A:AnswerThis has a decent wide angle lens - it picks up a good view of my home office (in fact I'd like it to zoom in and be less wide!). The box says it has a 78 deg field of view - more than enough for me.
It does display in 16x9 (1080P) - so in that sense it is HD (wide screen)
A:AnswerNot this model, although there are C920 HD webcams with Carl Zeiss optics. It have "Carl Zeiss" written on the lens itself. https://www.bestbuy.ca/en-ca/product/logitech-logitech-hd-pro-webcam-c920-960-000764/10275905
A:AnswerHello Microphone! The c920s Pro Webcam with Privacy Shutter does feature two microphones, one on either side of the camera, to help capture more realistic sound from a broader range of angles. - Mathieu from Logitech
