1. I've read that the camera does not focus or work well. Is this true or are the reviewers using the camera improperly? 2. Can you set focus distance from macro to infinity? 3. Can you zoom with the camera? 4. Can you control aperature? 5. Will any of these functions be available as apps? 6. Can you compare the Droid camera to the Iphone 3gs? Your comments re the camera.
