Microsoft Lifecam Cinema Vs - Logitech Webcam Pro 9000 HD Webcam Comparison

Microsoft LifeCam Cinema

Microsoft LifeCam there Microsoft makes. My first was the LifeCam NX-6000 and I've been upgrading ever since.

I have been using a VX-7000 for the last year and it's a fine webcam. Best I've used, really, until now. I just picked up a LifeCam Cinema HD on Interwebs for ~US$60.
First, a quick disclaimer. While I work for Microsoft, I don't know anyone in this group and in this instance, I'm just a dude with a credit card and a camera. Any speculation here is mine and any mistakes are mine.
Ok, this is a really tiny camera. I think it was the barrel-shape of the glass lens mounted on the base but I pictured this thing as huge. It's not. It's petite. It feels nice as well. It feels well engineered, not cheap. It also has a nice little feat of engineering on the USB cable - a cable tie that actually works! Miracle of miracles.

Here it is mounted next to my existing LifeCam VX-7000 for size reference:
