Re: DotTune: Video Tutorial for AF tuning without photographs

If I use Lens Align to set focus then look at the slanted ruler. The optimum centre focus value is NEVER in the centre of the DOF.

So how can this method which assumes the centre of the confirmation range is correct actual be accurate?
