Camera
Well, as an avid camera user there are both good things and bad things about the iPhone5 camera:
1 - there is no way to shut off the image stabilization that I can find. In a perfect world I'd shut it off for still shots and have it on for movies.
2 - the autofocus is noticeably slower under certain lighting conditions than that of the iphone4 I used for multiple years for thousands and thousands of photos. Even in seemingly bright light. Yes, it's dealing with 3x the pixels but the processor is much faster so it should do okay theoretically.
3 - the facial recognition seems to turn on randomly for things that aren't faces. I actually wish I could shut the facial recognition off altogether because sometimes I'm not photographing people.
Yesterday I was in my car at a stoplight and saw two very high flying jets that were very close to one another and I started taking a movie of them - the first 4-5 seconds were perfect but the autofocus then wanted to focus on a piece of dirt on my windshield (which it showed up as facial recognition!) and wouldn't refocus on the planes despite tapping on the planes themselves on the screen to reorient the focus back to this stupid piece of dirt!
4 - it does do better in low lighting than the previous iphones for still shots but there's a certain point where if you are filming, say, a sunset type scene in movie mode with other things like cars and birds moving about the phone decides to randomly modulate the light levels and I've caught this on video - not only does it decide to randomly autofocus and change the light levels but if you tap on the item you want it to focus on it snaps to that object briefly then the autofocus starts wandering again. The more towards evening the light levels are, the more this behavior occurs.
Obviously the camera has a lot of potential - I've taken some pictures my iPhone4 could NOT have taken, some with astounding quality but it's almost like I need to learn a new photographic technique to get the most out of this particular camera.
I wonder if there's a "iphone camera forum" somewhere?
