Photog here - this shutter speed is perfectly reasonable.

Remember the photog is against the brightness of the clear blue, sunny sky behind the subjects and needs to expose for the foreground too. A fast shutter speed helps do that.

If the camera is set to Aperture priority or indeed any setting which applies auto shutter-speed, this is not even slightly suspect.

Nothing here except wild, uninformed speculation.

*edit to add: the OP talks about 30fps - this is just utterly irrelevant for a still image
