Scott:
I work for a company that has been working on designing tiny piezoelectric devices for tiny autofocus mechanisms (mainly for cell phones). While most people don't even know this market exists, it is VERY competitive and there have been alot of companies that have been working on this for years because they foresaw that this would eventually become a necessity in cell phone devices.
So, the autofocus technology on lenses like this is not necessarily new. However, it is very cost competitive, so I would be concerned about the quality of the autofocus mechanism. But, the quality of the images is legit I"m sure.
