Northern Pintail

This was taken on my first day out with the D500. I used a 1.4 teleconverter even though I didn't really need that much reach since the DX sensor got me close enough to my subjects. I wanted to test if the 200-500, 1.4 and the D500 would be useable for flight shots. I mostly photograph ducks in the Winter and the occasional Willet/Curlew/Godwit so I can't speak for smaller birds that would be more of a challenge to capture, but for my personal use, I'm very satisfied with the results. Btw, the pintail was too close to the background so it's not as smooth as I would like.
D500, 1.4TC, 200-500, 1,2000sec, f8 @ ISO 450. Thanks for looking and for your comments.
