• a sound pickup section operable to pick up sound used to generate audio data;
• and
• a sound processor operable to change a setting relating to a directionality of the sound pickup section in conjunction with a change of the zoom magnification of the interchangeable lens, wherein:
• the zoom range information is specific to the interchangeable lens and is pre-stored in the interchangeable lens, and the zoom range information includes information corresponding to a maximum magnification and a minimum magnification that can be provided by the interchangeable lens,
• the directionality of the sound pickup section can be changed between a first directionality by which a sound in the widest region can be picked up and a second directionality by which a sound in the narrowest region can be picked up,
• the sound processor sets a directionality of the sound pickup section corresponding to the minimum magnification of zoom indicated by the zoom range information to the first directionality, and sets a directionality of the sound pickup section corresponding to the maximum magnification of zoom indicated by the zoom range information to the second directionality, based on the zoom range information;
