Nikon D800 AF-S Autofocus Accuracy with Nikon 85mm f/1.4G
I have updated my Nikon D800 review to another example, this time with fifteen (15) attempts compared to magnified Live View with contrast-detect AF.
This example uses a dark but high contrast target. I expect and need autofocus to work accurately under such real-world conditions.
See my Nikon gear page for D800 availability status.
