IMPORTANT: If you change the aperture value while recording movies, a clicking sound may be heard but this is not a malfunction.
If the clicking sound is noticeable, we recommend that you use an external microphone, set Audio Recording to Off, or adjust Audio Rec Level.
Set the mode dial to (Movie).
Press the Fn button and select (Aperture Priority) or (Manual Exposure).
Set the desired aperture value using the aperture ring while shooting.
NOTE: When you adjust the aperture while recording a movie, set the Aperture Click Switch to OFF .
