I used to use 58mm to 58mm male to male Macro coupler

and then a 52mm to 58mm step-up ring.

Totaling about $18

I recently went and purchased a 77mm Macro coupler and step-up ring for my 100-400 lens. So now I have an IS, reversed macro lens
Hope this info helps.

Alright, so when reversing lenses, how do you go about focusing? And can you reverse any lenses, or just particular ones? Sorry bout all the newb questions!

Depending on how far you have zoomed.
at 300mm on the Siggy and at 50mm on the attached you can get close to 4x-5x magnification.
I found that to increase magnification the reversed lens needs to be less than 50mm, to decrease magnification, it needs to be greater than 50mm
So with an attached 28mm lens reversed you'll achieve approx 6x-7x mag and also some funky focusing with an extremely shallow depth of field.

As others using the reverse technique have said make sure all aperture control is done through the camera with the main Sigma lens attached.

As for actual focusing, this gets very tricky and requires a lot of trial and error and patience.
Set the Sigma lens to Manual focus (MF) it doesn't really matter where the lens is focused but set it on Infinity.
Rocking back and forth very slowly whilst looking through the viewfinder you'll see areas come into and go out of focus, learn to perfect this technique.
You'll soon learn that even as you breathe, that it will play major havoc with your focusing, especially on higher magnifications, try and perfect the technique on inanimate objects first to understand where your set-ups strengths and weaknesses are, then the fun really begins when you try and chase bugs with a slight afternoon breeze
good luck.

OK. I just ordered a reverse male/male 52mm coupling ring. I plan on trying this with my 55-250mm and the kit lens (18-55) reversed. And, just to clarify, I change the focus on the 55-250 and leave the reversed lens be, right? Should I set the reversed lens to -infinity?

both lenses you don't mess with the focusing. so set both to infinity and just rock back and forth with your body to achieve focus.

You can focus with the lens reversed, no problem. You'll need to set the aperture you want, then hold down the DOF button while removing the lens (camera on). That aperture will remain set in the lens.

Got any pics of what that setup looks like?

I'll have some pics by tonight, are you wanting pics of the set-up or pics taken with the set-up.
It is just a regular Canon 100-400 with a reversed 50mm Canon FD mounted to the front of the 100-400, the whole rig combined is just shorter than the 100-400 with hood attached.

He'll be able to get close to 3-4X possibly, I used to get close to 5X with my old Sigma 70-300 and Reversed 28mm, you'll get heavy vignetting between 70-135mm.
Definitely need Extra light from flash

Not only that, it's too dark if there is less ambient light. Imagine looking through a lens stopped at f-16. But it pays off. Following few shots are just taken, not great subjects but shows potential of reverse magnification. I used 30D with body reverse ring and mounted old manual Rikkenon 28-70mm lens (that had aperture ring).

Pics of the setup. Sounds like a rather heavy rig for macro work. I have the 100-400 myself and I couldn't imagine trying to hold it steady enough by itself to do macro let alone with an FD lens mounted to the front.

It really isn't too bad, yeah it is heavy but so was the other set-up (Sigma lens) especially with the 580EX slung to the left or right.
At least now I have the 580EX attached to the Tripod ring
FD lens really isn't that heavy.
Here's a pic of the set-up
