Re: D800 fine focus adjust πŸ€”

Try this.

Attach a strip of coloured tape to a white wall.

With single point AF using AF-C aim the camera at the white wall, keep first pressure on the shutter and wait about 1.5 seconds for AF to stop hunting, then keeping first pressure on the shutter move the viewfinder slowly toward the tape - and AF should stay before the AF point reaches the edge of the tapeΒ 

This demonstrates the D800 AF can lock on something outside the viewfinder rectangle.

With a 45 degree ruler, if you start AF from infinity, AF can lock on the first ruler line it detects within the depth of field - which is unlikely to be the 30 line you intended.

This is why a ruler at the side of an AF target is better - though there can still be moderate issues if the lens has a curved field.

In lots of ways good photography is much more about how equipment is used rather than anything else.
