Free Zoom app
One of the things missing from the iPhone camera was the ability to zoom in and out to make a better composed photograph. It has a simple slide control at the bottom of the screen the makes the camera zoom in or out. It also features a touch focus like the original camera. Once you have zoomed in and composed the photograph touch what is the main point of interest of the iPhone’s screen. The camera will focus where you touch. Be aware that this is a digital zoom not an optical zoom. It uses software to zoom in and therefore there is some loose in picture quality. The picture is a little grainy.
