Turning on/off the AF Assist Lamp
→ [Custom] → [AF Assist Lamp] → [ON] / [OFF]
The AF Assist Lamp lights up when the shutter button is pressed halfway when it is too
dark to allow focusing. (A large AF area is displayed based on recording conditions.)
●
The AF Assist Lamp has an effective range of approx. 1.5m (5 feet).
●
The AF Assist Lamp is only effective for a subject in the center of the screen.
Remember to position your main subject in the center when the AF-Lamp lights up.
●
If you do not want the AF Assist Lamp to light up when you take a picture in a dark
location (e.g. taking a picture of an animal in the dark), set this function to [OFF]. When
the AF Assist Lamp is set to [OFF], focusing will become difficult.
●
The setting is fixed to [OFF] in the following case:
• When [Silent Mode] is set to [ON]
Enabling/disabling recording when a subject is out of focus
→ [Custom] → [Focus/Release Priority]
[FOCUS]: The shutter release button is locked unless focusing is successful.
[RELEASE]: Releasing the shutter is always possible, regardless of whether the subject
is correctly focused or not. This helps to avoid missed opportunities.
●
Note that a picture may be out of focus when [RELEASE] is set, even if the focus mode
is set to [AFS], [AFF], or [AFC].
●
This function is disabled during motion picture recording.
Enabling/disabling manual focusing after AF
→ [Custom] → [AF+MF] → [ON] / [OFF]
You can perform manual focusing during AF Lock (pressing the shutter button halfway
when [AFS/AFF/AFC] is set to [AFS] or setting AF Lock using the [AF/AE] button).
