Short focal lengths yield a wider field of view, capturing more of the scene in a single frame. A 13mm lens is at the lower end of the focal length range, so it provides a broad perspective rather than magnifying distant subjects. Telephoto lenses have long focal lengths and narrow the view, while normal lenses sit in the middle and fisheye involves extreme distortion. On common SUAS cameras, 13mm is best described as wide-angle.
