Functions and precautions of telephoto lens

When playing outside, I always envy those who hold SLR cameras and leave the beautiful scenery of the motherland in the camera. For photography, it is actually an art, and there is great knowledge only in the choice of SLR camera lens. For example, do you know which of the related functions of telephoto lens is more suitable for SLR cameras?

A good telephoto lens is more important for people who like photography and have played with SLR cameras. The choice of telephoto lens may be difficult for beginners. For beginners of photography, first of all, we should understand telephoto lens.

The role of telephoto lens:

The main function of telephoto lens is to take distant scenes into the lens. A telephoto lens is different from a standard lens. The focal length of telephoto arrow is much longer, the viewing angle is much smaller, and the image displayed on the negative is much larger. Therefore, at the same distance, the telephoto lens can shoot a larger image than the standard lens. For telephoto lenses, they are better at shooting distant images and shooting details. For example, animals running in the distance on the African savannah need telephoto lenses to shoot.

Matters needing attention when using telephoto lens:

For people who use telephoto lenses to shoot scenes, there are several points to pay attention to, which can help you use telephoto lenses better and take more perfect photos.

Note 1: When using telephoto lens, be sure to be steady. Because the telephoto lens is not only long, but also heavy, a little jitter will make the photos unclear. For telephoto lenses, most of them are not hand-held, but tripod, which can ensure high-quality scenes.

Note 2: For telephoto lenses, weather is also a major factor. When the weather is clear, the sun is shining, the colors are full and the contrast is great. As a subject, the photos taken are very good.

Note 3: A feature of telephoto lens is that it is easy to produce a sense of spatial perspective compression. We often want to fit all the scenes into one lens, but the standard lens can't achieve this effect, so we can use a telephoto lens. By using the sense of space compression of telephoto lens, distant scenes can be taken together compactly, and a compact picture effect can be taken.

For beginners in photography, it is advisable to slow down, learn to use standard lenses first, and then master telephoto lenses skillfully. For photographers who have mastered telephoto lenses, they can perfectly shoot the scenes they want, not only the distant view, but also the capture of details.
