To deliver image-perfect detail and clarity, the Logitech QuickCam Vision Pro webcam combines Logitech's premium autofocus technology with Carl Zeiss optics. The 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. Logitech's autofocus system compensates for changes in image-edge sharpness and refocuses images in less than three seconds. And through its exclusive collaboration with Carl Zeiss, Logitech ensures that the lens meets the world-renowned Zeiss standards for design and manufacturing to achieve superior sharpness in a compact, lightweight design.The 2-megapixel sensor helps the Logitech QuickCam Vision Pro webcam capture video images in high resolution. It is assisted by Logitech's RightLight 2 technology, which enables the webcam to adjust intelligently in dim or harshly backlighted situations.
