ISO 12800. The maximum limit varies depending on the

ISO Auto] setting ( = 254). Note that when the
camera is set for 4K movies, ISO speed is ISO 100–ISO 6400.

You can set the ISO speed manually within ISO 100–ISO 12800 in
whole-stop increments. Under [

set [ISO expansion] to [1:On] , the maximum limit of the manual
ISO speed setting range will be expanded so you can also select H
(equivalent to ISO 25600). Note that when the camera is set for 4K
movies, ISO speed is ISO 100–ISO 6400.
z
If [
z
: Highlight tone priority] is set to [Enable] , the ISO speed
will be ISO 200–ISO 12800. Note that when the camera is set for 4K
movies, ISO speed is ISO 100–ISO 6400.

is designated as an expanded ISO speed (displayed as “ H ”).

settings again before shooting movies.

Changing the shutter speed or aperture during movie shooting is not
recommended since the changes in the exposure will be recorded.

When shooting a movie of a moving subject, a shutter speed of approx.
1/30 sec. to 1/125 sec. is recommended. The faster the shutter speed, the
less smooth the subject’s movement will look.

lighting, image flicker may be recorded.
