Shooting

• When the built-in flash is used in J mode, the shutter speed 

automatically changes over a range from 1/180 seconds 

to a slow shutter speed depending on the lens being used. 

The shutter speed is locked at 1/180 seconds when a lens 

other than a DA, DA L, D FA, FA J, FA or F lens is used.

• When the built-in flash is used in I, K or L mode, any 

desired shutter speed of 1/180 seconds or slower can be set.

• The built-in flash is optimum for a subject at a distance from 

approx. 0.7 m to 5 m. Vignetting may occur when used at 

a distance closer than 0.7 m (this distance varies slightly 

depending on the lens being used and the sensitivity setting).

• For details on the use of external flashes, refer to “Functions 

Set the focus mode switch to v 

or w.

The autofocus method for shooting with the viewfinder differs 

from that for shooting with Live View.

focus on the subject. The f 

button operation can be set
