in a lot of the macro photos i read about ppl using a reversed lens to get closer. i fidgeted for a while and couldnt figure it out. Could someone please explain how this works to me, and maybe post a few pics of the setup, this would be really helpful to me. :D

Don't know if this is what you are asking about but it sounds like something I used to do years ago with my old film-based camera - the Mamiya-Sekor 100DTL.
I'd remove my 55mm normal lense and physically reverse the lense and hold it with my hand back up against the camera body. I could take macro shots that way. It actually worked pretty good but it was a manual camera with a rod that I could hold in to control the f/stop. There were no electronic components to the lenses.
Optically it should work with your camera's lenses, but the electronics to the lense might screw that up.

There is a connector ring, with reversed threads, that fits on the end of the lense, it holds one reversed in front of another. There were some pictures a while back, but I'm afraid I don't remember the thread.

To do this, the reversed lens should be a relatively wide-aperture lens. The Canon 50mm f/1.0 works well, but it does not even need to be a Canon lens since you will not be mounting it to the camera -- I think Jacko uses an Olympus lens because he got it cheap on Ebay. There are reversing rings available that will hold the lenses together for you -- basically they have two sets of filter threads running in opposite directions and you screw both lenses into it. If the lenses use different filter sizes you would use a step-up ring as well.
You can hold the lens as well, but that is tricky for obvious reasons.

Go to B&H and do a search for "macro coupler".

So, what is the best thing to use for a first lens? I mean the one that is attached correctly to the camera body?
If I use, say a 24 - 70, should I set it at the 24 or the 70?

I use the 100/2.8 Macro with the 50/1.4 reversed. Has the advantage of both having 58mm threads, and there is very little vignetting with this combination.
Oh, and 70. But I don't know if I would hang extra weight off the end of the 24-70, since it's an extending zoom design.

Another question out of curiosity-- what do you do to protect the exposed end of the reversed lens from dust, etc. while shooting?

Be careful.
It helps to use an old manual lens to reverse. I got an old Minolta 50mm lens for $6. Works great, and if you really bust the lens, you're only out $6. |

seeing how close you need to be - i'd be more worried about actually banging the reversed lense into the something than dust. dust is cleanable - scratches are not.
