I am not a very good bird photographer. I know a number of my friends who excel at bird photography. While in Japan leading a workshop in 2019 I gave some bird photography a try. I had some good results. Today I am much better as I have a Sony a9 (soon to be a1) That focuses so fast and shoots for many frames a second that I would have to be an idiot not to get a good shot. These were shot with a Fuji XT4 and 100-400mmm lens. The Fuji while good nowhere compares to my Sonys. No matter what though it was shooting these.
