THE CAMERA THAT COMES WITH THE iPHONE IS TERRIBLE
Many people decry it’s smallish megapixel count (3), but really, as any serious digital photographer will tell you, size doesn’t matter. The most frustrating thing about the image that comes from the iPhone is the noise. Not audible noise, but digital grain. That, and it’s slow response time, and of course, the lack of control: apart from aiming the camera, selecting a focus area and depressing shutter button, the user doesn’t have any control over aperture (fixed at 2.8) focal length (fixed at 5.9mm), shutter speed, or even ISO, which swings from ~70 into the 1000+ range as it wants.
