Supertele choices

[HDNitehawk]

If they (Canon) would see fit to allow f/8 AF then it would be a no brainer for birds .... the 800mm +/- the converters

You know we should think that, because all the other supertele's with the 1.4 converters are fairly usable. My impression of the charts is that the 800mm with the 1.4x is kind of weak. Naked lens though it would be great way to go.

@HDNitehawk (Rick), I agree, its not that impressive.

The 600mm II +1.4x looks a little sharper, with less vignetting than the 800mm f/5.6

@Joel, I also wish the new bodies handled center AF f/8 maximum aperture, but couldn't you still use that combo in live view mode for "stationary" birds on a tripod at 1000mm-1200mm?

Yes you could and I have used manual focus on the 1D4 at 1000mm because AF had trouble with the specific circumstance....low light, small bird standing in rushing water. Probably for anyone who concentrates on birds more focal length is better, I do not own a 1DX (yet) but I think using the new 600 or the 800 would be the way to go for birds.
