[AF ASSIST LAMP]
•
The effective range of the AF Assist Lamp is different depending on used lens.
–
When the interchangeable lens (H-H014) is attached: Approx. 1.0 m (3.28 feet) to 3.5 m
(11.5 feet)
–
When the interchangeable lens (H-FS014042) is attached and at Wide: Approx. 1.0 m
(3.28 feet) to 3.0 m (9.84 feet)
•
The AF Assist Lamp is valid only for the subject in the center of the screen. Use it by
positioning the subject in the center of the screen.
•
Remove the lens hood.
•
When you do not want to use the AF Assist Lamp (e.g. when taking pictures of animals in dark
places), set the [AF ASSIST LAMP] to [OFF]. In this case, it will become more difficult to focus
on the subject.
•
The AF Assist Lamp gets slightly blocked when the interchangeable lens (H-FS014042) is
used, but it does not affect the performance.
•
The AF Assist Lamp may be greatly blocked, and it may become harder to focus when a lens
with large diameter is used.
•
The setting for the [AF ASSIST LAMP] is fixed to [OFF] in [SCENERY], [ARCHITECTURE],
[NIGHT SCENERY] and [SUNSET] in Scene Mode.
