I had an odd thing happen today. I was making some test shots with the 50MP, and found that I couldn't focus where I wanted. I tried the center of the view, no problem. Tried again a bit lower and to the left, and again missed, by quite a bit. I tried both with and without the focus point assistance, but I just couldn't focus in that part of the photo. Very weird, and I can't explain it. I tried in other parts of the image, no problem. Just for some reason, for this one composition I couldn't get the focus right.
Has anyone experienced anything like that? What could it be, field curvature? It wasn't that far out in the field, just perhaps at the 1/3, 1/3 mark, from the bottom left. I was shooting wide open, Nikon D3.
I have a weird picture from 50MP, but it was shot through a windshield, which may have contributed to that effect. Here is a 100% off center crop from a shot with a focal plane somewhere near the traffic lights. Notice that the traffic lights are more or less in focus, the building right behind is out of focus (shot at f/4.5), but the building in the back appears sharp again...
