Does anyone have an example of what Canon call revolutionary?

White bodies?
I heard it will come out in midnight camouflage....

I did a quick drawing of the idea....
The thing about this arrangement is that it uses single-color (monochromatic) filters.
So, you are still 'throwing away' 2/3rds of the incident light.
The trick would be to use more transmissive filters (say R+G, R+B, G+B) and thus throw away less than 2/3rds of light.
Your arrangement does improve resolution, though.
interesting.... so you think that it could be done with the more transmissive filters? the combination (if it works) could get to only throwing away 1/3 of the light, as opposed to the current bayer which throws away 3/4 of the light.....

I have wondered for a long time why the bayer filter has survived. Instead of breaking up a pixel into 4 squares, G-G-R-B, why can't it be made into 3 rectangles of R-G-B where the colours no go from 25 percent of the area to 33 percent of the area and you gain about a third of a stop?

Now imagine each pixel made up of 6 subpixels, 3DPAF pairs, and alternate the orientation of adjacent pixels so you can do DPAF in both the vertical and the horizontal plane.

that would certainly be a logical growth from what is in the 70D....

I think if you have quad, each pixel can do horizontal, vertical and diagonal in each direction phase measurements.  So, no need for six.

The idea of six subpixels is to have pairs for DPAF, and the three pairs gets rid of the current bayer sensor with half the real estate devoted to green. This improves the sensitivity of red and blue by a third of a stop.

I did a quick drawing of the idea....

This may be one of Canon’s best kept secrets as it’s apparently going to be more than an “evolutionary” technology.

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.
