Update: Digicame-info also posted a detailed specification list. I added the Dual Pixel RAW information leaked at Nokishita Camera (see below):

Original post

A more detailed specification list for the upcoming Canon EOS 5D Mark IV leaked at Nokishita Camera.

Although the text is machine translated from Japanese, I think it is getting clearer what Dual Pixel RAW means and is for (the text in red above). My interpretation of what leaked so far is that Dual Pixel RAW is a technology that will allow for some focus adjustment in post-processing. This is something we know from light-field cameras like the Lytro.

I think the text below leaves no doubt. For instance “normal image and the parallax information” makes me think there is more than one image that’s taken on more than one focus plane. And “by using the depth information, fine adjustment enables the position of the maximum sharpness” seems to point to the possibility to shift the focus in post-processing, as does “Bokeh Shift“. As far as I understand, the “focus post-processing” will be available in a new version of Canon’s Digital Photo Professional software.

Well. Canon is going to set another technological milestone.

Let me know what you think about Dual Pixel RAW, am I right with my interpretation?

Announcement information

The EOS 5D Mark IV will start shipping in the mid of September 2016. Launch price should be €3,799 in Europe and $3,299 in the USA. Please note that I am not 100% sure about the US price, could also be $3,499. Maybe $3,499 is more likely.

No price hint We know the price for the EF 24-105mm f/4L IS II USM ($1,099) and EF 16-35mm f/2.8L III USM ($2,199) lenses. The EF 24-105mm will most likely start to ship with the EOS 5D Mark IV (it’s a new kit option), while the EF 16-35mm may be seen a bit later, probably in October.

Canon is set to make a big announcement on August 25, 2016. The following gear (and new EOS 7D Mark II kits) will be announced to the world:
