What kind of lens is used to shoot the auto show?

I have been to every auto show in Shanghai, unless you have a special relationship with the official or media reception two days ago. If the ordinary audience buys tickets, there is only one sentence when they arrive at the scene. Only when they see the head can they not see where the car is? Especially imported brand-name cars, it is difficult to enter.

Therefore, if it is useless to take a telephoto lens of a car, it is ok to take a close-up of the car model. But the car models are all beside the car, so the only way is to try to squeeze in front of them and use standard zoom lenses such as 14-42, 18-55 and 24-70 of the full-frame machine.
