setting field of view of camera in iphone
===

I am using the same settings of capture session as that of Apple's AVCam demo for my application and using the AVCaptureVideoPreviewLayer for live video streaming. I can easily see that the frames in my Application and that of AV cam is little zoomed than the iPhone camera application. I am working in iPhone 4S and 4. How do I make the field of view (zoom level or the area of objects covered in the screen)of my application (or AV Cam) same as that of the native camera application of iPhone?
I use AVLayerVideoGravityResizeAspectFill for the gravity of the AVCaptureVideoPreviewLayer.
