Smart phones may take "good pictures" but the zoom on them is absolute shite. Just seeing with your eyes is about 1.75x the zoom of a typical smartphone. They have digital zooms, but no optical zoom, meaning the picture just gets more pixelated as you zoom instead of remaining clear.

You can even do a quick experiment to prove this, just take a picture on your phone of an object. Have the camera at the same distance as your eye, and compare.
