I didn't test it myself, but used the comparisons at www.photozone.com which
rates the AF speed of the 70-200 with 2X TC at 61 out of 100 and the 100-400
at 86. Based on that input, I imagine it would be noticeable.

Kim,
Now I get it. Sorry, I had originaly thought it implied msecs instead of a
score. I too have the 100-400 and eventually sold my other Canon zooms.
It is very good for sports.
BTW, how much do you use focus tracking?
I find that for many things single shot and sometimes manual offers more
control when it comes to baseball which is what I am primarily using it for
these days. Just curious.
