It seems a little crazy that a cell phone video should be in any way comparable to the Canon 5D MKII. But the fact that the comparison looks so good is startling and makes you think about what's happening with technology and miniaturization.
The comments from the guys that did the comparison are a good summary that puts the comparison in perspective:
This test is really only to show that the 4S is coming close to the 5D but in NO WAY is it better. The iPhone is a great 1080p pocket camera and shows us where technology is heading. Give it two three years and we should see some interesting micro high performance cameras.
The iPhone falls apart in these areas:
- Compression / codec (it's very noisy even in daylight)
- Tiny tiny tiny tiny sensor
- Lens (f2.4 is great for a cell phone though)
- Shutter (no control / stuck on auto)
- Framerate (stuck at 30p)
- No picture styles (contrast and sharpening is heavy)
The only points I give to the 4S are the resolution and portability.
Brace yourself for a flood of high quality cat and laughing baby videos because as of last weekend, 4 million people now have this capability in their pocket and unlike the Canon 5DMKII the iPhone uploads video directly to YouTube.
Update 10/25/2011: There was more interest in this subject than I anticipated. My original intent in posting this was mostly amazement at the rapid evolution in technology. I just ran across a post that Lisa Bettany did illustrating how still image quality of the iPhone has evolved and how it compares to the S95 and 5D.
