The full frame equivalent of ideal focal length for portraits is < 50mm. It has only to do with rendering the subject accurately without distortion. That's it.

This is bull. First, where do you come up with "less than 50mm?" Second, what's your definition of rendering accurately? If you take a head shot with a 14mm lens, the camera just recorded exactly what that subject looks like from that distance. That is an accurate rendering. The features may appear distorted relative to the image you have of that person in your mind's eye, but if you put your eye at the same distance that the camera was when you took that head shot at 14mm, your eye will see the same "distortion" that the camera did.

You're talking about aesthetics, not accuracy. The camera is always accurate. The human eye/brain combination applies all sorts of non-optical a priori information before presenting the "perception" that you think you are "seeing".

Um the opening in the symbol is greater than.

Distortion...

http://en.wikipedia.org/wiki/Wide-angle_lens

The camera captures a flat plane, a lens adds focal length, a lens is not perfect and can add distortion. In the case of wide angles this can be bad up close for portraits if you intend to be try and capture a faithful head shot for instance.
