Don't get a 2X for that lens. I know. The focal length is so long as to make hand holding almost impossible, even if the IS does still work, and it does. Manual focus is a necessity and difficult due to darker viewfinder. And a tripod become a necessity, which kind of defeats the purpose of the lens in my opinion. Quality goes way down due not only to softness but to shake. You have to shoot at high ISOs because you lose 2 stops and need a very high shutter speed. And wide open is of course the softest. I use a Kenko Pro 300 1.4x on my 100-400L IS. It practially lives on the lens and I'm very happy. I shoot birds.
