Of course, the point was more that regardless of price the following holds in poor light: webcam < phone < point and shoot cam < dslr. Why are there no webcams with actual optical zoom lenses and decent sensor sizes? Why doesn't Canon or Nikon have a go, or Sony? The market (at least now) is a lot bigger than that for camera's. Even in the longer run, I bet a lot of people are willing to spend a bit extra to have the best looking image in the meeting. Everybody my wife videoconferences with immediately notices here camera is way better than theirs
