Yeah - without even knowing what it was, I'll second what gryphonslair99 said. I've never seen a threaded add-on lens that didn't produce terrible image quality. A lot of photographers don't even like to put filters in front of their expensive lenses - let alone some questionable zooming optics. My advice is to ignore all the tourist camera stores in SF and only go to real camera stores or come to us when you need a lens recommendation. We aren't trying to sell you anything and we aren't offering any miracle cures
