To add onto this, 12 megapixels is just not going to look good with a major crop/zoom--at all. Optical zoom is the only way to zoom without losing quality--assuming that you are running at the same aperture, ISO, and shutter speed (which is not the case for iPhone cameras). It's not a high def camera and the megapixels of the sensor severely limits the useful cropping of images if pixelation is a concern. The size of the sensor also greatly limits the low light capability. There would be less grain with more light (due to lower ISO), but if you want pictures that you can crop and zoom on without losing much in terms of quality, you need a better camera.
