What is the low light AF spec. In EV for the EOS 7D MK II ???

Or is that -2?

Yup, -2ev. There is no point for -3, since 7D II is an outdoor camera.

Maybe, they'll put -3EV on the very center point, which will be as well sensitive down to f/8. For marketing reasons alone, this would make sense, but let's wait :)

For marketing reasons, this is the exact thing they won't do as they try to keep "low light ff 6d with crappy af" and "machine-gun fps crop reach 7d2" apart to make you buy both :-o

Any one know!

I don't know either, probably -2lv like on the multi-point 5d3 af array?

But what's the use of very low light af on a crop camera? This isn't built for high iso, so if a crop camera cannot af anymore the shot will be crappy anyway. And for tripod, you can use the lv af (and probably Magic Lantern's night vision mode) which doesn't have the phase af's limits.

Pfft, I already have 6D and original 7D and I'm quite happy camper - Canon already milked me :D

Truthfully, all I'd really like from Canon is an updated 50mm lens, whether 1.4 or 1.8 is of no matter, as long as it's on par with recent 24/28/35 primes. And maybe a new 85mm would be nice, I don't need Otus sharpness, all I need is 35/2 sharpness :)

I would have thought it was more important to have the higher precision of the 5DIII AF.
Precision
5DIII > 6D

To be precise (and unfortunately for me as a 6d owner): 5DIII >>>>>>>>> 6D.

Next to the missing cross-points on the 6d, only the 5d3 (and 1dx (and 7d2?)) make use of the enhanced precision of the latest Canon *lenses*! The 5d2-derived 6d af is still designed for the previous generation (see lensrentals' posts on this). As discussed multiple times, the -3LV is seldom necessary - I should do a poll how many people actually need it.

The -3 on center would be awesome, not that -2 isn't an improvement over the current -0.5.

for what the 6D is meant the AF works perfect.

i use if for macro, landscape and portraits and the focus accuracy is perfect.

thought i have no 85mm f1.2 only a f1.8 and a 135mm f2 but i can´t complain.

i doubt the 5D MK3 can do better in thoses cases.

Exactly. Example of the difference between -2 EV and -3 EV: f/2.8, 1/15 s, ISO 51200 vs. 102400. Neither likely to give a good result even on FF, and I don't know that the 7DII expanded ISO even goes to 51200, much less 102400.

The 7D MK II is not a low light camera, so I don't think they need a AF module to focus lenses where the camera can't capture a image in any event.

Don't be fooled by the high ISO specs for jpeg images. Canon plays fast and loose with these numbers. We will want to see the raw capabilities rather than jpeg with a ton of NR. The real high ISO might beat the 70D by 1/4 stop if we are lucky.
