Compose photographs with off-center subjects.
Position the subject in the focus frame and press the shutter button halfway to lock focus and exposure. Focus and exposure will remain locked while the shutter button is pressed halfway (AF/AE lock).
Keep the shutter button pressed halfway.
Press the button all the way down.
Focus lock using the shutter button is only available when ON is selected for DBUTTON/DIAL SETTING > SHUTTER AF, SHUTTER AE.
The focus lever (focus stick) can be used to reposition the focus point during exposure lock.
The AF-L and AE-L Buttons
Focus and exposure can also be locked with the AF-L and AE-L buttons. At default settings, the AF-L button locks focus, the AE-L button exposure.
While the assigned control is pressed, pressing the shutter button halfway will not end the lock.
If AE&AF ON/OFF SWITCH is selected for DBUTTON/DIAL SETTING > AE/AF-LOCK MODE, the lock can only be ended by pressing the control a second time.
