I just tried taking some shots at my desk and while it focused fast, I wouldn't say it's living up to the hype of 6 multi focal shots per second.

EDIT: It appears that they are using the MEMS acronym, not the branded product. The component itself does not look like the MEMS|Cam branded components either.

Edit 2: Just read more on MEMS and if this phone has MEMS, then the camera software is NOT supporting it. It can take up to a solid second for the camera to make even minute adjustments.
