Clark pointed out that I shot this pic at 1/60th, not 1/100 or faster. He was confsed, and so was I. I check my notes, and I did use a tripod for all of these shots. I also bracket my images, and I may have set 1/100th as my primary value, but (to my eye at least) the 1/60th shot was better exposed. My fault for not checking my exif data.
For what it is worth, the "bump" produced by the camera is what produces a loss of sharpness, and that technically cannot be managed by a tripod. On the other hand, I believe it only becomes important at long shtter speeds or with exceptionally close macros of very tiny things.
