Do beginners in photography buy fixed focus or zoom lenses?
First of all, let's distinguish between a zoom lens and a fixed focus lens.
A zoom lens can change the focal length within a certain range to get different viewing angles, images of different sizes and camera lenses of different depth of field, such as the Canon 24-105mm fhand 4L lens. A fixed-focus lens is a lens with only one fixed focal length, such as the Canon 50mm fhand 1.8 lens. In terms of convenience, the zoom lens is better than the fixed-focus lens, but in terms of picture quality, the production process of the fixed-focus lens is relatively simple, so that it can obtain better picture quality than the zoom lens.

So do beginners in photography buy fixed-focus or zoom lenses? Mr. Jinhua advises beginners to buy a zoom lens for the first lens. Canon's screenshot set of 18-55mm or 18-135mm lenses is fine. Why not recommend buying fixed-focus lenses. Because photography beginners are not familiar with the composition, which focal section can shoot what kind of effect is not clear, can only be familiar with more shooting and groping. At this time, if you buy a fixed-focus lens directly, you can only shoot a scene from a certain angle of view because of the limited focal length, so it is impossible to train the composition from multiple perspectives.
Many businesses often offer a multi-mirror package, such as a fuselage with 18-55mm lens and 55-250mm lens. In this regard, teacher Jinhua does not recommend that beginners buy double lenses directly. If you really need to use more than 135mm focal length, such as shooting birds, it is recommended that you buy an 18-200mm single lens. In theory, 18-55mm lenses and 55-250mm lenses can form 18-250mm focal length lenses, but in practice, only one lens can be installed on the same fuselage, so you can't quickly use 250mm focal length to shoot distant birds, and then quickly switch to 18mm focal length to shoot a large scene close to your feet.

Teacher Jinhua suggests that beginners in photography can shoot more of the things they are interested in at the beginning and do not have to stick to fixed subjects. Take the 18-135mm lens as an example, you can use 18mm to shoot sea scenery and city scenery, 35mm to shoot humanities, 85mm to take portraits, and above 135mm focal length to take pictures of birds and flowers. During the specific shooting practice, you can set the lens focal length to the above specific value, then fix it with adhesive tape, and practice the focal length one by one according to the cycle.
For example, this month fixed to the 18mm focal length for practice shooting scenery, next month fixed to the 35mm focal length shooting humanities. At the beginning, after practicing all the focal lengths, scholars counted which focal lengths of their photos were used most through the Lightroom software. In this way, you can know which fixed focus lens is suitable for you to buy or upgrade.

To sum up, beginners in photography are advised to buy an entry-level machine zoom lens. After scholars have practiced taking a certain number of photos (say 10,000), they can consider upgrading the zoom lens or buying a suitable fixed-focus lens.
