Why did Xsmax shoot such a big person?

Because xsmax lens is a wide-angle lens.

Because xsmax lens is a wide-angle lens, the perspective deformation is very strong, that is, the perspective effect is very obvious.

Xsmax's focal length is too short (the picture is wide), so you need to put your face closer. It seems that the deformation is serious (near the big and far from the small), and the deformation of the five senses will be exaggerated. Of course, if you make good use of this feature, you can also make people's legs look longer (from bottom to top).

If the focal length is too long (similar to the telescope effect), people need to shoot farther, and their faces will appear flatter and fatter, but this will have a better background blur effect; Generally speaking, the focal length of 50mm-85mm is most suitable for shooting people, which is closest to the visual effect of human eyes.
