ISO Speed During Manual Exposure Shooting
With [AUTO], the ISO speed will be set automatically within ISO 100–
ISO 12800. The maximum limit varies depending on the [Max for Auto]
setting in [z:kISO 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 [5: Custom Functions(C.Fn)], if you
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.
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.
Since shooting a movie at ISO 25600 equivalent may result in much noise, it
is designated as an expanded ISO speed (displayed as “H”).
When switching from still photo shooting to movie shooting, check the camera
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.
If you change the shutter speed while shooting under uorescent or LED
lighting, image icker may be recorded.
If you set [5:Expo comp (hold btn, turn S)] with [Assign SET button]
under [5: Custom Functions(C.Fn)] (=
452), you can use exposure
compensation with ISO Auto set.
When ISO Auto is set, you can press the <A> button to lock the ISO speed.
If you press the <A> button and recompose the shot, you can see the
exposure level difference on the exposure level indicator (=
223) compared
to when the <A> button was pressed.
By pressing the <B> button, you can display the histogram.
