I've used it for action in a pinch, but if I know I'm going to be shooting action or BIF, I'll grab the 7DII.

Your camera already has it, its called a depth of field preview button!

6D is a great camera, it out performs the 5D mkiii in dynamic range, I recently purchased a 5D mkiv only after confirming that it performed as well as the 6D when shooting at high ISOs. It does, but the mkiii does not. You will like this camera, I sold my when I made the decision to purchase the 5D mkiv but never regretted owning it. One note is that the max shutter speed is 1/4000 so you have to take care when shooting with a fast lens in really brightly lighted situations. WiFi and GPS is a bonus that does not come on the 5D mkiii either.

I think a look at the DR charts for the referenced cameras would be instructive. You'll note that the 6D and 5D3 are virtually identical with respect to DR from ISO 300 up, and the the difference between the 6D and 5D3 from ISO 100-300 is very small (~ 0.3 stops). On the other hand, the 5D4 is certainly better (roughly 1-1/2 stops) than either from ISO 100 to 500, but almost exactly the same as either from ISO 500-600 up. Just select the bodies you want to compare, and look at the DR:http://photonstophotos.net/Charts/PDR.htm

One comparison I've seen where the 6D out performs the 5D3 is in Low Light Auto Focus capability.

I have read that as well (that the 6D will autofocus at -3EV and the 5D3 at -2EV), but overall, I think everyone will agree the the 5D3's autofocus system is superior to the 6D - autofocus at f8 minimum instead of f5.6, more AF points (61 vs 11) and 41 cross point for the 5D3 vs 1 for the 6D. In fact, the autofocus system on the 6D is it's biggest drawback compared to the 7D2, 5D3 or 5D4 when used for sports, BIF or action shooting. Not knocking the 6D - great for portraits, landscapes, etc, but the AF system is it's biggest drawback for some types of shooting. What I was addressing was the repeated assertion that the DR of the 6D is better than the 5D3, and the chart I referenced shows there's no difference above ISO 300 and only 0.3 stops from ISO 100-300 - an inconsequential amount - their DR performance is virtually identical (but the 5D4 IS substantially better than either below ISO 400-500 and has a number of other advantages - I'd love to have one 😀)

No doubt the 5DIII AF system is MUCH better, but when I bought my 6D (as a supplement to my 7D Mark II), I could have paid roughly TWICE the price for a 5DIII. After one year of using the 6D, I'm glad I got the 6D - In my humble opinion the best bang for the buck for a very decent full frame camera. I could see myself one day parting with both the 7DII and the 6D for a 5DIV - but no time soon.

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.

I was responding to another view about how my A2 had a user defined mode ( not DOF preview) where you could look through viewfinder and push a button twice to specify near and far DOF; camera would then set correct aperture.. seems like it would be a nice feature. Instead of looking at a table if DOF was really important.
