Zoom lens, as its name implies, is a lens that can change the focal length. It can change the focal length within a certain range, thus obtaining different field of view angles. You can also take pictures of different sizes and different scenery ranges. At the same time, it is also a kind of lens that most photography lovers like to use. It can cover different focal length ranges, such as the common 17-85 mm, 24-70 mm, 70-200 mm, etc. However, what are its advantages over fixed focus lens? What are the shortcomings?

Let's talk about its advantages first. First of all, shooting is more convenient. A zoom lens covers the focal range of several fixed focus lenses. The focal length can be changed anytime and anywhere without changing the lens. We want to photograph both distant scenery and nearby objects. If there is no zoom lens, we need to change lenses with different focal lengths back and forth. This will be a waste of time and affect the mood. Secondly, it is more convenient to carry. If there is no zoom lens, we need to prepare a pile of lens equipment. But with it, we only need to bring this lens to meet the needs. It can greatly reduce the burden of our travel.

However, zoom lens also has its shortcomings. The first is its large size. Because of the variable focus, the size of the lens barrel will also change with the focal length. Secondly, compared with the fixed focus lens, the imaging is not so clear. Moreover, the imaging quality of the large focal segment span is not as good as that of the short focal segment. Finally, in terms of price, it will be slightly higher than other lenses.

At present, the general brand zoom lens can completely meet the general needs. The problem can be solved without too much investment. We can make choices according to our own needs. Here I also want to share with you a skill for taking photos with special zoom effect. When shooting an object, we can manually rotate and zoom while pressing the shutter. Photos in this state will have a special effect. Just like the dynamic line in cartoons, it is very special.

This article does not explain the advantages and disadvantages of zoom lens in great detail, but only gives a general concept. We also need to study hard, learn from each other and continuously improve our photography skills. Besides, you can also take some pictures yourself and ask a professional photographer to discuss them. We can make good use of the camera and lens in our hands and make more attempts of different types to maximize the use of single lens function.

I hope the above sharing can give you a better understanding of zoom lens.
