I'm not going to get overly excited about CR1 specs from an "unknown source."

Reserve judgment on a sensor until real specs and results are known (probably won't know that until several months after the announcement). Consensus on this forum seems to be that noise and dynamic range improvements are more important than the number of pixels. Absent a major change/breakthrough in sensor design, I would be surprised if Canon ups the pixel count of the APS-C sensor above that of its full frame offerings.

New battery is a mild disappointment, but I assume Canon would make the change because they have to for design/engineering reasons.

Please, let them keep at least one CF card slot in a dual card system.

New ergonomic design is too vague to warrant comment at this point.

All in all, I'm more excited that we are finally getting rumors about a 7DII. At this point, the content of those rumors aren't as important as the fact that there are rumors circulating.

If we look at what people are unhappy about with the 7D, generally it is to do with noise and image sharpness.  I am not aware of anyone being unhappy with the pixel count.  Canon may however need to up the pixel count to 24MP to match Nikon and Sony, rather than to address any real need - i.e. for marketing reasons.  Assuming Canon continues to flow the same sensor down through its APS-C range, that would be a reason to move to 24MP. - In the market for APS-C (and especially entry-level) DSLRs a lot of customers are still comparing "mega-pickles".

7D is not really an entry level camera. I wouldn't mind 22 or 20 megapixel. Hell, even 18 would be ok. Just better high iso and sharpness would be great update.

+1 about keeping the LP-E6 battery. I use them on my 5D MK3 and 7D. I would not like to give up the exchange flexibility of batteries between those 2 cameras

LP-E6? Well yes... It would certainly be handy if the 7DII batteries were LP-E6 but I'll speculate that the replacement battery will be higher capacity to drive the AF & FPS speeds higher than a couple of LP-E6 cells could accommodate. I'll happily trade the convenience factor for performance upgrades.

Well, on both cameras I use the BG. And, the performance is great (using also Lexar 16GB 1000x) I have nothing to complain

Better high ISO performance, more DR, and throw in built-in GPS and I'm good.

Nah, what I would prefer is a CF/SD combo - that gives far more flexibility - just please not an SD only like the 6D.

I hope Canon will put a good AF there.

if 5d3 isnt dual CF, why should you expect 7d2 is?

But the 7DII will not have dual Digics. Take my word for it.
It will have a single Digic 5+, same as the 5DIII and the 6D.

Here's another math that you can do:
The 1DX has two Digic 5+ processors and a 16-channel readout (official specs).
And the 5DIII has a single Digic 5+ and an 8-channel readout (again, official specs).
Therefore, it can be concluded that the Digic 5+ processor has an 8-channel readout.

Also, the 6D is capable of 20mp @4.5fps with a single Digic 5+ ... and just 4 readout channels (again, official specs).
This puts the throughput of the Digic 5+ processor at 20*4.5/4 = 22.5 MP/s per channel.
That's a throughput of 180 MP/s total for all 8 channels on the Digic 5+ processor.

Realistically, Canon will not go over 10fps in 7DII and will not put dual Digics in it.
So, I'd say that the 7DII will be spec'd anywhere between 16mp @10fs and 22mp @8fps ... with a single Digic 5+.

I'd prefer if Canon puts 16mp/10fps in the 7DII but it's more likely that they will go for 20mp/8fps.

One thing is certain, though: the dual Digic V spec is fake and this whole 7DII rumor is a lame [CR0] rumor.
Could you please provide reference that 6D has a different DIGIC 5+ processor (with 4 crippled A/D channels), than those of the 5D3 and 1D X?

All my references says it's the same DIGIC 5+ with the same 8-channel A/D, which also explains why the same DIGIC 5+ designation (e.g. not DIGIC 5-)

Assuming conservatively that 7D II is to remain at 18MP @8fps, that's ~144MPs, which is still higher than the existing 5D3's single DIGIC 5+ rating of ~134MPs. It's hard to guess how much headroom is left with a single DIGIC 5+, but I wouldn't bet on it. IMHO, it is highly probable, although not a certainty, that dual DIGIC 5+ is a real possibility for the next 7D.

interesting. the channel info is stated on the bh store page(http://www.bhphotovideo.com/c/product/892349-REG/Canon_8035b002_EOS_6D_Digital_Camera.html) so that sounds about right. single digic for the 7d2 and just a made up rumour.

from the B&H link:
"the DIGIC 5+ processor also delivers overall speed and power to the 6D and utilizes dual 4-channel A/D converter"

Looks like the same 8-channel setup to me. At the minimum, I'm betting on dual DIGIC 5 (non '+').

Isnt't the difference between 5 and 5+ just the frequency at which it's clocked? In that case they could easily clock it at some inbetween frequency, or if they managed to improve a bit even higher than in the 1DX, after all, that's what all other processor manufacturers do.

+1 for better DR and improved ISO performance. I guess it will come down to how improved the read noise is going to be...

Also, I would appreciate if it did not make the 100-400 look bad. Just ordered one  ;D

Cheers!
