Most fast teles are designed to be optimum at wide f-stops. Stopping down to f/8 usually will only improve the edge very slighty - unless we need more depth of field. At some circumstances f/8 would result in a shaky/blurry picture. Shooting at f/8 is not a complete madness, of course, but most of the time I use my 180/2.8 at f2.8-5.6.. I just remembered that even my F300/4.5 is superb already at f/5.6!
