I got exactly one chance at this guy. He was out working hard and I was just getting off work. The manual focus/eyeball combination was disagreeing with Nikon’s autofocus indicators in the viewfinder. I went with my eye and it came out okay. I chimped the exposure and looked up, and he was off to the next flower. One shot.
I missed focus to the near side, by a couple of millimeters from a meter-ish away. I love this lens.
