• When the capture mode is set to n (Stage Lighting), l (Night Snap) or Z
(Night Scene HDR) of H (Scene) mode, or when the mode dial is set to C
(Movie), the sensitivity is fixed to AUTO and cannot be changed.
• When the capture mode is set to K (Sensitivity Priority) or a (Manual),
[AUTO Setting] is not displayed.
• The sensitivity range can be expanded to a range of ISO 100 to 25600 when
[3. Expanded Sensitivity] in the [A Custom Setting 1] menu (p.89) is set to
[On]. However, the minimum sensitivity is ISO 200 when [Highlight
Correction] (p.207) is set to [On].

reduce image noise by setting [High-ISO NR] in the [A Rec. Mode 2] menu.

• You can select whether to set the sensitivity in increments of 1 EV or in
accordance with the EV step setting for exposure (p.118). This can be set in
[2. Sensitivity Steps] of the [A Custom Setting 1] menu (p.89).
Expanding the Dynamic Range
Dynamic range is the ratio that indicates the light level expressed by
the CMOS sensor pixels from bright areas to dark areas. The larger
it is, the better the whole range from dark to bright areas will appear
in the picture.
By expanding the dynamic range, you can expand the light level
expressed by the CMOS sensor pixels, making it more difficult for
bright area to occur in the image.
To expand the dynamic range, make the settings in [D-Range
Setting] of the [A Rec. Mode 3] menu. (p.207)
