quality high-end webcam
if you search for the top is that you need
I too had a logitech 9000, the top couple of years ago, well that's even better 920
AF 920 that is even more reactive
the quality of pictures taken is above the 9000 although it is not the level of a DSLR and compact
and above all the shot is immediate, on 9000 I had a several seconds latency has shooting
the video game is also very good, there's no better now
you can put it on a tripod thanks to the screw below
In conclusion if you hesitate between 9000 and the 920 still sold, given the price difference, take the 920
