How to choose a lens for portrait photography?

When shooting portraits, the main differences among the three lenses (35mm, 50mm, 85mm) are: the relationship between perspective and perspective deformation, and the difference in blur effect of different focal lengths.

35mm lens has always been famous for its outstanding humanistic perspective and atmosphere. Advantages of 35mm lens: When shooting half-length and full-length, it can show the environment around the subject, and the field of vision can accommodate scenes over 50mm and 85mm, so that the background can participate in composition as much as possible, set off the subject, set off the subject, echo the subject model or form a balance of composition. Disadvantages of 35mm lens: There are many scene elements, which are easy to shoot randomly and require high composition and framing.

The viewing angle and magnification of the 50mm standard lens are close to those of the human eye, and the sense of compression and visual field are similar to those of the human eye, so a very comfortable viewing angle can be obtained.

Advantages of 50mm lens: Compared with 35mm, 50mm lens has smaller perspective deformation, is more suitable for close-range portrait photography, can shape a very three-dimensional face, is suitable for middle-distance shooting, and can fully interact with the environment to a certain extent. Disadvantages of 50mm lens: If it is close to the main model, there will be perspective deformation, and it is possible to make a thin face into a wide face. If it is not three-dimensional, it will make the characters look more boring.

85mm is called portrait gold focal segment.

Advantages of 85mm lens: ① it will not cause obvious perspective deformation; (2) compress the picture to make the face more stereoscopic; (3) The blur effect of point light source is very good, which highlights people. There is a natural balance between the blurring ability and perspective of 85mm, and the portrait taken by 85mm can not only retain a certain three-dimensional sense of the face, but also get a blurring effect that is amazing enough for the naked eye. Disadvantages of 85mm lens: narrow field of vision, mediocre shooting effect, lack of sense of scene and story.
