dave9t5: Thanks, I enjoyed Ming Thein's post very much. He also said he'd use a technique of continuous shooting with continuous little degree turning of the focus ring. Well, it's a solution, but imaging to sit there and decide at 100% the sharpest shot is nothing I enjoy doing in post.
dave's cliché©s: you're sure about "...PD systems can't cope with these extremely minimal DOFs"? Somehow I'd expect it very helpful for PD AF if a lens is as crunchy as the Zeiss or the Sigma wide open, when focus just jumps form "no!" into "Very yes!". I find my D810 to be coping pretty decent with the Sigma (and all other lenses, too). It' just a pity for the Zeiss, that these days nearly all focussing systems rely on software and are lacking mirror/matte screen accuracy. But with the D810, LiveView is now finally on par with all other good LV's. Even on the iPad vila CamRanger I see definitely the improvement I was waiting for.
