Yes the 60 mm micro has the CRC system
Close-Range Correction system
"The Close-Range Correction (CRC) system is one of Nikon's most important focusing innovations, for it provides superior picture quality at close focusing distances and increases the focusing range. With CRC, the lens elements are configured in a "floating element" design wherein each lens group moves independently to achieve focusing. This ensures superior lens performance even when shooting at close distances."
Also I have a LED light ring and it works great, mine can be used as a light or flash. I noticed the flash was a bit slow so if your trying to use it to freeze, then a speed light seems to give me better performance.
Thanks for the info @digitalis
