I think, EF II version is providing a better image. By the way, the RF 600mm f/4 L with 2X does not do as well as EF 600mm f/4 L with 2x III.

What surprises me is that although canon has optimized the $20K RF 1200mm lens (with the extender slapped to the back of it), in terms of sharpness it does not appear to do as well as the old EF 600mm II version with 2X III extender.

I have never tried my 600mm with my 2X III, having seen this, I am now very motivated to test it.

CA is horrendous on 600 f4 II + TC2 III. and that goes for the sharpness and contrast.
