Does the lens generally make people fat? How much fat will there be?
This phenomenon is called lens distortion. It is caused by the zoom lens controlling the far and near viewing angles. Most zoom lenses are a little distorted and vary in size. The effect of making people fat is that the lens is convex, and the effect of making people thin is the lens pillow. Generally, wide-angle lenses and zoom lenses will cause convexity, while telephoto lenses will cause pillow shape.
There are two ways to reduce portrait distortion: one is to use a fixed-focus portrait lens, and the other is to use the portrait end of a zoom lens. The APS-C size portrait lens is 50mm or 80mm, and the Quan Huafu size portrait lens is 80mm or 135mm. When shooting a portrait with a zoom lens, the focal length should also be controlled in this focal section, because the distortion is the smallest at this time.
