do autofocusing with 100-400L and 1.4X TC (or any lens combo that has a max aperture smaller than f5.6)??? Inquiry minds want to know....NOW! :mrgreen:
Just read a post in the other forum where Chuck Westfall says the 20D does not AF with aperture smaller than f/5.6. :( Of course I don't doubt him but I just wanted to get a verification.
