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

And also, not everyone wants to sit in front of a bright light

More like 500, around 1000 if you need a high quality lens
