I am on the list! I am hearing it will be released the end of Jan:)
From looking at those images it looks as though I'll be getting in line.
Looks like it only "autofocuses" with some of the lenses.

Looks like they use f5.6 as the theoretical stop for autofocus functionality. I've used a 2X on my 600mm F4 and it does autofocus with enough light...although with the old 2X TC the image quaility is just not worth it. Interesting to see how this does on a really long lens.
Not really a good test : too much USM on the images, especially crop ! :(Quote:

Secondly, I can't fathom why he'd try and use it wide opn....like all other TC's, it won't be at it's best until stopped down.
