Just received my Lumina. Gotta say, I was prepared to be underwhelmed ... webcams just do that to me. They usually suck. I almost pulled the trigger on a $2000 setup with a DSLR, but this was my last chance. Yet this camera just nails it. Great video quality, looks like a DSLR out of the box with very little config, and the audio quality is top notch for a camera.
The blur/bokeh is surprisingly well executed, with the image easily passing for DSLR on Zoom.
Also, other USB cameras (or Reincubate Camo which uses iPhones as the camera) often don't work in Photo Booth, FaceTime, etc. The Lumina does.
Just get it.
