Why do commercial photography use telephoto when the indoor studio is very close?

The coverage area of the flash is limited, the light source at the edge will be reduced, and the light ratio will be different. The angle of the flash and the problem of random reflection may be projected onto the lens, causing unnecessary glare. This happens especially when the lights in the small studio don't turn on. The telephoto lens has a small field of view, which can avoid the above problems.
