Logitech QuickCam Vision Pro webcam is the first Mac-compatible webcam with premium autofocus technology and Carl Zeiss optics from Logitech. The Logitech QuickCam Vision Pro webcam for Mac delivers image-perfect detail and clarity, and exceptional video calling with iChat and Skype. The new Logitech webcam uses a voice coil motor for its autofocus system, instead of a stepper motor. Focusing is fast and fluid – crisp even in extreme close-ups only 10 cm from the camera lens. The QuickCam Vision Pro records sharp video clips in the 720p high-definition (HD) video format (960-by-720 pixels).
