However, I notice something that I haven't seen being brought up.

1. After I focused with LV, I hit the button to switch back to view finder. In this process, it seems like there are enough camera shake that the focus is already off. (I test it by immediately switch back to LV and found that the green rectangle turned red.) I tried to reduce the camera shake by putting a sand bag on top of the D800, but it doesn't seem to help enough to avoid that issue.

What kind of tripod and head are you using? Pressing the LV button should not move the camera far enough to alter focus.
