Just had a quick hands on with the Canon 5d mrk3 (about 2mins to look over it)
Here are the few images I took
The first image was in manual mode,, the others in the fully automatic mode
Sorry for the bad quality, these are just point and shoot
Lense was the newer 28-70mmhttp://s1184.photobucket.com/albums/z331/ianpowell76/5d%20mrk%20III/

The layout of the camera is the same, though it felt different.
I say different as they have done something to the paint finish that made it feel different.
I would hate to say the build quality was less than the 5d mrk1 and 5d mrk 2, which I both own..
You'll see when you get one..
Then the actual functions of the buttons are in different places.
Such as the zoom of the shot you have just taken operates in a different way.
To zoom you have to press the magnify button located to the left of the display screen, but the function of the zoom is controlled by the dial wheel next to the shoot button.
Maybe this is a default setting ?
The Focus is better than the older models,, was fast and didn't have focusing.
When looking through the view finder, very pleasent to see an array of focus points.
As I said,, I had a limited time with the camera,
Will be getting it, to add to my collection..
