Mark, no offense, but I'd call that unuseable. Is that with your new lens? Was that MF with the view at 10x? With a 2X converter you've probably got really slow AF and it might not have caught up OR you need to set your camera's front/rear focus with a +- adjustment. I think your camera allows for AF fine tuning, including with a TC combination (so long as the camera recognizes your TC). If the camera doesn't recognize your Kenko, it'd be one reason to go with a Canon brand TC.
