Why do commercial photography mostly use zoom lenses?

Focus on lighting, lighting is more important than the lens.

Then many shots need to change the composition frequently, which is convenient for zooming, and it is not practical to carry a bunch of shots on the location. The model will laugh when changing the lens. It is ok for you to go out and play by yourself, but will you still miss the problem of bringing two or three lights and power?

But these are all portraits, animals and other creatures are like this. Zooming is useless when shooting products and buildings. The basic products are all macro heads, and the buildings are all moving shaft heads (provided that they can't reach medium and large, but medium and large are more common).
