Focus and exposure lock when the shutter button is pressed halfway.
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).
Press the button all the way down.
Focus and exposure lock via the shutter button is only available when [ON] is selected for D [BUTTON/DIAL SETTING] > [SHUTTER AF], [SHUTTER AE].
Focus and exposure can also be locked using function buttons. At default settings, you can use the [AEL] button to lock exposure without locking focus. If the [AFON] button is assigned [AF LOCK ONLY] (aFunction Controls), it can similarly be used to lock focus without locking 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 D[BUTTON/DIAL SETTING] > [AE/AF-LOCK MODE], the lock can only be ended by pressing the control a second time.
The focus lever (focus stick) can be used to reposition the focus point during exposure lock.
Function buttons can be assigned other roles using D [BUTTON/DIAL SETTING] > [FUNCTION (Fn) SETTING]. Exposure and focus lock can also be assigned to other function buttons (aFunction Controls).
