Always wanted to do this, and when i was looking for the relevant coupling rings, i came across this:
//cgi.ebay.com/Reverse-coupling-ring-52mm-58mm-macro-close-up-lens-NEW_W0QQitemZ110023212392QQcmdZViewItem
On the tutorial //www.dpchallenge.com/tutorial.php?TUTORIAL_ID=40, it says to use a coupling ring and a stepup ring, but would this alone do the job?
Also, anyone else done this? comparison to a true macro lens?
thanks

yes that would do the job alone. I assume you need a step up ring if you are going to be combining 58mm with a 72mm. I actually have a 52mm-58mm and it works fine.

yep it will work, as long as you have a lens backwards somehow it seems to work.
I just mount a lens straight onto the body - no need for a coupling ring at all. I lose the ability to meter but once I work out the correct exposure it works fine.

Hello,
I have exactly the same - a 52mm - 62mm step-up ring to combine my Canon 50mm 1.8 to my Tamron 70mm-300mm, and also a 52mm - bayonet fitting to reverse mount the 50mm lens alone. So you only need one ring, but I chose two different ones to give different degrees of close-up.
The first thing you'll find is the INSANELY tiny DOF - you'll need to fix your camera rigidly to a tripod, then I'd suggest moving your subject (rather than your camera) with a cocktail stick or something.
Eg.
//www.dpchallenge.com/image.php?IMAGE_ID=335344
and
//www.dpchallenge.com/image.php?IMAGE_ID=358399 (DOF of about 1mm!)
I've never used a true macro so I can't comment on that - however I'd imagine the DOF is somewhat more workable. But I think the rings are a great cheap workaround.
Have fun in the miniature world!

here are some examples of reversing a 50mm on a tamron 90mm macro :
   
 
on top of the _very_ shallow depth of field, you also get a lot of barrel distortion, as you can see from the knife photo...
it's quite fun, though...

It works great, although it takes some getting used to. I used the technique for this one
