This test doesn't seem practical. Using D153 for a subject that size? I could see that being useful for a bird against a clear blue sky, but in this test, you're using a shotgun to shoot an ant. In this situation 3D would've done what you wanted. Know, I know the D810 does... maybe that's wrong.
Here's an idea for a test to see if Dynamic Area does as described in the manual. I refer to a video or article that Steve had on checking the accuracy of the placement of an AF point, vs what's illuminated in the viewfinder.
Take a big piece of white paper with a little target test design in the middle.
In single AF point, determine the area or location of the actual AF point. Then go to D9 AF. Do the test again but as the main AF point goes off the test image and onto the white BG, one of the AF points surrounding it should still hold it in focus until you move away from the area that point can hold. The key here is (from the manual) - the camera will focus based on information from surrounding focus points if the subject briefly leaves the selected point.
In 3D mode. use the center AF point. As you pan away from the little test patter, the AF point will move and keep the test image in focus - it'll follow. English is my second language, but when I read the manual, that's what I gather. I don't know how or why the other bodies perform as people describe, but could it be that they aren't working properly as described?
