Sony DSC-RX100M4 Instruction Manual page 100

Note
Under the following settings, the shutter speed is slower, so use of a tripod is
recommended to prevent the image from blurring:
[Night Scene]
[Night Portrait]
[Fireworks]
In the [Hand-held Twilight] or [Anti Motion Blur] mode, the shutter clicks 4 times and an
image is recorded.
If you select [Hand-held Twilight] or [Anti Motion Blur] with [RAW] or [RAW & JPEG], the
image quality becomes [Fine] temporarily.
Reducing blur is less effective even in [Hand-held Twilight] or [Anti Motion Blur] when
shooting the following subjects:
Subjects with erratic movement.
Subjects that are too close to the product.
Subjects with continuously similar patterns, such as the sky, a beach, or a lawn.
Subjects with constant change such as waves or water falls.
In the case of [Hand-held Twilight] or [Anti Motion Blur], block noise may occur when
using a light source that flickers, such as fluorescent lighting.
The minimum distance that you can come close to a subject does not change even if you
select [Macro]. For the minimum in-focus range, refer to the minimum distance of the lens
attached to the product.
Hint
To change the scene, rotate the control wheel on the shooting screen and select a new
scene.
[33] How to Use
Shutter Priority
You can express the movement of a moving subject in various ways by adjusting the shutter
speed, for example, at the instant of the movement with high speed shutter, or as a trailing
image with low speed shutter. The shutter speed can be changed while recording movies.
