Under [54: Custom Functions (C.Fn)], if[2: ISO expansion] is set to [1: On], the manual setting range willexpand 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 isdesignated as an expanded ISO speed (displayed as “H”).If ISO speed is set to H (ISO 25600) when [2: ISO expansion] is set to[1: On] under [54: Custom Functions (C.Fn)] and you switch from stillphoto shooting to movie shooting, the ISO speed will be H (equivalent toISO 12800). When you switch back to still photo shooting, the ISO speedwill be ISO 12800.Exposure compensation cannot be set.Changing the shutter speed or aperture during movie shooting is notrecommended since the changes in the exposure will be recorded.If you change the shutter speed while shooting under fluorescent or LEDlighting, image flicker may be recorded.When ISO Auto is set, you can press the <A> button to lock the ISOspeed.If you press the <A> button and recompose the shot, you can see theexposure level difference on the exposure level indicator (p.239)compared to when the <A> button was pressed.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 lesssmooth the subject’s movement will look.
