There is, of course, that focus test floating around on the net — the one that uses an inclined bar chart. The shot is focused at the center, and then you can see the extent of the dof in graduated markings.
This D7000 shot was focused under ideal circumstances: bright, bright sunlight, tripod, 1/50 sec, f7+, cw metering. AF, of course. I took the image in less than 30 seconds of setup time using the superb 60mm f2.8 G Micro lens. One of Nikon's best. Expand the image and you'll see the fine casting marks from the sand mold in the metal.
But you want metrics. Next time I'll shoot a macro of a tape measure. Ha, ha.
