35mm or 50mm? Talk in detail about the difference in the use of conventional focal length lenses

   Compared to the camera body, the lens actually occupies a more important position in our creation. The focal length of the lens is obviously the most important determinant of the lens. After all, it determines the viewing range and perspective relationship of the picture. Judging from the various articles about the lens on the Internet, the focal length of the lens is often divided into super wide-angle, standard zoom and telephoto. In fact, in the standard zoom range, that is, between 24mm and 135mm in the full frame, almost every classic focal length has its own distinct characteristics, which gives us a very diverse lens language. In addition to the classic question of which 35mm or 50mm lens should I choose, this article will also answer the question of whether a standard zoom lens should buy 24-70mm F2.8 or 24-105mm F4.


  The old and new standard wide-angle dispute, 24mm, 28mm

   For many long periods of time, 28mm has been considered the “standard wide angle”. In recent years, with the introduction of more and more high-quality and high-spec 24mm F1.4 lenses, while 28mm has few new high-spec professional lenses, 24mm has gradually surpassed 28mm to become a new “standard wide-angle” trend.

  From the perspective of actual use, the 24mm lens should be said to have the impact of an ultra-wide-angle lens and the possibility of restraint like the 28mm. That is, when used properly, Can move freely between with and without wide-angle perspective.

   In contrast, 28mm is a focal length that has no super wide-angle perspective, has less impact, and is more flat, so it is more common in various documentary During photography. The classic Ricoh GR has been a 28mm focal length for so many years, and Leica Q is also a 28mm focal length, and even most of our mobile phone main cameras are generally at this focal length. In short, 24mm is more radical and 28mm is more restrained.

The battle of    humanities lens, 35mm or 50mm

   Compared with 24mm or 28mm, the choice of 35mm and 50mm is even more diverse. Just like Pepsi or Coca-Cola, KFC or McDonald’s, sweet bean curd or salted bean curd, it is difficult to come up with a result.

   Generally speaking, 35 mm is wider, the blurring ability is weaker, and the ability to express the environment is stronger. When shooting humanities, portraits and other subjects, it is more focused on the expression of the environment. And because the focal length is between the wide-angle and the header, it also has the characteristics of both. The so-called “step back wide-angle, further header” refers to 35mm. If you only bring one lens, it will be more suitable s Choice.

   Relatively speaking, the viewing angle of 50mm is more concentrated, the blur ability is stronger than that of 35mm, and the optical structure is mature. Generally, inexpensive headers can have very good image quality. But relatively speaking, if you want to use 50mm to express the environment or sense of space, it is not so easy compared to 35mm, so it is more suitable for use with a 28mm or 24mm lens.

   These two lenses are both classic focal lengths for humanistic shooting. The more convenient one is also different from person to person, but it is not without certain rules: For example, if you want to take portrait photography into consideration, then 50mm will definitely be a better choice; But if photographers prefer to shoot small objects, then the 35mm lens with stronger close-up capability is usually a better choice; in addition, the 50mm lens can maintain a greater distance from the subject when shooting humanistic subjects. This is for the beginning Photographers who shoot humanistic subjects are also factors that cannot be ignored.

  Portrait focal length selection 85-105-135


  Canon RF85mm F1.2 L USM

  85mm, 105mm, 135mm lenses will be considered by us as portrait lenses in the usual sense. They all have a strong ability to blur, and the picture quality is usually good. The main difference is actually more in perspective. We know that the longer the focal length, the less obvious the perspective of the near and far, and the model’s face will be flatter when shooting portraits. In other words, a girl with a small face is likely to be “squeezed” into a fat face by the telephoto lens. Therefore, among the 85mm, 105mm, and 135mm lenses, the requirements for models are increasing. Therefore, for photographers who are just starting to shoot portraits, I would recommend 85mm or 50mm lenses

   By the way, it’s the question of choosing 24-70mm or 24-105mm. Usually we I think 105mm should be much longer than 70mm. The actual feeling is: the 105mm lens is slightly cropped, and the equivalent 150mm has little effect on the image quality. It may occasionally “replace” the role of the 200mm lens; and the 70mm end of the 24-70mm lens is difficult anyway. Cut out the effect of 200mm. Therefore, we recommend that if you are more focused on indoor shooting, then there is no doubt that a larger aperture 24-70mm F2.8 lens is better; but if it is more travel and outdoor shooting, a 24-70mm F2.8 lens with a wider focal length -105mm F4 lens will be a more versatile choice.

  Lens language has its own merits, flexible use is the key

   Above, I introduced the author’s knowledge and understanding of 24mm to 135mm lenses. In fact, it is not difficult to see that from wide-angle to medium-focus, it is the most abundant range of visual language. For those who are new to photography, you may wish to try more to form your own understanding of focal length and perspective. In the future, the key is to be able to choose flexibly according to the subject matter and the demands you want to express.
