When you place a long tube over the camera's lens, you're reducing that angle which is reflected in the picture as a black circle. I'm sorry but I didn't try any telephoto lens converter. A similar principle should apply though. This solution prevents vignetting by allowing a wider angle.

How does this systems prevents vignetting. Am I missing something here? Could you explain? Thanks.

Works just fine. It also depends on the length of the tube. I bought this one on eBay, so there's no guarantee that another tube from eBay will have the exact length. However, it's not so expensive to begin with, it's your decision. I tried it with two filters. Works just fine. It also depends on the length of the tube.
