As most iOS photo enthusiasts know, none of the Apple iOS devices have an optical zoom. Several apps provide a digital zoom, but zooming simply blows up the picture, making the pixels larger. The result, is a pretty crummy-looking larger version of what you'd see with no zoom. A new app, called Video Recorder with 30X zoom, attempts to beat that problem, but not very successfully.
The app is universal, and sells for US$1.99. It works for video or stills, and claims to be the best zoom app around. That may be, but it still falls short of what most photographers will expect.
The app has a clever slider bar across the bottom of the screen. You can slide from 1X to 30X easily, but the picture just does not hold up. Even with a 3X zoom, artifacts were pretty obvious.
