When do you need to push and pull the lens instead of the track to make a movie?

Many times, the push-pull lens will be used in shooting, but now generally speaking, the director uses the track to push and pull more, and the lens pushes and pulls less. As for which director in China likes to use push-pull lens, it is not necessarily so. Push-pull shots are generally used when the plot needs them, unlike long shots, which are rarely used because they like them. Here are some examples of using push-pull lenses:

1. Push shot: This kind of shot shows the scene from big to small, so when encountering a dialogue screen, a person has a subtle action expression, and the shot is pushed from the middle shot or close shot to the close-up, which is the most common usage of push shot; Another situation is to enter the scene, which is also very common. It refers to advancing to a close-up or close-up detail in a large-format landscape such as a large field of vision or a distant view, so as to enter the narrative. In addition to the above two points, there are some cases where the push lens is used, so I won't give many examples.

2. Pull the lens: This lens shows the scene from small to large, and the most commonly used is the use of transition and rendering emotions. Generally speaking, when an emotion reaches the extreme, the picture will be quickly or slowly reduced from close range to large field of vision to continue this emotion or as a transition. I remember this application in the movie If Love.
