My AF test results from today
In reply to wl7, Apr 15, 2012

This afternoon, I assessed the AF system of my D800 more systematically with the 85/1.4G. All images shot at f/1.4, SS 1/100, ISO 400.

Below is the compilation of photos. Sorry for the presentation. Not as polished as yours.

Camera on tripod, 8 ft away from target (Nikon D800 box) with MUP and cable release.

Defocus and focus before each shot using AF-S mode.

All 11 AF points from Row 3 (focus points 1 through 11, left to right). Camera swiveled on ballhead.

1 Trial only.

S/N: 300XXXX

Presently, I don't have access to my fast WA lenses (lent to a buddy for his trip), but will share my findings when I can, since those were the ones primarily giving me fits with OOF images.
