Chances of 5D MkIV have better dynamic range?

I switched and been a happy camper. I'm happy with Nikon's sensors which perform all around when it come to DR and ISO ( low and high). I've been waiting for Canon's answer since the 1Ds 3. That's almost six years! :)

Seven years. 1Ds3 was 2007...

We don't even know the likelihood of 5D4 coming to being or even to coming to a "rumor" stage.

Canon probably started working on 5D4 a month before or month after 5D3 was released. question is if they managed to come up with better sensor in that time. if MP, noise and dynamic range is all pretty much the same. what is the point then.

At this point I wonder what Canon can possibly do to make the 5D IV a compelling product without taking a substantial step in sensor quality. I guess they can load it up with "cupholders" like wireless, GPS, etc. but is there enough of that kind of stuff [that doesn't improve IQ] to make a 5D IV compelling? I don't think so.

I don't think they can do anything compelling without also changing sensor. Which is a reason why I think Canon isn't trying to do anything compelling until they are ready to release a new sensor.

The main exception was basically the 70D dual-pixel sensor, which was compelling enough on its own to motivate it to be released even if it did not represented a leap in dynamic range.

To answer the original question concerning DR. Unless Canon decides to employ Sony technology or create an equivalent the chances are slim to none. The DR is decent on the 5D3 but it isn't the same as Sony technology. Tomorrow may be a different story.

I think they need to be a little more aggressive than that. They need to take the lead not just catch up.

The DR is technically decent (not Exmor-like, but decent), but the darkest few stops are so badly affected by pattern noise that they're essentially unusable, especially if you need to do any sort of processing to bring out the shadows.

I'd say the functional DR is 3-4 stops less than the measured DR due to this pattern noise. The 6D has a similar measured DR, but the lack of pattern noise means that the usable DR is much greater.

Both cameras, though, are sorely lacking resolution for making large, detailed prints. 20/22MP was good for 2008, but inadequate for 2014.

I can't argue those facts. Let's see who does what next. Is there room for improvement and how practical is that for consumer and pros?

You could step up to a medium format digital
14 bit files, more MP and more dynamic range.
You will be limited to very low fps, manual focus or glacial AF though.

The solution to Canon being far behind the leaders in image quality isn't just to jump to medium format. Not only is it clumsy, inconvenient, impractical for any kind of action shooting (the same trip often combines landscapes and wildlife) and requiring a whole new set of lenses, but the Hasselblad and Leica 40MP sensors produce images no better than the A7r or D810.

It's like saying 'get a truck' because no-one makes a decent trailer that fits your car.

I love my Canon gear for my wedding photography. I love the 600EXRT's built in radio, I love the 5D3's not too big filesizes.. lenses etc... functionally everything is great.

But... but... that dynamic range :( My style of shooting lends itself very well to have that wide range as I prefer to underexpose for the highlights and bring back the shadows, but I'm very limited with that 5D3 sensor.

I get the itch to switch over to Nikon for the DR alone but then I'd be giving up on a lot of functional things that I love about the Canon system. How likely are we to get Nikon-like DR in the 5D4? Is this even something Canon cares about for it's consumers? DR actually went down from the 5D2 to the 5D3 so that's not a promising sign.

What are you shooting that makes the 1 stop difference in dynamic range between the D4 and the 5D so necessary to have?

What 1 stop difference?

More like over 2 stops between the D800 and 5D3, plus the lack of pattern noise in the former which makes for 5 stops or so greater usable DR (since pattern noise makes the darkest few stops on the 5D2 and 5D3 practically unusable, except for web-sized images).
