Note
When [ Quality] is set to [RAW] or [RAW & JPEG], [Multi Frame NR] cannot be selected.
When [Multi Frame NR] is selected, the flash, [D-Range Opt.], or [Auto HDR] cannot be used.
When [Picture Profile] is set to other than [Off], [Multi Frame NR] cannot be selected.
When [Picture Effect] is set to other than [Off], [Multi Frame NR] cannot be selected.
[ISO AUTO] is selected when using the following functions:

The higher the ISO value, the more noise will appear on the images.
The available ISO settings will differ depending on whether you are shooting still images, shooting
movies, or shooting slow-motion/quick-motion movies.
When shooting movies, ISO values between 100 and 25600 are available. If the ISO value is set to a
value larger than 25600, the setting is automatically switched to 25600. When you finish recording
the movie, the ISO value returns to the original setting.
When you use [Multi Frame NR], it takes some time for the product to perform the overlay processing
of images.
When you select [ISO AUTO] with the shooting mode set to [P], [A], [S] or [M], the ISO sensitivity will
be automatically adjusted within the set range.
Hint
You can change the range of ISO sensitivity that is set automatically in [ISO AUTO] mode. Select
[ISO AUTO] and press the right side of the control wheel, and set the desired values for [ISO AUTO
Maximum] and [ISO AUTO Minimum]. The values are also applied when shooting in [ISO AUTO]
mode under [Multi Frame NR].
You can set the effect level for noise reduction by selecting [NR Effect] under [Multi Frame NR].
