The first closeup here is obviously a little too close. However there wasn’t a lot of time to be swapping lens when shooting a falcon
These were taken the first time I photographed a Peregrin in actual flight and falcon hunt. I did capture him in flight (above). But the hunt and catch, not even close. That took a lot more practice and photo shoots. See this post for a capture.
This day I learned just how fast, 240 mph, these guys can go when they want to. It took a few more exercise sessions before I figured out how to photograph them. Until then I had plenty of embarrassing blank photos.
