Nice way to visualize lens choice – LensTutorial Review

This is a nice app to visualize the way that focal length relates to distance to subject, depth of field and width of scene. If the focal lengths could be set to snap to the user's preferences (example: 70mm, 85mm, etc.) I would give this app a perfect score. Well done, nice interactive and useful photographic aid.
