well those extension tubes work with any lens or do you have to buy specific ones for your lens brand or type? |

They are mount specific, so you need to get the ones built for the Canon mount. The Kenko tubes are the ones many folks go with.

Here's a picture of our dog that I took with my Canon 60mm macro:

I knew you would have to use the one built for your specific camera mount, I just did not want to screw up a lens or buy something that would not work.
Is a teleconverter lens specific? |

The Canon teleconverters are. Some others may be. The Canon ones, in particular, fit mostly L lenses above 70mm. Canon does have a table of compatibility for theirs.
My tamron 1.4x (non Pro version) on the other hand, fits pretty much all my Canon lenses. What they do and don't work with varies from converter to converter :-P
Edit:
When using the Canon converters, putting a 12mm extension tube betweenthe converter and the lens eliminates the mechanical interference problems, so for instance I can use the Canon 2.0xII converter with the (normally-incompatible) 100/2.8 Macro to achieve >2:1 magnification.

I got my hands on a XT and a Sigma 75-300mm with macro function a week ago. Great lense, and gives you and extensive use range. I know you're probably not looking to purchaise a lense with that much range, but i was extreamly happy! and again, extreamly noise using auto because of the lack of USM ;-) but really, affordable, you should give it a look |

Will using the Kenko tubes allow you to retain autofocus?
what is the advantage of having either a 12mm or 25mm tube? |

Yes, AF will still be possible. Practical? That's another matter. At high magnifications, it's much better to set the focus to set the magnification desired, then move the camera back & forth to focus.
The more tube length you add, the closer you're able to focus and the higher the magnification will be. You can stack two or even all three tubes together; the three tubes give you a lot of possible combinations of different total lengths.

Can you use a tube with a macro lens? would this be an advantage?
I really appreciate your patience and help I always have alot of questions. Ignorance is not bliss to me its just a pain my rear. |

There's a problem with Kenko tubes, for the record.
From: //www.thkphoto.com/products/kenko/slrc-04.html
"3. Canon EF-S lenses will not mount on the KENKO DG Extension Tube Set. These lenses include but not limited to EF-S 10-22, EF-S 17-85, EF-S 18-55, and EF-S 60mm Macro. "
I bought the much cheaper Prooptic tubes and they are fine, and support the EF-S lenses.

Yes. When you need more magnification than 1:1, you can add an extension tube to a macro lens. Works great. Here...
...is a chart showing how magnification is affected using the Canon 100/2.8 Macro lens and various combinations of accessories. As you can see, with a 12mm and 25mm tube, you can get 1.5:1, which ain't too shabby.

I'm probably going to pick up some extension tubes eventually. I'm pretty excited to do some extreme macros when the weather gets nice.
This thread has been really helpful for me. Thanks for all the great info, Kirbic. I really appreciate it.
