*UPDATE* 5D Mark III Sighting?

[akiskev]

Another thing that indicates it is a 5D3, if you look at the size of the optical viewfinder opening, the 5D's is slightly larger than the 7d's  ) relative to width of the Flash holder; on the mystery camera, it is more like the size of the 5D2/ FF.

In the attach pic, it's a crude approximation of the relative sizes of the view finder. & has the smallest, 5d2 is larger and mystery camera is as large as 5d2 (if not more), and visibly wider than 7d.

Thanks for the picture comparison, it made me look closer. But I cannot draw the same conclusion as you did. When brightening up the "mystery camera" picture, you see the edges of a smaller viewfinder than the 5D's inside the dark cutout - just like you see in the 7D picture you posted. On the 5D picture, there are no edges visible - only corners (inside the viewfinder). Now if you look at the mystery camera prototype and brighten it up, you do see edges - even though the camera is angled slightly to the side, you see full side edges on both sides. Note the blue spotted line.

To me, this still leans heavily towards the 7D.

I agree. It surely isn't a FF viewfinder.
here is a corrected image by me:

1DX also has a black cutout in the viewfinder.

Not only 1dx but older 1d-ds series too. so... ?!?...

Ah, now that's interesting. :-)

Back to 5D mk3 again (which is more in sync with the other rumors as well I guess). Nice new button layout, yay!

[CanonGuy]

Like many others said looks like 7D Mk2 same buttons(except few newer buttons) in same places but doesn't have build-in flash.

I would suggest for Canon to make a "mode dial lock button mark II" with on/off positions, so it won't be necessary to push it each time you use the dial.

Not read all 21 pages (seriously guys? no one here works?) But my guess is the RATE button will switch between frame rates quickly in movie mode. May be a sign there's more options....

Going by the placement (alongside review, delete, magnify etc.) I'd guess it more likely to be in the sense of rating images. Happy to be proved wrong though...

IMHO, it's just one more button that could be reassigned to do something I really need. That's great!

Given that it is blue, same as the "play" and other review buttons, I've also been assuming it is to rate each photo as you are scrolling through.  Something like hit the "rate" button and the 5 stars show up and you rate the photo. 

I don't use this feature but maybe "rating" photos is very popular.

which makes only one possible conclusion: The cutout in the viewfinder has nothing to do with whether the mystery cam is ff or not.

+ 1 for that. Exactly ! We wont know until some new info will leak (or be presented).

Well, could it be a 70D?

[Tijn]

Well, could it be a 70D?

No, not without a flash. 70D is too consumer-oriented. It has all the portrait, macro, auto-flash preset modes and everything for those who don't want to watch apertures and shutter speeds. Being able to flash (even if it's crap) has a high convenience value for those people.

You are right. 70D is a consumer model with all consumer features like modes and etc.

What makes me think that this isn't a 7d replacement is for 3 reasons: 1st.: No pop up flash, 2nd.: no creative mode on the dial, 3rd.: Viewfinder size

First reason is valid.
Second reason goes for 7D but also for 5D mk2 (it has this mode, also), so that doesn't work.
Viewfinder size works against the FF theory, not with it. It has full side edges, as does the 7D but not the 5D mk2. 1D X does have inside edges, but they're more narrow than the edges on this mystery body.

Lots of good discussion.  I'm not sure if this has been mentioned, but the battery door/compartment for the grip has definitely been redesigned, likely because of the inclusion of a joystick on the grip.  The battery door and release do not appear to be on the same plane as the back of the camera anymore.  From what I can tell, it looks like battery(ies) will load on the side, similar to the 1D series.  The grip also appear to have a lower profile on the back, which is a welcome change.  It looks significantly more ergonomic than current grips.

Can't help wondering if this new camera is targeted at wildlife photographers, some of whom seem to feel overlooked with the 1DX. The testing location and lenses used would also tie in with this theory.

Perhaps it is a new higher MP APS-H.

Hypothetically, if you were setting off on an African Safari to shoot wildlife with a couple of long telephoto lenses, presuming you had to make a choice between FF and APS-H what would you use? What do most wildlife photographers use now? The Canon Employee was taking photos of a  bird, when I want to take bird photo I use my Aps-C for the crop-factor although for most things I favour FF.

I'd love this to be the 5Dii replacement and I bet it's going to be announced very soon  but... it also makes  sense that the camera in the photo may be something else.

Did somebody notice that the diopter adjustment is set very far back into the body? There is also some kind of "hole" left from it. The adjustment wheel should be centered, which it isn't.
