I had the 500 II last year that I used for flying aircraft. With the 1.4xIII attached, my static shots were great. But shooting airplanes in flight (flying away or towards me) resulted in soft images. It seemed like the AF could not keep up. I was using the 1D4. When using the same tc and camera with my 300 f2.8 IS II, I didn't have a problem.

I posted about this before...http://www.dpreview.com/forums/post/52632447

Same here, I quit using the 1.4 on BIF and all moving targets. Static is ok.
