I doubt you'll find the specifics about the camera outside of internal Apple documentation.

Yeah...I gotta agree. Sometimes it tough just to get simple megapixel data on earlier built-in web-cam's. Even on newer Apple built-in webcam's there's not a lot of info.

For example...look at the "tech. specs" in the link below for the built-in camera on a new retina MacBook Pro. All you get is "720p FaceTime HD camera":lol
