I can't keep up with the focus when shooting, either too much or too little. The skill of seeking attention!

Some funny cameras upstairs are still in follow focus?

The problem of following the focus is first of all a question of proficiency. It is normal for the landlord to start following focus. It is necessary to practice more. I usually feel and get used to the lens focusing. Practicing more is a process. Remember, you must predict the direction of the movement and have a degree in mind when you exercise.

Follow-up focusing generally means that the moving picture in the camera's field of view changes its focal length with the motion of the subject.

In photography, it can only be regarded as a quick focus snapshot.

Answer the landlord in detail again. Are you talking about making a film and television drama? Generally speaking, someone can help to become a member of follow focus. If you are like a TV camera, you can only judge for yourself. Although there is a similar formula from near to far, generally speaking, it can only be decided by one's own experience and proficiency, and by one's own eyes and feelings.
