Press the 

M button and rotate the main command dial until the desired flash mode is 

displayed in the control panel.

The current flash mode is displayed in the control panel as shown below.

Normally the flash fires as the shutter opens (“front-curtain sync”; see below at left). In rear-
curtain sync, the flash fires just before the shutter closes, creating the effect of a stream of light 
behind moving subjects.

M button

Y (red-eye reduction): Use for portraits. Red-eye reduction lamp lights 
before flash fires, reducing “red-eye.”

j (off): Flash does not fire even when lighting is poor or subject is back-lit.

: Shutter speed slows automatically to capture background 

lighting at night or under low light. Use to include background lighting in 
portraits.

: Flash fires just before shutter closes (see below). If 

this icon is not displayed, flash will fire immediately after shutter opens.

: When lighting is poor or subject is back lit, flash pops up 

automatically when shutter-release button is pressed halfway and fires as 
required.
