Conversion Lens for Panasonic

I’ve recently bought Panasonic PV-GS150 camcorder and while searching Amazon I’ve stumbled upon Kenko 2x Telephoto Conversion Lens. I realize that having this lens I’d get more into my picture, but does it help the quality of picture as well? Its sharpness, more light to come through? What else would it help with? Thank you.

It will degrade the quality – you can’t improve it by adding a lens.
