More Specifications & Images of EOS 5D Mark IV

What's the "dual pixel" note on the spec list?

ever possible to no post-processing of the adjustment dual pixel RAW file (bad translation)
“The way Dual Pixel works, 30MP DP sensor means a 60MP dual pixel raw file with a new RRGGGGBB pattern (vs RGGB), so potentially better dynamic range, and maybe an improved debayering algorithm.”

Is that like Dual ISO in Magic Lantern??

We don't know, but it might be similar to that, yes.

If the "dual pixels" are the same as in "dual pixel AF", the quote in the original post sounds like BS.

It is most likely is not "like Dual ISO in Magic Lantern".
You have one half of bokeh balls in one of the dual pixels and the other half of bokeh balls in the other one. So bokeh will be absolutely awful if the saturation points of the pixel halfes are different.

You might draw depth information from the dual pixel information, but dynamic range will very likely not profit from it more than it would from just storing the sum of both pixel halfes with one additional bit.

I would love to see these bokah balls that are 1/2 a pixel wide and resolved as a ball when demosiaced.

sounds like BS .. you do realize we're working on translations.. right?

It's an AF area selector.

How confident are you about that? This was from the CR3 source that basically nailed everything else last week...

"Other ergonomic changes, such as a new locking switch on the rear of the camera."

Don't know if someone mentioned this - not read all 240 comments - but when I last worked on image sensors I came across a dual pixel device which had a small photodiode and a large photodiode making up one element. The small one would be used for bright lights and the large one for low lights so combining the two will give a dynamic range improvement over a single diode pixel. I guess both pixels are available in raw - hence RRGGGGBB - but this would really be a small RGGB and a large RGGB. For 30Mp the camera probably works out the best one to use.

I'm not sure that would work.

they have to be used computationally, not separately. there's parallax if you take them separate.

you can certainly use different ISO / levels though. especially if one side is clipping. so what canon may do is purposely underexpose one side. but when you tone map you take into account both sides of the exposure, and you never highlight clip. thus if one side clips hard, you have the actual value -1EV or -2EV on the otherside, and you can computationally put them back together.

think of it as an advanced ALO or HTP.

It's in the same place as the AF area selector on the 7D2 battery grip, and looks pretty much the same except with some texture added to it. It would be weird if it was anything else - and what would it be locking? The rear control lock is already down below like it always is.

It was described to us as a "locking switch", but we have no real information as to what it does.

The new lock switch is already clearly in view at the bottom under the large thumb wheel. Are you saying the weird new button/switch/knob between the large thumb wheel and the AF joystick is another locking switch?

My money would be on it doing something other than locking. Perhaps a customizable button, an AF mode select button, an AF point selection tool, etc.

Is the button next to the Q button EVF/OVF selector ???

DO IT.

Not shockingly, we're seeing a 2:1 ratio of complaints to fist pumps (so far).

That would 100% have been on a spec list. An EVF/OVF would be a gamechanger of the highest order and would have certainly been listed as a key selling point.

So I doubt that's what it is. (Would be awesome, though.)

I honestly have no idea, but I don't see why the source would specifically mention the marked locking switch, given that it doesn't seem new at all.

Why do people bother making things up and then coming on a forum posting as if they have any real knowledge about a working, non working, or theoretical technology?

Nobody knows what Dual Pixel RAW is, so please don't argue with someone's theory that MIGHT know a bit more about image sensors or the camera in question. ;-)

 

[mkush]

I know this is picky but I'm surprised that the mode dial looks like the old 5D3 and not like the newer 5Ds/R and 7D2, which I think looks a lot classier. Did anyone else notice that? Is there any doubt about the reliability of these pictures?

people are complaining about specs that haven't even been published yet (like the "person" that went off the deep end because he fantasized about a 1/100th sync speed)

Debating what dual pixel RAW is, is at least in the realm of conversation.

Can't say I did notice that. What difference are you even referring to? The pattern of the tiny gripping bumps around the side?

These days...everyone's an expert...until you ask them to show you their photos....

Well, since there have been a ton of magical unicorn dreams on this thread, I'll add one more. Perhaps it locks focus using face detect, so that the focus point follows the subject across the frame. Now, I'd be pretty ticked because the 1Dx doesn't have that and it's unlikely, but hey, why not dream?

Well actually yes, the bumps are different but that's not what I meant. Below is a link to a good shot of a 5Ds/R mode dial. The bumps are in a diagonal pattern instead of rectilinear. But what I really meant was the top of the dial. On both the 5Ds/R and the 7D2, the letters are raised and there is no visible silver ring. On the 5D3, and these pics of the 5D4, it just looks like a round piece of metal that they printed the stuff on. Does it matter? Of course not. Yes, I think the 5Ds and 7D2 look better. But my bigger point was that it made me question the 5D4 photos because I assumed that once Canon changed something like that they would stay with the change.

Here's a good shot of the 5Ds dial:

No, what it suggests is that within each R, G, and B pixel, there are two individual photodiodes instead of one. One reads from one half of the lens, one from the other, generating phase information. And together, they provide a brightness value for the entire pixel.

Thus, you can arrange AF pixels without losing imaging pixels, as opposed to other on sensor PDAF wherein the AF pixels replace imaging pixels (which isn't a big deal if you have a relatively small number of them).

But that's not new. Or at least I didn't think it was.

DPAF is established, albeit I'd suggest it's fair to call it "new" relative to existing OSPDAF.

huh.

that DOES look alot nicer.
