Query: not good enough

The teleconverter is not sharp enough, especially for a high-def camcorder. I made a test: took the same shot with the converter and without; I blew the second one up 4x in Photoshop. There is not an appreciable difference. Therefore it is not worth it. I would not buy it again. The reason I did not return it is my lazyness.
