Overcast skies, later in the afternoon and sometimes fast moving birds. all not the best arguments to have tac sharp images and low ISO and fast shutter speed. So I decided to go high in ISO, 4000 and sometimes way more, in order to keep shutter speed low to catch where possible the action. In post I could eliminate some of the noise, but in most photos I just kept it as it came out of the camera.
Camera used : Sony A7R4 with a 200-600mm lens
