To be honest my setting were not set to what I would of liked them to be. 1/1250 - f13 - ISO 1000, but it worked, go figure, I guess f13 at that focal length and distance works great. I did not adjust the sharpening in Lightroom. It is set to 40, no adjustment. It was the case of first shot of the day and not prepared in coming up on the bird. I was more involved in cropping the shot in camera and getting just the shot. I should have been more aware of my setting. I took this shot as I was walking up the stairs of the observation tower at the Loxahatchee Refuge. I try not to take photos of animals or birds with man made objects. He was on the hand rail of the stairs, so I cropped in camera to exclude the tower’s hand rail. The D850 finder is very accurate. I did crop a little from the sky on the top and sides in post. I did adjust the lens with Tamrons tap-in consol. I don’t have this lens anymore, I’m using the Nikon 200-500 and the 300pf now. I hope to get the 500pf in the future.
