 Setting the FlashN

Flash mode
When using an external Speedlite, you can select the flash mode to 
suit your desired flash shooting.
 
[E-TTL II] is the standard mode of 
EX-series Speedlites for automatic 
flash shooting.
 
[Manual flash] enables you to set the 
flash output yourself. This is for 
advanced users.
 
Regarding other flash modes, refer to 
the instruction manual of an external 
Speedlite compatible with the 
functions.
 
Shutter synchronization
Normally, set this to [1st curtain] so that the flash fires immediately 
after the exposure starts.
If [2nd curtain] is set, the flash will fire right before the shutter 
closes. When this is combined with a slow shutter speed, you can 
create a trail of light such as from car headlights at night. With E-TTL 
II (autoflash exposure), two flashes will be fired: Once when you 
press the shutter button completely, and once immediately before 
the exposure ends. Also, with shutter speeds faster than 1/30 sec., 
1st curtain synchronization will automatically take effect.
If an external Speedlite is attached, you can also select [Hi-speed
(e). For details, refer to the Speedlite’s instruction manual.
 
Flash exposure compensation
See “Flash Exposure Compensation” on page 113.
 
E-TTL II flash metering
For normal flash exposures, set it to [Evaluative]. [Average] is for 
advanced users. As with an external Speedlite, the metering is 
averaged for the entire area. Flash exposure compensation may be 
necessary.
