This webcam is excellent and fully compatible with Rasberry Pi, unlike the C920 that plants after one or two hours. Small flat, the employee is a Tessar lens, an optical system 1915 which certainly displays the Zeiss logo on the box but that was never designed for wide angle. Result, due to its strong field curvature, the image is blurred at the edges when filming a long distance, for example scene (but it does not feel in use of video chat). Note that the problem is identical to the C920.
