Il 300 lo ammazzi con il 2xIII...
Perdi luce e nitidezza. A questo punto prendi un 100-400 e lasci com'è. L'1.4x va meglio del 2x ma in ogni modo si mangia uno stop pure lui.

Le differenze tra il 100-400 II moltiplicato 1,4 ed un 300 f 2.8 duplicato sono molto contenute con un lievissimo vantaggio per lo zoom. La differenza forse più tangibile si avverte negli inseguimenti a soggetti in volo, il 300 duplicato è un poco meno reattivo, ma se il soggetto è ben tracciabile, anche il 300 + 2X si comporta decentemente.

Questo è un confronto che ho fatto io un po di tempo fa, il fuoco era sui "pannelli rettangolari grigi":
