ISO Speed During Manual Exposure Shooting
With [Auto] (A), the ISO speed will be set automatically within ISO
100- ISO 6400. Under [z3: ISO speed settings], if you set [ISO speed range]’s [Maximum] setting to [12800/H] (p.123), the maximum ISO speed will be expanded and the ISO speed will be set automatically within ISO 100 to H (equivalent to ISO 12800).
You can set the ISO speed manually within ISO 100 - ISO 6400 in
If [z4: Highlight tone priority] is set to [Enable] (p.145), the ISO speed will be ISO 200 - ISO 6400 (depending on the [ISO speed range] setting).
Under [z3: ISO speed settings], [Auto ISO range] or [Min. shutter spd.] cannot be set (p.124, 125) for movie shooting.
Since shooting a movie at ISO 8000/10000/12800 may result in much noise, it is designated as an expanded ISO speed (displayed as [H]). Under [ISO speed range], if [Maximum] is set to [H (25600)] and you switch from still photo shooting to movie shooting, the maximum ISO speed for the manual ISO range during movie shooting will be H (equivalent to ISO 12800). It cannot be expanded to ISO 25600. 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 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 fluorescent or LED lighting, image flicker may be recorded.
When Auto ISO 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 (p.22, 258) compared to when the <A> button was pressed.
By pressing the <B> button, you can display the histogram.
