It's hard to field test equipment like that without somebody noticing. 
Ooooh ... 

Shows camera back in more detail here.

More interested in the lens. Any have some conjecture, wild or otherwise. 200-400 with BUILT IN tele converter? So what's that make it a 560? I mean nice idea, less opening the lens to dirt and dust every time I want to "go long". One less piece to carry. Hey one less lens to carry?

I'll go out on a limb and say this isn't your f/5.6 either from the size of it. Looks like it could be a f/4 at the lower end and that would be f/5.6 with the TC engaged, BUT maybe the auto focus would work on something other than the 1D series for a change? (300mm f/2.8 with 2x converter on many cameras, other than the 1D#, very jumpy random at best, in effect, loses auto focus.)

Here we go again. Do I sell four of my telephoto lenses to buy this one?  

Oh price... guestimate? IS/USM f/2.8 $2669.00 List f/4 and $6000 List (just took me out of the game)

Mode switch 1.4x makes it 280 - 560 That's cool.

I want it Right Now!!!  

Gone, 70-200, 35-350, 100-400, 2x TC... just this one and a wide zoom.

(revised to downgrade high expectations)

Will they come out with a lower price model with no built in TC?

Good news I'm safe until next year, because I won't be buying a new lens in August. That's usually Springtime adventure.

I've created a mock-up of the spotted camera using a current 7D and the info from the 'spy shots'

Thanks Leaf!  I�m not sure I like the placement of the on-off switch�and a feature I would have liked to have seen is a dial lock on the mode knob that allows you to lock into M, TV, or AP mode�I already bump it enough.

Interesting placement for the �rate� button as well.

Yeah, I bump that knob quite a bit as well.  All of a sudden I find myself shooting in C3 with some crazy settings. :S

want!

Glad I'm not the only one. It does look like the mode dial has some sort of button in the centre on that earlier shot - maybe I'm imagining things...

Isn't that the purpose of the lock button? That's why I thought it would make more sense being swapped with on/off. If that's not what 'lock' does, what would it do? Lock all controls? What's the need for that?

I really hope they change the way you switch between manual video and still images too - drives me nuts having to dig into the menu to change over the live view mode between "exposure simulation" and movie mode.

I have C1 dedicated for movies -- there are so many changes that have to be made (live view, picture profile, ISO, etc.) I can't imagine doing it any other way.

Thanks, Ed. I did get that, but what I don't get is the purpose of the switch labeled 'lock' at the bottom (where the on/off switch is on the current 5D2).
