Gentlemen, I believe I was onto something by suggesting the spy shot may not show the camera at 100% view playback, although it's probably not 200% either. Let me explain.
My Nikon D300S has a 640-pixel wide display, produces a 4288-pixel wide file, and lets you zoom in during playback to precisely 400% (Nikon calls this "approximately 27x" in the user manual, since (4288/640) * 4 = 26.8, but I find that terminology confusing; 400% means much more to me). The D300S also allows 200%, 100%, 50%, etc.
I looked up the user manual for the EOS 60D, since it's a recent Canon SLR with a 720-pixel wide LCD. Canon uses the same confusing terminology as Nikon, but says the camera can magnify up to 10x in playback. With a photo width of 5184 pixels, that equates to a 139% view; very clearly not 100%.
Since that's not the behaviour I expected, I also looked up the EOS 5D Mark II user manual. Guess what? It also allows a magnification up to 10x. But with a photo width of 5616 pixels and an LCD width of 640 pixels, that now equates to a 114% view.
The EOS-1D Mark IV magnifies up to 10x (equates to 131% view on its display).
The EOS-1D Mark III magnifies up to 10x (equates to 82%, i.e. this camera can never show the full file detail on its rear display).
The EOS-1Ds Mark III magnifies up to 10x (equates to 57% view, i.e. you can't even get close to seeing the full file detail on the display).
In other words, Canon cameras do not typically show 100% view in playback mode. They show 10x magnification instead, and depending on the sensor and LCD, that may be more or less than 100% view.
This means all our previous calculations are wrong, or right only if 10x magnification = 100% view on the "5D Mark III", a very unlikely scenario.
