Here are my first tries with the 500mm f/4 PF on D500 at Creamer's Field Migratory Waterfowl Refuge, a resting place for many birds migrating to the Arctic. It is cleared of snow each spring and grains spread over the field to welcome our winged friends. The bulk of the Trumpeter swans (Cygnus buccinator) had already continued on up north, but a single couple were still hanging around. Other species are White-fronted goose (Anser alifrons), Canada goose (Branta canadensis), American wigeon (Mareca americana), Northern pintail (Anas acuta), Northern shoveler (Spatula clypeata) and Snow goose (Anser caerulescens). While the first ones were captured with the lens wide open which is ideal, I used TC-14E at f/9 for a while (#5 and 6 + #1 in next post) and forgot to set aperture back afterwards. Shutter speeds were on the long side for some of the BIFs after this. (Open images in new tab for larger versions, continues in next post.)[
