I have a Nikon 85 1.8G.
I have encountered this issue a few times now. When I am at a considerable distance away from the subject (ie. 20 feet), the lens deeply back focuses. I am not missing focus, I am steady and dead set on the eye. When I move closer, say 5 feet, lens is tack sharp and focus falls just where I intend.
Yesterday's example. I did a maternity shoot in a flower field. The flowers came up about thigh high. Focus was placed on the mother's face, several feet higher than the flowers. The background space behind her head was over 100 feet away. Shutter was at 320, light was excellent (sun at golden hour to the side falling beautifully on the face), plenty of contrast on the face. I took several full body shots at 2.8, zoomed in, and realized she was completely OOF. Focus fell on the flowers about a foot or two behind her. I recomposed, refocused, tried again and the same thing happened. There is no way I moved and caught the background behind her head accidentally because that was far behind the flowers and not in focus either.
This same thing has happened several times before in different locations.
So I moved closer to do half body shots and my focus fell perfectly on the eyes. This lens is already manually fine tuned/calibrated to my camera.
Am I missing something here?
