Are you shooting a video and want a good illustration of how different camera and focal length combinations will render a scene? Check out this cool Field of View Comparator Tool on the Canon Digital Learning Center.
All you need to do is choose your focal length and the two cameras you want to compare. The tool gives you a visual representation showing the difference between the two setups – sample angles of view, crop factors and what focal lengths you need in order to match one scene to the other are all readily displayed.
