580L: optional) to the camera.
3Select the menu.  (P54)

∫ Placing wireless flashes
Place the wireless flash with its wireless sensor facing toward the camera.
The following figure shows the estimated cont rollable range when you take pictures by 
holding the camera horizontally. Controllable range differs depending on the surrounding 
environment.
Placement example
•
In this placement example, flash C is placed to erase the shadow of the subject that flashes A 
and B will create.
•The recommended number of wireless flashes for each group is three or less.•If the subject is too close, signal flashing may affect the exposure.
If you set [Communication Light] to [LOW] or lower the output with a diffuser or similar product, 
the effect will be reduced.
