Why is 35mm lens called humanistic lens? Is there a historical origin?

It has a certain historical origin, 35mm.

This lens is called quasi-standard lens, and its viewing angle is about 64, which is the most commonly used lens. People often joke that this lens is a standard lens and a wide-angle lens of the subject. Because its viewing angle is not too large, the edge deformation is relatively small, and the depth of field is larger than other lenses with the same aperture longer than 35mm, it is very practical to take some photos of documentary themes, scenery and few people. The humanistic photos of some famous photographers in the early days were all taken with 35mm lens, which had a great influence on later generations. Today, 35mm lens is considered as a necessary lens for humanistic photographers, and it is also a small favorite!
