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 lock using the shutter button is only available when [ON] is selected for D [BUTTON/DIAL SETTING] > [SHUTTER AF], [SHUTTER AE].
Pressing the [AE-L]/[AF-L] button locks both focus and 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 [AE-L]/[AF-L] button 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 (aAssigning Roles to the Function Buttons).
Exposure and focus lock can be performed separately by assigning them to different function buttons.
