What is best for all kinds of lenses?

The following is an excerpt from my blog post: Introduction to SLR: Choice of Lens.

The original text is too long and illustrated. I am interested in clicking the link I gave.

I hope it helps your problem.

1. Focal length and purpose of lens

Please refer to the previous section for necessary parameters such as lens parameters and focal length.

What I want to talk about here is the purpose of each cola joke.

Non-full width <16mm, full width

Non-Quan Huafu 16-50mm, Quan Huafu 24-70mm, this focal length is called standard focal length, or golden focal length, which is our most commonly used focal length. The standard lens set you bought is basically the lens with this focal length.

There are several special focal lengths that we need to remember.

Non-full-width 24mm, full-width 35mm, this focal length is called humanistic focal length, which is suitable for taking pictures of humanities, that is, taking pictures in the street, commonly known as sweeping the street.

Non-full width 35mm, full width 50mm. This focal length is called the standard focal length, which is the closest to the focal length of the scene seen by the human eye and is very important.

Non-full-width 50- 135mm, full-width 70-200mm, this focal segment is called middle telescopic focal segment, which has entered the telescopic category, but this definition is not very standardized, so there is no need to delve into it.

In addition, there are several important focal lengths that we should remember.

Non-full-width 50mm, full-width 85mm, this focal length is called the golden focal length of portrait, which is necessary for portrait photography.

Non-full width 60mm, full width 100mm, macro necessary focal length, commonly known as Budweiser.

Non-full-width 85mm, full-width 135mm, this focal length is called the golden focal length of portrait photography, and it is also a very important focal length.

The partial width is > 135mm, and the full width is > 200mm. This focal length is the telephoto focal length and the coverage of telephoto lens. It is best to prepare one for sports, flowers, animals and other photography.

There are also some important focal lengths. Because the focal length is too long, it seems that things that are not full-width are not mentioned. Here we only say the whole picture.

Full width 180mm. I don't know why, this focal length is used to shoot macro.

Full width 200mm, 300mm, 400mm, 500mm, 600mm, etc. , mainly used in sports photography, news photography, etc. Hehe, it is too expensive to buy a word. I don't want to discuss this.
