Microsoft has introduced what it calls the first true HD consumer web camera for PCs, with its LifeCam Cinema. Capable of taking 720p resolution video at 30 frames per second, the webcam sports a glass lens, autofocus, 4x digital zoom and an integrated noise-canceling microphone. The body of the camera is aluminum, while its stand can grip both desktops and notebooks. A Windows Live call button will fire up the cam for use with Windows Live Messenger, Windows Live Movie Maker or Windows Live Photo Gallery.

The camera interfaces via USB 2.0, and will officially be compatible with Windows 7 in addition to Vista and XP. The LifeCam Cinema is expected to become available on September 9th, priced at about $80.
