I wouldn't be surprised if Canon actually does release a 600mm f/4L DO IS and 1000mm F/5.6L DO IS at the same time. The 600 DO looked to be somewhat smaller than even a 400 f/2.8, so I'd imagine that they could pull off a 1000mm DO around the size of a 600mm or 800mm. That would be a much more temping upgrade to the 800mm than simply updating it.
Kinda in the same way that Canon did the 500 and 600 at the same time.

200/2 MkI is close-to-perfect... would MkII IQ get much better... not sure weight reduction alone would merit "trading up"

Always seemed like an excellent discreet public candid combo. Though I suppose the 55-250STM does about the same.
tron said:A 600 4 Do would be a hell of a lens but I am sure it would cost a five figure amount...
If only they made - I am sure they will not - a 600 5.6 DO too, it would be fantastic... Same length with a 600 DO more or less, but with less diameter and weight and cost than a f/4 version... It would make a fantastic portable birding lens...

I was shooting next to a newspaper photographer at the weekend who had the first-generation EF 300/2.8 and 600/4. No IS, nothing. Just lots of black gaffer tape to keep things in place.
He said they keep cannabilizing other ones in the office to keep a few going since Canon don't service them anymore, but they're razor-sharp and they actually sent the 'replacement' Mark IIs back because they drained the camera batteries much faster and weren't discernably better in terms of IQ.
Khalai said:But you can always turn the IS off to save some juice in batteries. But once you paid for it, it makes a little sense to turn it off, right?

Yes, I guess it's another thing that can fail and make the lens inoperative. Plus there's a host of other circuitry in modern lenses.
I've never heard a 1DX ( might have been a Mark 2 ) with such an insane frame-rate as when he fired with the ancient 600, I wonder how much current the modern lenses draw in comparison.

But the old 300/2.8 has focus-by-wire - if that fails you have no way at all to focus. The IS versions have conventional ring USM so if AF fails you can still focus manually. And if IS fails you can normally still shoot without it.
This kind of discussion reminds me of conversations I used to have with people who ran very old cars. One justification was that when they broke down they could carry out running repairs at the roadside. Sure, I would say, but my modern car has never broken down...
LonelyBoy said:I've had the same argument about car windows, manual vs powered. No matter how reliable power windows are (mine have never failed, including a VW), I know people who rant about manufacturers "forcing" them to buy "another thing that fails". Nevermind that my old Civic had its driver's side manual window fail...
neuroanatomist said:The 600/4 DO seems likely. Nikon recently launched an 800/5.6 lens, so I could see the possibliity of a 800/5.6 II from Canon.
But who knows...maybe they'll surprise us with something novel. How about a 400-800mm f/5.6L + 1.4x TC, modeled on the 200-400/4+1.4x?
ERHP said:600 f/4 IS w/1.4X TC built in. Or better, dual select-able 1.4X TC's built in.

if they came up with a 400-800 zoom, based upon the 200-400 zoom, I think they would make it F8. The 200-400 was a stop slower than the fast prime at the long end. Think Canon would do that again to avoid make the lens a monster.
neuroanatomist said:It would already a bit of a stretch for Canon to release a native f/8 dSLR lens (built in TC means 'native'), but I can see it happening now that bodies even down to the xxD line have f/8 AF points across the frame.
