A lack of native zoom is a real hindrance with the iPhone camera when shooting video. But fortunately, there are apps that let you add digital zoom. Video Zoom 2 ($0.99) gives you up to 3x digital zoom, including real-time zoom during recording -- without decreasing image stability or frame rate. It offers a choice of four different resolutions for the iPhone 4. You can view videos from within the app, and can shoot any number of videos before coming back to preview or export.
