It's not double resolution... It's double color data that has been shifted slightly. Each split pixel uses the same bayer layer. but what this does is create a higher sized file with more color data for the same resolution file. If you look at the specs the size didn't increase but the data dramatically did.

Isn't this sort of like Foveon tech? So what we'll end up with is a sharper image with better color and lower noise since each pixel probably cancels SOME noise out...

I'm uber excited to find out what exactly it does though!

Foveon is very different - instead of a colour filter array it has a stack of layers, sensitive to different wavelengths of light.

AFAIU Canon's DPAF sensors have double the resolution (i.e. twice the pixel density, horizonally) - in the sense that each pixel is actually two, and using Liveview AF it can use that data to achieve phase autofocus. Prior to these new 5D4 rumours, the pairs of pixels have always been read out as one for the purposes of taking an image. I assume each pair would be under the same colour in the filter.

I'm not sure I understand "a higher sized file with more color data for the same resolution file"?

re: MJPEG vs. more compressed files like H264/265

Is there a camp asking that Canon drop MJPEG?
I would assume that the pro h264 camp is asking for a smaller file size/more compressed OPTION.

EG: Please give me the option to shoot in a compressed jpeg file size for thousands of images on my 16GB card vs. shooting RAW for a few hundred shots.

People chose to forgo the RAW files superior image quality all the time, and though I shoot RAW, I would never want a DSLR that did not have the jpeg options we now have.

So I can see the desire/need for a more compressed file type, but don't see the argument against the option.

Actually I believe some of the opposition to MJPEG has come from the editing world; because the performance during editing is poor, and you need to go through an intermediate format. I'm not quite sure why that is (especially given the similarities internally with ProRes). Maybe it's just that software tools haven't been optimised for MJPEG, and therefore don't utilise hardware acceleration correctly.

If Canon had offered ProRes, I suspect people would have been very happy.

H264 is a slightly different kettle of fish; in that it's arguably a delivery format, rather than one better suited to editing.

Anyone know what the expected cost will be in AUD?

As to the "7D MK2 has dual" that is a sports/crop camera built for speed. The 5D, has been up until the Mk3, a 'studio camera' of sorts. The Mk3 changed that but if they dropped a dual processor in the camera it would seriously come into the 1Dx realm. With the 7 FPS I doubt it is a dual processor. Just a newer and slightly faster single.

Price is going to be interested. I foresee the SAME release price as the MK3 where as from my understanding the exchange rate has become drastically different.

Question guys.. Is this the "new feature" they were talking about? able to change focus in post? Am i understanding this correctly?

Dual Pixel RAW: record one normal RAW file as well as a Dual Pixel RAW file. You can then use Canon’s Digital Photo Professional and have access to three new post processing techniques listed below:
Image Micro-adjustment: by using the depth information, fine adjustment enables the position of the maximum sharpness and resolution
Bokeh Shift: to change the position of the previous blur (original: re-positions the viewpoint of foreground bokeh for a more pleasing result)

The CR posted specs list "Compact Flash type II"

Really? When was the last time anyone made a type II compact flash? Like 2004?
Is this on my 7D2? (at work, no cameras on hand)

Must be a typo. 5d3 manual states it cannot use cf type 2 or microdrive.

It'll only be by a tiny amount, but possibly, yes.

There are probably a lot of clever things that could be done with that data (I was speculating on improved noise reduction a page back), so it'll be interesting to see what happens.

I think it will be around $4000 US. People are going to want one, so why not?

As for the kind of card, wouldn't surprise me if it's like the 7D2, but then again, I've been surprised before. With SD cards being so cheap and easy to use, but I like the CF cards. Don't drop them as much. :) I haven't bought a CF card in years.

probably won't be priced above 3500 USD, imo.

I have a very solid prediction it'll be 3299.

tend to agree, that way they can include the new 24-105 for approx 3799 and keep the kit under 4 grand.

I just did some research on 5D launch pricing over time.

5D - 2005 - US$3299 - 389k Yen
5DII - 2008 - US$2699 - 291k Yen
5DIII - 2012 - US$3499 - 283k Yen

At today's exchange rate the 5DIII's price would be US$2824.

I bought my original 5D in 2008 for under $2000, just a few months before the Mark II launched. I was shocked when the Mark III launched at $3499 and didn't buy one until I was able to snag a "nearly new" one on POTN for $2750 about 18 months later. If the Mark IV launches under $3000, I'll probably jump on it sooner rather than later before the value of my current camera declines into oblivion like my 5D did.
