I found this article while searching the tech section of Google news.
It talks about the droids camera being on some odd cycle..
Motorola DROID’s Autofocus Woes Change with the Moons
There’s a rounding-error bug in the camera driver’s autofocus routine (which uses a timestamp) that causes autofocus to behave poorly on a 24.5-day cycle. That is, it’ll work for 24.5 days, then have poor performance for 24.5 days, then work again.The 17th is the start of a new “works correctly” cycle, so the devices will be fine for a while. A permanent fix is in the works.
