I use the 2x with the 400/6.8 and find the quality virtually equal to the lens without the converter. Of course when doubling the focal length other quality issues become amplified - movement - - DOF - etc. So the hit rate goes down a bit. But when it all works the expected image quality is certainly visible. George
