10. Recording Motion Pictures
Applicable modes: 
Focusing changes depending on the Focus Mode setting 
 and the [Continuous AF] 
setting in the [Motion Picture] menu.
The interchangeable lens (H-H020A) utilizes a lens drive system to realize a compact and 
bright F1.7 lens. As a result, sound and vibration may occur during focus operation, but this is 
not a malfunction.
Depending on the recording conditions or lens used, operational sound may be recorded when 
the Auto Focus is operated while recording a motion picture.
It is recommended to record with [Continuous AF] in the [Motion Picture] menu set to [OFF], if 
the sound of operation bothers you to avoid recording the lens noise.
When operating the zoom when recording motion pictures, it may take time to come into focus.
When the interchangeable lens (H-H020A) is used, [AFF] and [AFC] cannot be set.
