Manual Lens Adapter with Helicoid Macro Tube for M42 42mm Screw-Mount Lens to M39 39mm Screw-Mount Camera Body.

This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.
It allow you to take close up/macro image more easier when full extended. It can focus infinity when closed of course.
