Well, I have solved that problem with a FREE application that you can get from the App Store. Just search for A+ Camera Zoom and install.
The application is easy to use and with just small strokes, you will capture your photos in the distance that you want. I have tried other zooming applications but this one does the job. Photos are automatically saved in the Photos folder unlike other applications that you don't know where it is being saved.
