In my experience the only way to assure critical focus is tethered on a laptop. All other methods will get you close most of the time, but the LCD's on my D800E and Canon 5Dmk3, 1Ds3, are just not good enough for critical work especially when the focus shifts when stopped down. As sensors get better and lenses get sharper - our out of focus shots look worse than ever, or at least they feel that way...I find that focus peaking is great for getting the focus in the ballpark, but for critical focusing accuracy I want a 4x to 10x magnification (depending upon focal length) without peaking turned on (just like I used to do with an optical ground glass and a magnifier). Being able to target the center of the zoom area has been a major boon for static work that requires critical focus, for me anyway.
