Nature photographer Marco Valk used a Lumix GH5 and a Soundshark parabolic microphone (Premium kit) to capture this video of screaming bald eagles. He estimated the distance to be 200+ meters but the audio delay indicates the distance may actually be much greater. The effective focal length was 1960mm. In his words “Impressive sound! (straight from the camera)”.
The first thing Mr. Valk mentioned, upon receiving his Sound Shark in the Netherlands, was how much it reduced his wind noise. Check out Marco’s Facebook page, his Youtube channel, and his gallery.
