What lens is good for Canon SLR portrait photography?

When shooting portraits, a 50 mm fixed-focus lens is the best ... The larger the aperture, the better the effect.

F 1.8 is enough, F 1.4 is awesome, and F 1.2 is the best.

If the shooting distance can be longer, then the 85mm large aperture fixed focus lens or even the 105mm large aperture fixed focus lens is an ideal portrait lens.
