Common sandpiper / Strandsnipe (Nikon Z9 + 100-400mm) 

After having a issue with my Z9 and 200-500mm f/5.6 lens when recording video (the videos would turn soft and not sharp, and lack of details, I did not have the issue when using my Z6 II), I decided to get the new Z100-400mm lens. The 200-500 worked great for photos.
After trying it for while, I must say I really enjoy using the lens, and I really like the results I'm getting.
