What does infinite zoom of lens mean?
In shooting, sometimes it is necessary to shoot distant targets, or it is necessary to shoot details at close range. If you use a traditional lens, you may need to constantly change different lenses to achieve this. Using the lens zoom function, you can freely switch the far and near focal lengths, thus completing various shooting tasks more quickly. This can not only improve work efficiency, but also better maintain the continuity of creative inspiration.
It is precisely because of the infinite zoom of the lens that many film and television works can present more shocking visual effects. Action movies, for example, can present the changes of the scene more vividly by changing the focal length of the lens quickly, so that the audience can better feel the dynamic of the picture. In a word, lens zoom, as an application of shooting technology, plays an irreplaceable role in improving the picture effect and working efficiency.
