I have no idea how you macro guys do your magic, but here are a couple of my best attempts using my D700 with 24-70 f/2.8 and 36mm Kenko tube. I used off camera flash (hand-held). Honestly, I'll admit that I don't know what I'm doing an would love any advice you may have on how to improve. Exif is intact.
These little guys sure don't stay put to pose
