I do it like this:
Take my 50-200, $20 SMC Tak 55/1.8 , $5 Reversing ring and get very close:
But if i did not had the 55/1.8 laying around, i'd probably get something like those Raynox snap on things, because the filter threads are very inconvenient. That piece of heavy Tak glass and metal hanging from the noose of plastic 50-200 feels unsafe as well (and causes zoom creep when pointed lower than ~45 degrees down). I use 50-200 aperture for DOF control (Stopping 55/1.8 just causes vignetting without much effect), and focus with all three 50-200 focus and zoom (yes it can move the area in focus at those distances and is easier to grip) rings as well as 55/1.8 zoom ring.
Macro rings again require additional mounting and unmounting without that much quality gain over snap on, than a special purpose macro lens.
