Stop zooming when I film I want to film myself with my iphone, when I'm drawing. The iphone is not moving, and are about 30 cm ≈ 11" above my desk. My paper is on my desk, I sometimes change paper. But when I do so, or even when my hands are moving, the camera "zooms in" on my hands, and then the drawing gets blurry for a second. That's not nice to watch. So, is there a way (or an app or jailbreak) to disable this?
By just holding my finger on the screen, it applies AE/AF lock.
