Macro Lens Focusing: Full Vs. Limit

What does Full and Limit on a macro lens means? It's a 50mm macro lens. Thanks.

Michael H. Cothran   A macro lens has a VERY LONG focusing range from 1:1 out to infinity. Thus, manufacturers give you the choice of utilizing the full focusing range, or limiting this focusing range to either the short half or the long half end.
When you set the lens to "Limit," it will only focus in the half of the range where you were focused before setting it. To get to the other range, reset the lens to "Full," then focus into the other range and reset back to "Limit."
This feature is particularly useful if using auto focus, as otherwise the lens will use up a lot of time and battery power hunting throughout its immense focusing range to find whatever you are focused on.
