See the plastic chassis, see also that the lens mount is still attached even though the magnesium skin has been removed - the skin is just that, a skin - not structural.

Sorry it is simply a fact that all Canons apart from the 1D series have plastic chassis.

More BabelN2 fantasy.

The magnesium shell acts as a structural exoskeleton and everywhere it is screwed, it is screwed into metal and not plastic. It is not simply a cosmetic 'skin' as you suggest.

Also clearly displayed in your photo is an additional metal reinforcement going from the lens mount to the tripod mount. This magnesium exoskeleton to steel internal extensions exists throughout the camera.

Here you can see the steel frame that extends from the 7D exoskeleton and provides structural support to the back of the mirror box.

So while the mirror box is engineering plastic, it is not the 'structural chassis' as you fantasize.

Over 19,600 posts and the misinformation continues to spew forth.

I’m BabelN2,

it’s my gratifying task

to tell you all you need to know,
you only need to ask.

the seas are thick with elephants,
the skies are purple straw,

you measure with an octopus,
you hammer with a saw.

I’m filled with facts and figures
I gratuitously share,

The stars are silver footballs,
tangerines have curly hair.

Gorillas fly at midnight,
and a month has seven years,

tomatoes play the clarinet,
bananas have long ears.

I’m BabelN2 ,
and there’s nothing I don’t know.

The moon is chocolate pudding,
macaroni grows in snow.

A buffalo is smaller
than the average bumblebee—

If you think of any questions,
simply bring them here to me.

Apologies to Jack Prelutsky
