Recently I have shot some great white egrets in the wetland near my home. I have taken two lens, Nikon Z800mm/f6.3 & Z400m/f4.5. They are not heavy so I can take both at the same time. I attach Z800 lens to Z8 camera, and Z400 lens to Z9 camera. I love the combo when I do wildlife photograph. These photos are the output from the combo.
