As I may have mentioned once or twice before, a huge national controversy has been sparked by photographs of beaches taken with telephoto lenses, which, as you know and I know, but apparently nobody else knows, exaggerate how crowded a scene is by exaggerating the size/closeness of distant figures.
The distance-distorting effects of zoom lenses are an important issue in taking portrait photographs as well. Here is a portrait shot at 50mm focal length, which best represents what the human eye sees:
And here is what he looks like with at the various standard zoom focal lengths from wide-angle to telephoto:

A 50mm lens is roughly what the human eye sees. A wide-angle lens (focal length less than 50mm) exaggerates the size of that which is closer, such as the nose in a portrait and understates the size of that which is further, such as the ears in a portrait.
A wide angle lens makes your face look skinnier, a telephoto lens (>50mm) broader. If you are fatter, you’d probably prefer wide angle. If you are skinny, like most male models, a telephoto lens makes you look more formidable.
As you can see in the above example, a wide angle lens (20mm = 0.4X while 200mm = 4.0X) makes you look more Jewish, a telephoto lens more Gentile.
