One of the new features of the4S is a 1080p HD video camera. This new camera sports an f/2.4 lens and improved sensor to capture more light. It also has video stabilization to steady those shaky shots. To see me put this new camera to the test, check out the video below.
This is a very short video taken by my4S.I am very impressed with the video camera. Also, check out the photos separately taken by and iPhone 4S, see how differences between those.
