How Does the iPhone 4S Video Quality Compare to the Canon 5D Mark II?

No, you're not going to use the iPhone instead of a dedicated video camera, but along with the glut of new Android phones, cameraphone video is leaps and bounds better than it was just a year ago. You can also download the 1080p source file on Vimeo (right-hand side).
UPDATE: Check out this short film shot on the iPhone 4S. Yes, if you get really close to objects, you can get a shallow depth-of-field look even with a sensor size this small.
As a sidenote, a recent commenter accused me of covering Apple products too much on this site, but my Google Analytics data shows that a whopping 63% of visitors here are on a Mac or iOS device (54% of which is a Mac proper, compared to 13% Mac marketshare in the U.S.). Given No Film School readers are four times more likely to use a Mac than the national average, I think it's safe to say I'm not pushing a personal agenda but rather trying to serve my audience. So, Apple users, here is another video comparing the iPhone 4S's video quality to that of the iPhone 4:

And not to make this post too Apple-specific, here's a shootout video from Engadget comparing the iPhone 4S's video to several other current cameraphones:
