On	Adjusts the focus by pressing the shutter button halfway
	down.

	center of the multi-selector. This is convenient when shooting
	continuously at the same focus position.

Long exp.NR

Long exposure makes noise conspicuous. When the shutter speed is one second or slower, noise reduction is activated to reduce the grainy noise that is common in long exposures.

On	When the shutter speed is one second or slower, the noise
	reduction process is performed for the duration that the
	shutter was open. You cannot take the next picture until the
	process is over. This is suitable when the image quality takes
	precedence.
Off	This mode does not perform noise reduction. This is suitable
	when timing of shooting takes precedence.

Note

•Noise reduction is not performed on continuous shooting or continuous bracket even when it is set to [On].

High ISO NR

When shooting with the ISO set at 1600 or above, the camera reduces the noise that becomes more noticeable when the camera sensitivity is high.

High	When [High] is selected, the noise reduction works more
	effectively. When you give priority to the details of a subject,
Normal
	select [Low].
Low
Off	Does not reduce noise.

Note

• The speed of continuous shooting becomes slower when set to [High].
