Hello everyone,there is a small experience to calculate the relationship between the lens and distance as well as span.
4.8/25mm * far = width, for example 4.8 / 25mm x 50 m =9.6 meters, then 25 mm lens, at a distance of 50 meters of the position, the left and right sides of the actual width is 9.6 meters.
Hope this formula for all of you to help.
