The WRS-1010 adds 10mm of extension to the default focussing range (for slight macro)
The WRS-1017 adds 17mm of extension to the default focussing range (for more macro)
The WRS-1048 adds 48mm of extension to the default focussing range (for extreme macro)
These adapters are stackable, so any extension can be achieved.
