My evolution from M & A, setting my ISO, lighting, etc. has evolved to P and S if I need to control the motion, auto ISO, one last thing to deal with when moving quickly from a dark church out into the bright sun, and back-button autofocus to let the camera do the work, but allow me to choose the focus.
At one time and even now, it was about the quality of the pixel. But with the cameras and lenses today having great image quality at almost every setting, it's about the picture. Photography should be about the picture and not the pixel. If an iPhone is the best tool, it can be a marvelous tool to get the best photo and with good craft along with good vision, there are few limits in creating a great photograph with this tool.
