reverse mounting for macros? or native 60mm

just wondering if any NX users have tried this, and if they could help me out

where would you buy reverse mounts?

how exactly does the lens end up connecting to the camera body? how do you MF if it's reverse mounted, i.e. the electrical contacts aren't there to be able to focus by wire

Also, how close will the native NX 60mm get you? can you take close up "portraits" of bugs?
