If you want to craft the perfect shot while shooting with the default iOS camera, you can tap-hold anywhere to lock exposure and focus. The square focus reticle will refresh twice over the area you hold on, as if it skipped a beat or you’re experiencing deja vü. A label of “AE/AF Lock” will also appear at the bottom of the camera area whether you’re shooting in portrait or landscape.

I’m not sure when this showed up, but I suspect it was around iOS 4. Anyone know for sure?
