My 400 5.6 works very well with the Kenko 1.4x TC on the 6D. If the 6D had (or gets) Canon-blessed f8 focusing, I might be tempted to pick up a Canon 1.4x TC III. But there's no sense in doing that if they don't bring f8 to the 6D.
Nice shot, btw. Must be very nice having IS on such a long lens. That's the one thing that's tough about the 400 5.6 and 1.4x TC combo. Really hard to hold still with it.
We've had snow every week for the last four weeks. For May, we've already beat our annual average.
Yeah, 1000mm at 1/400-sec. doesn't work without IS. Lack of IS is a reason to consider the 100-400mm or a Sigma. None of those work as well as the big Canon primes, but you don't have to sell any cars to own them.
Now that I've got 1000mm, I'm torn between the 500mm and 600mm Series II lenses. The IS on both is supposed to be two-stops better than my Series I. That would be simply amazing. There's talk that they may finally update the 100-400mm with a Series II. If it got the new IS system, that'd be a great bargain. Of course the price will go up a ton, but, if they kept the increase under $1,000, that'd be a comparative deal.
