Fortunately, portraiture, landscapes, 'art' photography, meteorological and night-sky photography are almost all of what I 'shoot', so the camera's weaknesses, AF-wise, don't matter to me. If I'm shooting hand-held, I'm almost always using just the center sensor, anyway, so 11 vs. 61 sensors and which ones are cross-type isn't really a consideration, either. Near as I can figure, I'm just about dead-center in the 6D's target audience.
I've done hand-held astrophotography with the thing. Mind you, it's wide-angle planets-and-moon in deep-ish twilight, but it's still astrophotography.

Interesting, mine is on the left - as seen from behind. 
I think you're right. I was conflating the DOF button on the EOS Mount with the DOF Buttons on Olympus OM film camera lenses.

Canon would have to come out with a function like a depth-of-field indicator to tempt me to switch from my 6D. So far, this camera does all I need in full frame camera.
There is that button on the lower right side of the lens mount- as seen from behind. (Every EOS camera has that.)

It depends on the filter, there are special filters just made for the use with wide angle lenses!
They have narrower than usual frames.

Those videos are chemically pure bovine excrement. There is no planet 'Nibiru'.

Shouldn't that have read '370HSSV'?

Unless there's something wildly outside the usual specification tolerance, the difference in T-number between two lenses of similar F-number and 'vintage' isn't going to amount to a big difference in shutter speed needed to correctly expose in a given illumination. Big differences in the number of elements (i.e. prime vs zoom), a big difference in age (resulting in one lens having better AR coatings than the other), or the glasses used in a design can make a bigger difference in T-number, though.

If you mean "Is the intensity at a given place on the sensor the same for all those lenses at the same f#?", then yes. If you have a patch of, say a wall, in each lens' field of view, each lens will gather an amount of light from it proportional to the square (area) of its aperture, and each will focus that light into a patch of a size proportional to its focal length. The area of that patch will vary with the square of its linear size. So, a 100mm f/2 lens will gather 4x as much light from that patch as a 50mm f/2 lens would and then will spread it into a patch 4x the area on the sensor as the smaller lens would-- the intensity of the light within the two patches on the sensor would be the same. (I'm ignoring the effects of manufacturing variation in actual focal length, difference in transmission, etc.)
If you mean something else, then maybe not.

Is the amount of light entering the camera the same for 28mm, 50mm, and 90mm if each is set at F/2 and all other factors are the same? Thanks.

Indeed. Take one (or more) photo without her and as many as needed with her and photoshop as needed. It's artistic, not phtojournalistic, so no problem.
Part of the point of the effect is that the grass seen through the mirror frame has to match up with the grass behind her. Good luck with getting that unmanipulated.

What I'm not seeing, which I would expect to, is the back of her right calf reflected in the mirror.

I suspected in-camera HDR at the outset, and that has finally been resolved. What I find most useful from this post is the clear demonstration of what size of area the camera manipulates around the airplane and the effect it has on the "noise" in the sky.
Indeed.

I read that the new 6D2 will be released around Semptember of this year.
At this point, there would have to be big improvements for me to not simply buy a second 6D-1 at discount or used when the 6D-2 comes out.
I like my 6D-1 that much.

I mostly shoot handheld and using only the center AF point.
