Is a stop or half a stop that important? Pentax made a fine 500/4.5 MF, and I think still makes a 400/5.6 AF. Both Nikon and Pentax made 600/5.6s, which would be lighter than the 600/4s, but you are probably looking for an AF lens. If Pentax made a 400/4 it would probably be pretty big. I've thought at times that I'd love to see a 400/4.0 from Nikon but considering the size and cost of the 400/3.5 from Nikon I'm not sure it'd gain me much. Contax does make a 400/4 USM IIRC. DJE
