Bahhh, ele viu no LCD da máquina 

Onde está o ruído?!!?!?!? Bolas é muita areia... 

Esse ISO nao esta correto, nao existe na 1DX, ele usou o H1 que sao 102400. Nao se deve confiar sempre na exif, ainda pra mais quando a maquina ainda nao saiu.

Canon’s new 1D X is an impressive fusion of the old 1D and 1Ds lines, boasting state of the art sensor quality combined with impressive speed, but there’s one downside that may be a big disappointment to some photographers: the camera loses autofocus when used with lenses with a max aperture of f/8.

While there aren’t any Canon lenses that naturally have an f/8 maximum, adding a 1.4x extender to a f/5.6 lens or a 2x extender to a f/4 lens results in a lens with a max of f/8. If you’re planning on upgrading to a 1D X but need extended reach (e.g. you do bird photography), you may need to shell out some extra cash for a faster lens.

epah, assim já não a compro 

Grande lacuna, mas enfim, quem tiver uma dessas de certeza que possui boas objectivas a fim de evitar o recurso a extensores... penso eu...
