Those are incredible! I don't suppose you would want to share how you captured so much detail on them?
Thanks. I got as close as I could without being too close for my Nikon 300mm f4 VR PF lens to focus. Little more than five feet. On Nikon D500. I use Topaz Detail software to sharpen. Had to wait patiently for the hummingbird to face me, with sun behind me, to get the red throat. Took a couple hundred shots and kept only the sharpest ones.
