 Shooting Movies

 

The procedure is the same as steps 3 
and 4 for “Autoexposure Shooting” 
(p.174).

 

With [Auto], the ISO speed will be set automatically within ISO 100 - 
ISO 6400.

 

You can set the ISO speed manually within ISO 100 - ISO 6400 in 
whole-stop increments. Under [54: Custom Functions (C.Fn)], if 
[2: ISO expansion] is set to [1: On], the manual setting range will 
expand so you can also select H (equivalent to ISO 12800).

 

Under [54: Custom Functions (C.Fn)], if [3: Highlight tone 
priority] is set to [1: Enable], the ISO speed will be ISO 200 - ISO 
6400.

 

Since shooting a movie at ISO 12800 may result in much noise, it is 
designated as an expanded ISO speed (displayed as “H”).

 

Under [54: Custom Functions (C.Fn)], if [2: ISO expansion] is set to 
[1: On] and you switch from still photo shooting to movie shooting, the 
manual setting range’s maximum will be H (equivalent to ISO 12800). 
Even if you switch back to still photo shooting, the ISO speed will not 
revert to the original setting.

 

Exposure compensation cannot be set.

 

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

 

If you change the shutter speed while shooting under fluorescent or LED 
lighting, image flicker may be recorded.

 

When ISO Auto is set, you can press the <A> button to lock the ISO 
speed.

 

After recomposing the picture, you can see the exposure level difference 
on the exposure level indicator (p.179) compared to when you pressed 
the <A> button.

 

By pressing the <B> button, you can display the histogram.

 

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.
