FE (flash exposure) lock locks the correct flash exposure reading for any part of 
the scene. After focusing the subject, you press the camera’s <7> button.

Press the <7> button.

Aim the subject at the center of the 
viewfinder and press the <7> button.

The Speedlite will fire a preflash and 
the required flash output for the 
subject is retained in memory.

7

 

The FEL display will be shown in the viewfinder for 0.5 sec.

 

Each time you press the <7> button, a preflash will be fired and the 
FE lock will be set again.

 

If the camera does not have a <7> button, press the <P> button.

 

If the subject is too far away and underexposure will result, the <Q> icon 
will blink in the viewfinder. Move closer to the subject and try the FE lock 
again.

 

If the subject is too small, FE lock might not be very effective.

With high-speed sync (FP flash), the flash can synchronize with all 
shutter speeds. This is convenient when you want to use aperture 
priority for fill-flash portraits.

Press the <F> button and the 
<F> lamp will light.

 

In the viewfinder, check that the <F> 
icon is lit.

F

 

If the flash exposure confirmation lamp does not light, move closer to the 
subject and take the picture again. With a digital camera, you can also 
increase the camera’s ISO speed.

 

If the shutter speed is slower than the maximum flash sync speed, <F> 
will not be displayed in the viewfinder.

 

With high-speed sync, the faster the shutter speed, the shorter the flash 
range will become.
