We will not see 7D2 to the world Cup anymore, the tester was spanish!  ;D 8)
Could be worse.... Might have been Canadian and never qualified to go.....

Here's my guess:
10 fps
24MP with equal or slight bump in high iso performance
Better weather sealing
4k video @24 fps, 120fps 1080 video
$2300 starting price
Digic6 and a new video processor
Dual sd card slot
AF system like 1DX, but with fewer points
Headphone jack
wifi and gps
articulated touchscreen
wireless flash controller
Wide selection of colours (black). no pink.
still uses LP-E6 battery

It's funny because he was from Canon, it was cameras, but not consumer cameras....

Sorry, I do not understand.

Anyway, I like CR - and I also appreciate the input and contributions of you (Don Haines) as well as you(privatebydesign) to the forum and community. I have learned a lot from the both of you, and I do not want to degrade my experience here, so I will not post any more in this thread. Thanks.
And I appreciate your postings and have learned a lot from you too. I like the fact that we can have a difference of opinion and remain civil to each other... something that seems to be getting rare online.

Getting accreditation for these things is very tough, I know I have to go through the process a lot, but I have never, ever, met someone "working" for Canon.
That's funny... I have :)

and when you have a $100,000,000 advertising budget and have set up technical services to support a couple of hundred "pros" working the event, I am sure that you have no problems getting a few of your people into the mix.

Good. Not sure why it is funny though. If you are a sponsor with a $100,000,000 I am pretty sure you could get whatever you asked for.

Digic5+ - 17 times faster than Digic4
Dual Digic5+ - 34 times the computing power of Digic4

are you sure they got dual digic to do full scaling? I know with past generations going dual seemed to only give 50-60% boost not 100%
A lot depends on how the software is written and what the task is.... but there will always be overhead. My feel is that an 80 percent increase would be almost perfection.... but so much depends on the task and how parallel it can be made.

I wouldn't be surprised if the setup was dual chips, but of different types... one optimized for video and the other optimized for stills.

I really don't think... er, sheesh.

A guy gets a job. He shoots pictures with the camera he's told to because that's what the job is. I don't think he's told to do another guys job, such as shooting press photography, because his job is to use the new camera and try and take pretty pictures with it for his boss who made the camera, not pictures for the press... it makes sense in my head. Am I saying it wrong?

I have never heard of an agency insisting a photographer use a test body, ever. Especially an inferior model to what they most likely have.

Those photographers will generally tend to use the best they can get their hands on. The 1D X.

Like I said earlier, I cover a lot of int. sporting events and will be at one soon. Canon will be there I already know that, but I won't be touching anything other than a 1D X.

If I am paid by Canon to take pictures with a 7D2, that is what I will do. If I am paid to use a GoPro or an iPhone, then that's what I will use.

The goal is not to take great pictures at the world cup, it is to take great pictures with a 7D2 at the world cup.

No you don't need a 1DX. To get 12 fps you need dual DIGIC 5+ processors, but a single DIGIC 6 can do 14 fps. That is the processor currently in point and shoot cameras. And there is almost certainly an upgraded version of DIGIC 6 in the works to provide the additional horsepower for the needs of video functions in cameras. Dual DIGIC 5+ is obsolete.

14 FPS at how many megapixels?  DIGIC 6 is used in PowerShot G16, PowerShot N100, PowerShot S120, PowerShot SX280 HS and PowerShot SX270 HS, which are all about 12 MP.  According to CanonUSA, the max sustained frame rate is closer to 9 FPS (without continuous AF)... not 14 FPS.  What DIGIC 6 camera does 14 FPS at >= 18 MP?

Digic4 - can handle 5.3FPS at 18MP (60D)
Digic5 - 6 times faster than Digic4
Digic5+ - 17 times faster than Digic4
Dual Digic5+ - 34 times the computing power of Digic4
Digic6 - 20% faster than Dual Digic5+, or 41 times the computing power of Digic4

Somehow, I don't think a lack of computing power is slowing down frame rates

Tugela's post implied that 1 DIGIC 6 can outdo the processing of a 1 DX (Dual DIGIC 5+).  Do you disagree?
The DIGIC6 is supposed to have 20 percent more computing power than the dual DIGIC5+, so yes I agree that it is more powerful... but computing power and I/O bandwidth are two different things. I am sure that there are many instances where the extra pins of two chips are better than the faster pins of a single chip.

Computing-wise, if a 60D can handle 5.3fps at 18M, then a single DIGIC6 should be able to handle 100fps at 36Mpixels.... but there is no way the I/O of the DIGIC6 will support that so the comparison is meaningless.

about the only safe statement is that if they use dual DIGIC6 it will be faster than dual DIGIC5+.

Sure it does.  You need more circuitry and processing power to sustain processing higher MP/sec.  To sustain 12 FPS at 18 MP, you need 1Dx processing capability.  More processing require larger/faster memory, processors, buses, etc. and that does take more power even when not used to to its capability.

You seem to be using the words "power" and "energy" interchangeably.  Faster processing requires more power, all other things being equal, but not more energy.

No, not interchageably.  A Chevy Malibu is traveling on the highway (EPA profile) next to a Corvette.  Both are going the same speed.  The Corvette has lower drag and is slightly lighter, yet its highway efficiency is 29 mpg compared to the Malibu's 36 mpg.  Larger components (engine, transmission, etc.) required for greater performance use more power on average and more energy over the same distance.

So far, so good.  But using a thermodynamic analogy isn't a good idea.

Quote
For electronics, components spec'ed for higher performance also take more power even if they're doing the same work.

In most cases, the opposite is actually true, due to thermal reasons and enabled by process technology.  To have a faster device, it needs to be more efficient, not less, or it will get too hot.  If it's less efficient AND doing more work, it will dissipate a lot more power, not just a little, making the thermal management more difficult.

One of the big reasons computers can get more powerful with each generation is that they consume less power per switching event.  If this were not the case, we would have current generation CPUs demanding tens of kW, and burning up during POST.
and don't forget variable clock speeds... when the load is low, reduce the clock speed and save energy....

and don't forget that in multi-core processors you can shut cores down when not needed, further saving energy...

you make a processor faster by shrinking the manufacturing process. Make the transistors smaller and they use less power. Make them smaller and the signals don't have as far to go and they can run faster.

If it was going to be used, then look at low rank teams in the first pool matches. There certainly won't be any working pro's using it in the final.

If it kicks ass there will be.

Except compared to the 1Dx, it won't kick ass.

How do you know? For this application it might well.

But why? Pro sports photographers aren't focal length limited generally so what do they have to gain by using a crop body? The only advantage I could think of would be a potentially higher frame rate as the mirror and shutter is much smaller but even then 12fps is crazy quick, even 10 is a lot

Ummmm....because a more modern camera may have improved ability set and track focus than a 4 year old camera?

You are forgetting the 1D cameras were not designed yesterday, they are old cameras with even older technology. Stuff improves.

Yeah, an APS-C camera that sucks at low light.  What a great camera for pro sports.
The world cup is brightly lit.....

So we make a camera that's really great at shooting the World Cup?  You missed the point.  Pros shoot both indoor and outdoor sports and no one's going with an APS-C sensor considering no pro in the world is focal length limited.  At least, none that I know.

My point isn't that the 7D2 isn't great at action, but it's not going to be good at low-light action and so it's probably not surprising at all that no one saw any pros at the World Cup using one.  I'm not surprised, that's all.
How do you know the 7D2 isn't great at action? Nobody has seen it yet....

There are a lot of sports where you can't get close to the action and you are focal length limited....

One of the possible new features would be tracking of a face or object... having a camera that could track focus on a soccer ball in play would be a fantastic feature to have
