1.4x converters Sigma ExDG v CanonmkII (1 Viewer)

Has anyone got an opinion on which one is the best to use with a 100-400mm ? I am aware that there are focus problems, but I use a teleplus pro 300 DG at present (taped pins) and wonder if I could get better IQ with the latest siggy or mkII canon. Can't afford a new mkIII !
Thanks for reading,
Andy

I have tried all three and would say that on a 100-400 you are best of sticking with the Kenko.

I also think the Kenko Pro is as good as the Canon MkII. Not used it with a 100-400 though. The main thing I find with using tc's with a slow lens (e.g f5.6) is that the image often lacks contrast straight from the Camera, nothing that cannot be easily fix in post though.
