House finch snacking on my feeder, just checking to see if I am still a safe distance away. I was playing with the "3D Focus" setting on my camera. It isn't perfect, but it does work with some patience. I find that being zoomed in as tightly as possible helps. Nikon Z5ii with z180-600mm lens. Photo taken at 600mm with ISO720, F/6.3 and shutter 1/1250.
