Paul Boyce finds that the iPhone 4S's camera is inconsistent when it comes to autofocus.



From PC World:

There appears to be an issue with the iPhone 4S video camera that affects my 4S as well as that of two other friends who have the same phone. The auto-focus function on the video camera does not appear to re-focus as it should. I've posted a YouTube video that demonstrates the issue.
