Hummers, 5/10/2020 - I set up my D5 with the Nikkor 500mm f5.6E-PF to make photos of Orioles.
This little Hummer came in, hovering, move in and back out, took several stops to suck nector while hovering.
I ripped off 190 RAW-NEF images in 17 seconds, the busy light went off instantly. Amazing camera, get yourself a D5!!
Also, I had 4 out of focus images, a dozen acceptable and all others are smack on sharp viewed on my big monitor.
