I have posted my review of the new Microsoft LifeCam Studio, released in September. Here is an excerpt:

The Microsoft LifeCam Studio builds up the design from the Microsoft LifeCam Cinema, released in 2009. There are several improvements though. The most noticeable difference is the high-end, brushed aluminum design - that really sets it apart even from its main competitor, the Logitech HD Pro Webcam C910. The Studio is bigger than the Cinema, it's about 4.5 inches tall and 1.5 inches wide. The USB cord is of decent length, can can attach to a desktop underneath the desk. You can also rotate the camera 360 degrees, which is nice. The adjustable clip is also sufficient to attach to any LCD monitor. There is a blue-lit call (in use) button on the top, next to the microphone, in addition there is a nice lens cap that you can use to cover the screen. For those with tripods, there is a tripod thread at the bottom. Overall, I think this is a very attractive webcam. It fits nicely into a high end desktop - and I feel can be used for consumers but also in any professional office setting. The camera frame rate is up to 30 frames per second, and the max video resolution is 1920 x 1080 (both adjustable), while the max still image resolution is 2304 x 1728 (4 Megapixel).
