Are you asking about a 1:1 macro lens?

A 1:1 macro lens projects a full size image on the sensor. That means you need a 6 foot sensor to shoot a 6 foot subject.

Not really in the market for one just curious what exactly it does. I think I understand now. Thanks for clearing it up.

it's used to convert 0.26x of canon 50mm 2.8 macro len to 1.0x, that would give you 1:1 magnification for more define macro works. Just to clear thang up and correct me if i am wrong, it's only useable on 50mm 2.8 macro lens ONLY. Many use extension tube from kenko with great result, unless you already have the canon 50mm macro, i don't see the need of the convertor. Hope that helps

Even more clear now. Thanks! I just saw these a few times and was curious what they were used for. It would be just another item to confuse me for now, got enough to learn
