better than Pro9000 and therefore a worthwhile upgrade!

As predecessor I had the Logitech Pro 9000, an already excellent webcam.
In direct comparison, I felt the color display in the C910 again significantly more natural (RightLight 2 technology) and sharper (because HD) and even dealing with different lighting situations has been perfected!
Autofocus has worked very well in the Pro9000 and has not changed significantly (was not necessary).

The microphone is now in stereo and has so far experienced a minor upgrade, the holder is, thanks to the rubberized surfaces improved slightly, although (as with the Pro9000) in the state slightly wobbly. Excellent build quality have in common both cams. The software is mature and helpful.

CONCLUSION: Thanks to significantly improved color reproduction, a much higher resolution (HD) and small improvements in microphone and support a worthwhile upgrade!
