I wanted to say you've got some great images here. I doubted the veracity of your technique, but based on these photos it obviously is working well for you. I'm still not convinced MF is better for larger targets and not for flight shots but I certainly can't say it doesn't work. For my part I'll stick with AF for the larger birds when I do shoot. It's been working for me with the little I do of birding. But hats off to you on some excellent shots! Please accept my public apology for calling you out. I can see you do indeed know what you're talking about with wildlife photography! Thanks for sharing.
