This past Sunday I was able to borrow a 2x tele-extender for a few hours. Well, I fell in love with it, ordered one first thing Monday morning, and today it arrived. The loaner wasn't compatable with my 1.4 II because it was an older non-"II" version, but this one is! Behold my 680mm f 5.6 backyard bunny! He's about 50 to 60 ft away.

So it's EOS 40D / 1.4x II / 2.0 x II / 70 - 200mm 2.8 IS L .
Autofocus works fine, but it does 'hunt' some. Plenty fast though.
This is gonna be fun.
