My 70-400G is already fast (with A99). I can't wait to see how fast the new one can be.

Its fast at 70mm but is it fast at 400mm not quiet .

here is the existing 70-400G on A55 skip to 16th second http://www.youtube.com/watch?v=YmSkWTpdE6M

For comparison here is the improved newer 300G f2.8 SSM2 http://www.youtube.com/watch?v=0Go5c1EJJ2g

So the new 70-400G should be atleast as fast as the new 300G F2.8 with SSM2.

Boy that 300 2.8 II was fast!

I briefly tested original 300 2.8 G on A99 and it was as fast (or ever so slightly faster) as 70-400G. In real life I have no problem AF tracking moving subject.

I guess it's all depending on street pricing, if the new 70-400 selling for $2200-2300 I might upgrade, otherwise I am perfectly contend with my silver version.
